I like that you can use the downloads without re-installing on the xbox again the only thing that I’m not sold on was the price was very expensive for only 1 gb
Arrived quickly. Looks great, matched the white Ps5 well. High cost but in/around the margins for items that were of a similar size memory/storage.
1-total available space from the start is 4.6TB not 5TB, I can only
Assume the missing space is used to store OS data for the device.(happy to be corrected by someone with more knowledge).
2-you can only play PS4 games directly from the external HD NOT Ps5 games. They must be recovered from the HD across to the Ps5 PRIOR to playing. Example GTA5 takes about 20mins to move before playing.
3- literally a plug and play device. No additional actions required.
Bought for my daughter has original 500gb Xbox one . Saved her having delete saves and updates. She likes it cause it light up green.i like it cos I don’t get any moaning about my Xbox is full. Quality wise it good went for this one as compatible with series x I case she gets one in the future save money buying another harddrive if need . Speed fast and no slower than loading a save from Internal harddrive. She downloaded games onto it from Xbox pass and loads fine. Hope this helps.
Bought this for the xbox one. Came all programed and ready to use. Stores hundreds of games and simple to put away. Brilliant all round can’t fault it at all
Looking for a new hardrive since my other one was now full, happily looking through amazon i found a woderful 2tb one, easy install, easy format, so wonderful, thanks to amazon staff for there hard work, i really hope this helps people out in looking for an external hardrive, take care and thank you XXX
Does what it’s supposed to do. I bought one years ago to use with a PS5, and it’s plug and play. Works out of the box. I’m using it to store games on, as the less than a TB of storage that comes with the launch PS5 is not enough. It’s still working today.
Setting up the lights on it is easy. The drive comes with a link to the webpage to download the software pre-installed. Press the link, download the software, immediately have the ability to alter the colour settings. The settings are retained even if the drive is switched off or moved.
I just purchased a new one to watch media on a smart TV with. I did have to reformat it to NTFS to make the TV recognise it, but a simple ‘reformat’ in windows did the job and now it’s working fine.
I think 100 is too expensive for 2TB, but when it’s on sale for around half price that’s fairer. There are plenty of other hard drives on amazon that are slightly cheaper but aren’t from official companies are sound like they’re made in a basement in China, and amazon doesn’t monitor what’s actually on them so anything could happen when they’re plugged in. It’s worth paying a little bit extra to get one from an official company that’s known to be safe.
Lastly, selecting the ‘rainbow’ option for the LEDs obviously makes the drive work faster.
Can’t say too much really, plug it in and away you go extra storage, used for my series x stuff it works as expected, everything else I own sits on an 8tb external hdd, however as many others have already pointed out, its over priced for what it. Considering the 8tb external cost less than half as much, but then series x stuff won’t run from a hdd..Nice one microsoft.
For ps4 owners works as extra disc where you can install and play games- connected via front usb. Works fast- see no difference comparing to the original disc ( if not faster). Works perfect with PSVR. 2TB disc gives about 1.8 TB space.
As for ps5- as instruction says- it will only work as a storage from which you can install games to main disc of ps5. Cannot play games directly from the drive.
I have an xbox series s, so I’m limited to the amount of games I can play direct from desktop. The( x/s optimised ones). So this is great for me as I can get 6+ more directly playable games on it. Which is more than enough for me. It transfers from desktop to storage at a steady 6.4 gbps on my machine, so all in all I would recommend it.
Very fast transfer speeds when transferring games, and downloading them too.. But beware only certain xbox games are allowed to run on the hard drive with the xbox. Found myself transferring more off of there and deleting games in internal just to play them. Old titles seem to work the best with this drive. So a little disappointed on that, but not the drives fault. Just have to buy the expansion drive that goes into the back of xbox. Will use this for pc in the future… Its a pity that the xbox doesn’t tell you before downloading the game that only certain titles can be played on this hard drive, even though so-called xbox optimised and recognised & certified. A list should be created so your not downloading & waiting, only to be told it can’t be played from the drive, and needs transferring to internal. (Why do you think i bought it) It was instantly recognised and formatted for games and media. So a little disappointed but 4tb(3.7tb after formatting) for 119 pounds is a steal at that price. Nice touch with the green light to, my 3rd seagate drive, and had some for years and still going strong. Built to last. But check which games can be used with the drive, if you can before downloading them..
