    This is for both the 4TB and 2TB models as I purchased both. For those looking to upgrade to a bigger internal drive in either, beware that the Xbox One will not support bigger than 2TB and the PS4 4TB respectively.

    In terms of performance don’t expect instant loading for games/levels, but you should expect that they will load a damn sight faster than before. However the biggest benefit is noise reduction from each system, the PS4 Pro in my case ramps up on digital games regardless but is otherwise silent as any system can be. The Xbox One is the biggest benefit as it becomes damn near silent regardless, to the point if I wasn’t using it I would wonder if it was on as the original drive is just that noisy.

    Regarding useable space The PS4 Pro gets 3.58GB with 4TB, The Xbox One gives 1.6TB over the paltry 840 – 860GB respectively. I would say that this is the best bang for buck upgrade, especially if you’re looking to preserve games on older consoles like me. With games like Forza horizon 2 and 3 either outright disappearing from the store or losing dlc as an example, this is probably the best option to keep them around as external storage either brake or get used for other things.

    I bought this SSD to replace an HDD and to store all my music on my QuietPC. It was easily installed and is very fast to select and play an album. Storage is 4Tb so there is room for more music.
    Highly recommended.

    Please be warned that you really need some computer experience to get anything above 2TB as a boot system. I wanted this for my operating system and I spent about five to ten hours getting this to work. Firstly you need a bios that is capable of UEFI if you do not have this, then you will not get this drive to work. Well you can get it to work, but only for storage and not for Windows 10 as an example. If your computer is an old system and can only handle MBR which is the older file system then it will only register two terabytes, which is why you need UEFI and format the drive as GPT. If you are scratching your head wondering what I am talking about, then anything higher than a 2 TB unless you are using for storage will not be for you. I had to use Rufus and a copy of Windows on a USB stick. I shall buy another one in the future, I cannot comment on games etc etc as I do not play them, but for storage it is more than suitable.

    Samsung is the only brand I buy apart from the Crucial MX series. It is worth the extra 10 over the cheaper options as it will not slow down randomly when you need it the most.
    Plugged in, partitioned and formatted in seconds, all good.
    The Blackmagic RAW write/read test came out better than my Macbook Air M1’s soldered on SSD.
    Enough said. 😉
    Notes:
    1. It comes with no screws, you have to buy your own. I used double sided tape instead.
    2. Like all SSD manufacturers, they cheat with the size. It’s not 1TB, it’s 1,000,000,000 bytes that actually works out as 931MB storage space. So don’t be surprised if that’s the free space you see, it’s by design.

    Golden Review Award: 3 From Our UsersI replaced two 5TB 2.5″ HDDs with two 8TB QVO 870s at the end of June 2023 when they were 399 each, I now see that six weeks later they’re only 339!

    One is in an always on NAS mini PC, and the other is my portable software repo, in a UGREEN portable USB C Superspeed plus enclosure (ASIN B07D2BHVBD)

    Nothing to fault. I now have far faster access to the NAS (the HDD used to spin down to conserve power), and I have a more lightweight solution for a software repo on the go. I run Bitlocker with a password on the portable drive.

    Only thing to note is that once the SLC cache is full (78GB), the sustained write speed drops to 160GB/s, not a big deal except to be aware of it particularly when you first load up the SSD with your data, or embark on sustained exceptionally large data transfers.

    Golden Review Award: 3 From Our UsersI Bought this 2 TB sata SSD so I could store all historical familiy photos within my PC. It has absorbed everything and more in record time, with the speedy silence expected from an SSD. Both my laptop and main pc are now exclusively drived by Samsung SSDs, after a recent mistake of buying a cheaper make, now rectified, I will not stray away from dependable Samsung again. I also have an off line 2TB Samsung SSD, for fast backup.

    Golden Review Award: 4 From Our UsersThis one I put in a Freesat 4k box. Undo two screws, spluger. Pull out four grommets. Disconnect, reverse process, bobs your uncle. Freesat 4k has the drive running all the time if set for app use. Steady sound with mechanical drives. Reports on the internet of the drives only lasting a couple of years so went for broke voided the warranty and put an SSD in it. Plan ahead :). Now no humming sound :).

    I’ve used the 850, 860 and this one now. Four in PCs / laptops Windows 10 upgrade ~ 2016 ish. One in Nvidia media player since 2018, no issues where it’s merged into Android main memory and my old laptop donated it’s to the Chromecast TV dongle when I outed it. Those cases can be used to put the drive in for external use, deliver USB3 how I got them on the Nvidia and Chromecast TV dongle.

    For PC / laptop you use the Magician software that clones the existing drive then pop it in. A cradle can be used during the process or one of those cases or a spare port. All very painless. You get the fun of where to put the drive in the PC. Mounts are sold to bolster them up to the normal size HD, plastic or a dummy card it clips into. Have used both. Might require a usb3 card if no port. Did that on one.

    100% reliable.

    5.0 out of 5 stars Smooth upgrade

    Golden Review Award: 26 From Our UsersIf you are looking for a fast, reliable, and spacious solid-state drive (SSD) to upgrade your PC or laptop, you might want to consider the Samsung 870 QVO 1 TB SATA 2.5 Inch Internal Solid State Drive. This SSD is the latest model in Samsung’s QVO series, which stands for Quality and Value Optimized. It offers a great balance of performance, capacity, and price for mainstream users who want to enjoy the benefits of SSD technology.