Makes very noticele noises when being used.
The writes speeds of 240 MB/s to 250 MB/s (roughly) are very consistent without any drops during huge transfers.
Some hard drives tend to have fast write speeds and then drop to a crawl after a few minutes but this device does not.
2 Month Usesage Update:
I have used as a 24/7 torrent download the part of a month (February 6th to March) and a then a few hours a day till this update (March 28th).
I have since noticed when using this to watch 4K HDR content on a PC there were a problems when it was freeze and crash the UI on windows. These would occur when running a movie from the HDD and scrubbing through quickly from scene to scene.
This would happen every 20-30 minutes or so which is annoying forcing me to unplug the divide from the USB port to fix.
Although it is meant to be a “gaming/storage” hub my guess is that my usecase of heavy 24/7 downloading affected it.
Something to consider if your a heavy torrent downloader and wish to use this as a media storage.
Top bit of kit and a must have if you have lots of games and dont want to save on external HD and then move back to play and so on. Only down side is the price.
brought this specifically for the xbox and now on PC it works well still, note that if you do that same move you need to format the hard drive to get it to show and be able to work with the computer, however it will work if you go straight onto the computer.
whilst the speeds aren’t exactly nvme speeds but then you get 4tb for a much lower price and personally this is my second hard drive now as I like the option for space. The drive has worked since day one and hasn’t crashed at all and none of the files have been corrupted since ownership. the storage is really good too, 4tb is a massive amount for games and other files plus having 2 bumping up to 8tb really there isn’t much you can’t download.
The connection is usb is 3.2 for the better transfer speeds, again whilst you aren’t getting the speeds of the nvme drives it is still really good transfer speeds.
overall a great purchase the compact size does allow for easy portability if you need too, and the light green bar does give a little nice flair to the drive. The drive also comes with a 1 year backup warranty if anything is lost which is a nice additional touch to purchasing this the drives have not missed a beat and thoroughly happy with my purchases.
All you have to do is plug it in and format it, which for some reason is either games OR media. You can then set it up to automatically receive everything downloaded or solely backwards compatible games direct to this drive. Any BACKWARDS COMPATIBLE Xbox, Xbox 360 or Xbox One games ARE PLAYABLE direct from this drive. All Series S or X only content needs to be transferred to the console itself. It’s also whisper quiet (it’s brand new so why wouldn’t it be?) and lightning quick. For example; if you were to download and remove Series S/X games each time you used up or gained hard drive space on the console itself it could take hours each time. Download once, then copy or move games back and forth from this device in minutes thanks to the supplied 1Gbps capable cable.
The LEDs can be changed (of a fashion). To do this you need a PC and Seagate Toolkit software. You’ll probably also need them to install any firmware updates. From there you can alter the brightness of the green or turn it off. Users CANNOT alter the colour. You can also turn off the status LED. However, for some bizarre reason the green LEDs don’t switch off when the console is shutdown using a controller or media remote (02/01/24 – They do go out after about 5mins after the console shutdown), but they do go out when you shutdown via the main on/off switch or from within the Power Options whilst in Settings.
In conclusion: It’s excellent, provided you take advantage of its uses and understand its limitations. It could even become perfect if any forthcoming update solves the aforementioned power/LED conundrum (02/01/24 – appears to be unnecessary). Add SSD into the mix and it may well be unsurmountable. Do your console a favour and buy it.
Ladies, gentlemen, and everyone in between, buckle up for the epic tale of the Seagate Storage Expansion Card. This unassuming piece of tech turned my life into a digital rollercoaster of love, lust, and unemployment checks.
Let’s kick off this adventure with a date. Picture this: a cozy night in, dim lights, and me, attempting to impress my date with my gaming skills. Enter the Seagate Expansion Card, promising to take our gaming experience to new heights. Little did I know, my attempt at a smooth transition to the digital realm resulted in a glitch that left me pixelated in embarrassment. My date mistook my technological hiccup for a metaphor for our relationship—pixelated and glitchy.
Fast forward to a family gathering with the in-laws. Eager to showcase the wonders of my digital kingdom, I decided to plug in the Seagate Expansion Card to the Xbox. The card, however, had its own ideas. Mid-game, it decided to eject itself like a rebellious teenager leaving home, causing a family uproar that left my in-laws convinced I had unleashed a gaming demon upon their household.
Now, let’s dive into the workplace saga. In a misguided attempt to boost productivity, I brought the Seagate to the office, hoping to transform mundane spreadsheets into digital adventures. Little did I know, my boss mistook my gaming ambitions for corporate espionage. I got fired faster than a noob in a first-person shooter game.
Now, let’s address the one flaw in this digital drama: the card’s ejection tendency. During an important virtual meeting, the card decided to make a surprise exit, leaving my colleagues convinced I was attempting a dramatic exit from the company. If only I had known I’d be starring in a real-life soap opera instead.
But fear not, because amidst the chaos, the Seagate Expansion Card has transformed my life. The extra storage has made me a digital maestro, impressing women and attracting swimsuit models like a gamer Casanova. The allure of a man with ample storage space is apparently irresistible.
In conclusion, the Seagate Storage Expansion Card is not just a storage solution; it’s the unsung hero of my digital escapades. From date-night glitches to family fiascos and workplace wipeouts, this card has turned me into a pixelated legend. So, plug it in, level up, and let the laughter load!
I’m delighted to share my thoughts on the remarkable Xbox Expansion Card, a true game-changer for the gaming community. Developed in collaboration with Xbox, this expansion card brings a new level of seamless gameplay to both the Xbox Series X and S consoles.
One of the standout features is its ability to flawlessly run Xbox Series X|S games from either the internal SSD or the expansion card, all without compromising on graphics, latency, load times, or framerates. This ensures an immersive and uninterrupted gaming experience, letting players dive into their favorite titles without any hindrances.
Boasting a capacious 1 TB of storage, this expansion card significantly bolsters the overall storage capacity of the Xbox Series X|S consoles. With room for a multitude of games spanning four generations of Xbox, this card offers the convenience of choice without compromising the performance that players crave.
What sets this expansion card apart is its exclusive integration with the Xbox Velocity Architecture. This translates into speedier load times, more vibrant and detailed environments, and an overall more engaging gameplay encounter. The immersive worlds of our favorite games truly come to life, enhancing the entertainment value beyond measure.
Switching between various titles in mere seconds is a reality with the Quick Resume feature. This convenience is applicable whether you’re accessing games from the internal SSD or the expansion card, ensuring that you’re always ready to dive into your gaming adventures without unnecessary waiting.
Furthermore, the peace of mind that comes with the inclusion of a 3-year limited warranty is a testament to the quality and durability of this expansion card. It’s a testament to the manufacturer’s commitment to delivering a product that stands the test of time.
In conclusion, the Xbox Expansion Card is a must-have for avid gamers and enthusiasts alike. Its seamless compatibility, ample storage capacity, and exclusive performance-enhancing features make it an indispensable addition to any Xbox Series X|S setup. This expansion card truly elevates the gaming experience, offering more immersive, fluid, and captivating gameplay.
Firstly I like the fact that it just slots into my Series S, before anyone asks why I got this for Series S take into consideration that the S is perfect for travel and having a 1TB memory NVME SSD copy your friends game onto your console in in minutes is a lot more convenient than downloading it when your own the go or travelling. I also own a PS5 so, it’s kind of a needed thing for when I travel.
The read and write speeds must be amazing too, transferring between the two using Halo MCC only took 10 minutes and that’s impressive.
It’s also excellent if your using dev mode/emulation software. There’s nothing like playing original Xbox or PS2 games on the series consoles and having the ability and nostalgia factor of having it be used in a memory card shaped NVME SSD.
This XBOX expansion card is pricey but if you need more fast storage than you have it’s what you need. It’s good that you can take it from one XBOX put it in another and carry on.
As much as I absolutely hate the lockdown Xbox have on extended drive space with the new generation it had to be done.
I bit the bullet on this ruddy thing and whilst I’m glad I can now have a slew of old and new titles installed and admittedly cannot fault the product at all for its ease of installation or use – it is grossly overpriced when I look at other M.2’s.
However with games getting bigger and bigger, I felt it necessary, especially when I have the bad habit of jumping between four/five titles!
I purchased the 512gb expansion card on sale and is still around double the price of an equivalent nvme m.2 SSD.
But unfortunately on series consoles this is our only option of the 512gb card there is a usable 460gb
I think this memory is good but the price is too high
I got the 1 TB expansion card so I could play the xbox s games direct without having to transfer etc works grea
Expensive but, necessary if you need to add more storage for your Xbos series X/S. Easy to install and set up (on my Series X anyway). Don’t know if you pulled it out and put it back in a few times how durable it would actually be but, I use mine as a perminant add on space as opposed to a portable device. Dropped a star as it is simply to expensive for the amount of storage you get and has a monopoly on the devices.
I bought this as I had no room on my Xbox series S, after getting it I can now install many more games without having to constantly uninstall games in order to play another game. I would highly recommend this to anyone who has a series S as it offers much more storage and you don’t need to uninstall games to install big games
If you need extra memory on your series S or X then this is the only card you can buy. 1TB or 2TB from Seagate, its great at what it does, simply just plug it into the back of the Xbox and away you go, its very fast at installing and transferring data. Its just a shame these cards are a rip-off when it comes to the price, being forced to use these and pay these prices because there’s no other options. If you need that boost in memory space then this is what you need, over priced but reliable and easy to use.
Hard to review this really, it’s a memory card and gives you extra storage, duh. Super easy to use.
It’s a bit one the Expensive side, But the ability to boot up the games straight from the external hard drive. GREAT!!! Easy to fit, just Plug n Play & your off .
Delivered in good time which was important as it was for a birthday, as described and easy to set up.
Fortunately bought this when offer was on but would still have purchased for standard price anyway. Most games these days on Xbox range from 30-90 gb so storage fills up quick this has really extended the use of the Xbox as doubles capacity and allows to download games from store and play anytime. Please note that disc games bought also take up storage space so this memory card pays for itself. Definitely recommend very esay to set up.
It works seamlessly, you can hot swap it in and out, same speed as internal ssd. Have no worries about space for games now which is great. Shame they are so expensive but after 2 years of minimal storage I had to bite the bullet and shell out for it. Glad I did
WARNING! Originally received an opened box with the card removed. The replacement was thankfully unopened, present and untampered with. My fingers are now crossed that for this card, setup and use are smooth and fault free (I recommend you read other reviews pertaining to the issues of the 2TB card).
Ok it’s made for Xbox. It’s small and out of the way and sits there doing what you paid for it to do. Provide extra storage. Great. You can get much more storage for half the price. I bought it cause I wanted it and thought it was cool and to be honest that’s the only reason you would buy this over other options.
It’s easy to install you just take it out and slot it in on your Xbox series s or x and jus works seamlessly
On major issue is the price! There is just no way round it if you have a series s you need this product, it’s a must have but you might as well bought a series X for how much you would of spend altogether! The price is it biggest downfall!
So when you get this item and plug it straight into the console it works, do note the useable space you have on the 1TB stick is 919.9GB free of 920.0GB, that extra 80.1GB you loose is more than likely format software.
Don’t compare this directly to other PC NVME storage drives when comparing prices. These drives are a smaller standard of M.2 drives and are only being made by the one supplier for Microsoft so much economies of scale will mean a more expensive to GB of storage. For Series X/S titles that require the faster storage then this is unfortunately the only option for now. If you need more storage at a cheaper price then you can use other external SSD or HDD drives which will work fine with titles that don’t require the faster internal NVME drive, and will allow you to transfer titles across when you need to. A cheap SATA SSD will be a good drive if you play lots of previous gen titles that don’t require the fastest storage and the Series’s consoles will be able to load the games slightly faster (but individual titles may still be limited but coding or cutscenes that can’t be skipped).
For those of you who still don’t understand how storage measurements work in 2023: it IS what it says it is. For example, 1TB is 1000MB. But most systems don’t calculate space in that way, they calculate it using 1024 so 1TB actually looks less when examined. Why things are done this way, I don’t know.
The speeds of these absolutely miniature expansion cards is insane. Reaching nearly 6Gbps on my Series X and topping out at 3Gbps on my Series S, both speeds are fast enough to copy games in a matter of a few minutes. Velocity indeed.
Games also DO load from them. Any game will work but they are best reserved for Series X/S games. Original Xbox One games will load from a regular external hard drive but X/S will not. They need the speed offered by the internal storage or this expansion card.
Cost is about the only complaint, but most nvme is expensive at the moment and this is no different.
Absolutely excellent. Only niggle is the lack of clear instructions. You honestly don’t need instructions but I didn’t know if I had to plug this into my Xbox series X with it turned off or on. So I plugged it in with everything turned off for safety. Xbox couldn’t read it properly. I then had to remove it and plug it in with the Xbox switched on. This is the correct way to do it by the way. All good and working fine. Just remember to have your xbox switched ON and then plug the memory expansion in. Great piece of kit. It’s just like having more memory in your xbox. Need to change the xbox memory settings to allow the “xbox to choose” where to install games to as well mind.
Got the 512Mb expansion when price dropped to 85. It’s still quite expensive but probably worth it if you’re impatient like me and can’t be bothered waiting when moving new gen content between ssd and external hard drive.
It is just plug and play so is very easy to set up.
The one I ordered came from Italy so took 6 days to arrive but I knew that when ordering.
While I put this off, because these ain’t cheap, I bit the bullet because this was a good price and they’re only going to get more expensive.
Is it worth getting one? Well, if you play a range of games concurrently then yes. While you can buy a cheaper external hard drive and swap games on and off internal storage, having that extra 1TB means you can keep more of today’s huge games at your fingertips without worrying about space.
Installation is stupid easy and certainly more straightforward than a PS5 although you pay a bit extra for the convenience. That they are so easy to install also allows you to swap additional units out, if you have the money to spend.
Overall a great addition to your console.
Got an Xbox One X? Need more storage?
This is the Seagate Storage Expansion Card For Xbox Series X/S 1TB Solid State Drive, Available In 1 or 2TB.
This 1TB card is an essential bit of kit if you own an X, as that 1TB of memory soon runs out with the next gen games. More so if you have a Series S with it’s pitiful storage.
Maybe in a world where we are heading into cloud play, there is still a load of us who like to own the game. If you are using your console to it’s full capabilities you will need to buy the Series X versions of the games, and with this, they will need to be on either internal storage, cloud play or saved to this SSD slot in card. You will NOT be able to play Series X games from a normal external hard drive, even though you can save here and then reinstall to internal if needs be. A bit of a faff.
Overall I’d recommend this slot in SSD card, as it saves keep moving games around and reduces stress. OK it isn’t cheap, but I think you’ll find you will need it to double up on yer Series X storage.
Seagate Storage Expansion Card for Xbox Series X|S 1TB Solid State Drive
A must have if you have a large catalog of games. While the next gen systems are 1TB is size depending on the games that are installed your going to be using this storage up extremely quickly and you will be needing additional storage. While the older generation you could simply add an external HDD to expand the storage with the series X/S this root is closed off and your going to need one of these.
While Microsoft have given exclusive rights to Seagate this is the only way of expanding your storage at this moment of review.
What i like about this expansion card is it small from factor, the performance is as fast as the internal SSD its a few second slower in loading and copying however, its still fairly quick all while being extremely easy to install.
The one thing i dislike is the cost for 1TB hopefully over time this will come down price, while also the size of storage should go up in size as 1TB is still small with the size of games and the updates that accompanies them.
Received my 2TB expansion card today.
Pros:
1. Bumps my total X/S storage up to 3TB from 1TB (1TB internal + 2TB expansion card). Allows me to store and launch Xbox Series X/S enhanced games without having to transfer them continuously between USB drives and internal storage (or having to uninstall games). I still use my USB hard drives to store my library of non-enhanced games.
2. Very very very fast read/write speeds. Mimicks internal storage performance.
3. All I needed to do was plug it in and it worked straight out of the box. It’s also hot swappable.
Cons:
PRICE. PRICE. PRICE.
This thing is CRAZY EXPENSIVE.
Was it worth it?
For me, yes. While it’s dented my wallet quite significantly it allows me to store and launch substantially more X/S enhanced games and since, going forward, newer games will also require the faster storage USB drives are gradually becoming deprecated. Their only use really is for older games. Unless you want to constantly have to move games between USB and internal (a time consuming pain in the bum) consider investing in one of these drives. They’re backed by a 3 year manufacturer warranty as well. Divide 367.59 by 36 and it works out at roughly 10 a month. And that’s not factoring in that, realistically, it’ll continue to last way past the warranty period so realistically it’s probably less.
Should you buy one?
Well that’s entirely up to you. If you’re able to afford one and don’t like having to uninstall or transfer games between slower USB drives and internal storage (which is slow because of the USB drives limited read/write speeds) then go for it. There are 512GB, 1TB, and 2TB options to suit your needs. The 2TB one, while the larger investment, actually offers the cheapest solution of the three. Effectively you’re paying less per gigabyte than with the other 2 cards.
The Seagate Expansion Card is a brilliant product with the ONLY downside being the cost.
The Xbox Series X is a superb console but with a weak point. It only comes with about 800Mb of usable internal storage. In the past that would be plenty but with modern games often needing over 100Gb, you can easily find yourself running out of space. Now add into the mix a family that all like to play different types games and a xbox Game Pass or Ultimate (which we have) and the situation soon becomes desperate.
The only way around the problem (short of deleteing games along with open familily warfare) is to go for additional storage. That just leaves the question of which storage to go for…..
Low cost – buy an external 2TB HDD and plan WAY in advance which games you want to run off the internal memory. Also get used to moving games between the internal and external storage and for that to take ages and ages and ages. If running from the external storage then some games can have reduced features.
Somewhat Expensive – buy an external 2TB SSD and plan in little bit in advance which games you want to run off the internal memory. You will still have to move games between the internal and external but at least you dont need a calander to know when it should be ready. If running from the external storage then some games can have reduced features.
Expensive or Very Expensive – buy A Seagate 1TB or 2TB Expansion card, stick it in and carry on as normal.
As the Xbox only has a ONE expansion slot I chose the 2TB card over the 1TB. The reason being is that its size gives us plenty of storage to seamlessly save, load and play all the families games without having to shuffles which ones are stored where.
I got this for my XBox Series X as I wanted to use it as a back up source for the games currently installed on my XBox. Games can be so large in file size nowadays that even with a fast broadband connection they can take some time to download. So, by backing up all my games on this, I can quickly restore them if I ever had to remove any of the games, or factory reset my XBox.
The first thing that struck me when I received this drive was how tiny it was. It fits in the palm of my hand as shown in my picture.
Installation of the drive is so easy that my cat could do it. Simply plug it into the expansion port at the rear of your XBox Series X – and that’s it. No formatting, no setting up. Nothing.
I have about 500GB of games and data on my XBox’s 1TB capacity, but the speed at which this external device copies data from the XBox is phenomenal. In just a few minutes everything had been backed up onto this drive.
Yes, it’s a vary pricey product at 220, but it’s certainly worth it.
If you are looking for an external source to back up all your XBox Series X games, then this is the one for you.
I am not sure if you could actually install and run games from this external device, as I have not tried that.
Okay, I’m going to mention the elephant in the room and say that this is an expensive investment, and SSD’s are in fact quite expensive to begin with, however I’ve got to commend the design team on just how small and portable this SSD is. It’s extremely simple to use, you simply insert it into the expansion slot at the back of your Series X or S and it does the rest for you, if there’s no space on your consoles internal SSD then it’ll automatically install to the portable expansion card. The counter argument to why it’s expensive is because it uses the same architecture inside of the Series X, so games will play and feel as if your playing them from the internal SSD itself. There’s no compromise whatsoever, to quote Bethesda, it just works! I feel in this day and age games are so big these days that it’s almost a given that you’ll need to shell out for extra storage. Of course you can run older back compat games from your already current external hard drive but the caveat there is that you won’t be able to play any of the Series X or S optimised games from that hard drive, you’ll either need to have them installed via internal SSD or the storage expansion card.
So to summarise, I think it’s a brilliant piece of tech and it’s definitely essential I’d say if you’re a serious gamer, it does almost cost as much as the Series S and nearly half that of the Series X but it’s just convenience and doubles your storage in the process. You could argue that Microsoft could have expanded the internal storage but same issue, the consoles price itself would increase. While it’s not essential for the casual gamer that maybe only goes between a few games every couple of weeks, I’d say it’s a great purchase if you have the money to spare and if you game quite a lot!