    —Pros—
    +The Samsung 870 QVO has a sequential read/write speed of up to 560/530 MB/s, which is much faster than traditional hard disk drives (HDDs) and comparable to some of the higher-end SSDs on the market. This means you can boot up your system, load applications, and transfer files in a matter of seconds.
    +The Samsung 870 QVO has a large capacity of 1TB, which can store plenty of games, photos, videos, and other files. You can also choose from other capacities ranging from 2 TB to 8 TB, depending on your needs and budget.
    +The 870 QVO has a long lifespan and reliability, thanks to its advanced QLC NAND flash memory technology and Samsung’s Intelligent TurboWrite technology. The SSD has a terabytes written (TBW) rating of 360 TB, which means you can write up to 360 TB of data before the SSD wears out. That’s equivalent to writing 98 GB of data every day for 10 years.
    +The Samsung 870 QVO is compatible with most PCs and laptops that have a SATA interface and a 2.5-inch drive bay. It also comes with Samsung’s Magician software, which helps you monitor the SSD’s health, optimize its performance, and update its firmware.

    —Cons—
    -The Samsung 870 QVO is not the fastest SSD on the market, especially when it comes to random read/write speeds, which are more relevant for multitasking and heavy workloads. If you are looking for the best performance possible, you might want to consider other SSDs that use NVMe or PCIe interfaces, which are faster but also more expensive than SATA SSDs.
    -The Samsung 870 QVO is not the cheapest SSD on the market, either. You can find other SSDs that offer similar or slightly lower performance and capacity for a lower price. However, you might also compromise on quality and durability if you opt for cheaper SSDs from less reputable brands.

    —Reasons to Buy—
    *You should buy the Samsung 870 QVO if you want to upgrade your PC or laptop with a fast, reliable, and spacious SSD that offers great value for money. You will notice a significant improvement in your system’s responsiveness, boot time, loading time, and overall performance. You will also enjoy more storage space for your files and less noise and heat from your system.
    *You should buy the Samsung 870 QVO if you are a mainstream user who mainly uses your PC or laptop for browsing the web, watching videos, playing games, or doing office work. *You will get enough speed and capacity for your everyday needs without breaking the bank.

    —Reasons to Avoid—
    *You should avoid the Samsung 870 QVO if you are looking for the fastest or the cheapest SSD on the market. You might be disappointed by its random read/write speeds or its price tag compared to other SSDs that use NVMe or PCIe interfaces or that have lower quality and durability.
    *You should avoid the Samsung 870 QVO if you are a power user who frequently runs multiple applications or heavy workloads that require high performance and endurance. You might experience slowdowns or reduced lifespan of the SSD due to its QLC NAND flash memory technology and its limited cache size.

    ———-Conclusion———-
    The Samsung 870 QVO is a great SSD for upgrading your PC or laptop with a fast, reliable, and spacious storage device that offers great value for money. It is suitable for mainstream users who want to enjoy the benefits of SSD technology without spending too much or compromising on quality and durability. However, it is not the best choice for power users who need the highest performance and endurance possible from their SSDs.

    Golden Review Award: 3 From Our UsersI had this old Toshiba laptop which I got when windows 7 was all the rage. The PC must be ten years old now. I had loaded win 10 but the PC was very slow to start up {over 5 mins} and sometimes overheated and shut down. So I got this SSD, they are not too expensive and easy to fit on the laptop. What a difference. I just timed it now and from pressing start to windows main screen {including logging on } was 21 secs. Shutdown was 11 secs. So now I am going to get a new battery for it. Also it has not shutdown from overheating and its been on all day. The fan I only heard once so that’s a winner too. SSD’s are also good when gaming as they reduce loading speeds but this laptop is not very good for gaming so couldn’t test that.

    Golden Review Award: 3 From Our UsersInitial impressions are good. I was surprised to see this drive was 25 LESS than the other drive I have (Crucial MX500 2TB) and that’s a decent drive so I hope this Samsung is better. I am a bit dubious about the TBW on this drive but in a good way. The TBW is the same on the Crucial (700) but according to it’s software (which also reads the Samsung and the NVME built in on the same machine) The Crucial has just hit the 1PB mark with 68% health and is still downloading at full speed for my connection (112MB/sec) so if the Samsung does similar I will be very happy!

    I recently upgraded to the Samsung 870 QVO 2 TB SATA 2.5 and it’s been a fantastic addition to my computer setup. The drive is lightning-fast and I’ve noticed a significant improvement in boot times and overall system performance. The 2 TB capacity is more than enough for my needs and allows me to store all of my important files, photos, and videos in one place.

    Installation was a breeze and the Samsung Magician software made it easy to clone my old drive and transfer all of my files over without any issues. The drive is also very quiet and doesn’t generate any noticeable heat, which is a plus.

    Overall, I’m very happy with my purchase and would definitely recommend the Samsung 870 QVO 2 TB SATA 2.5 to anyone looking for a high-performance and reliable SSD. The price is a bit higher than some other drives on the market, but in my opinion, the speed and reliability are well worth the investment.

    Copied hard drive to ssd. Then swayed memory RAM. Then reset the bios. The result went from 27 minutes bootup time with hard drive to what the video shows. About half a minute. Going to a reputable make and speed of ssd like this one will make a very big difference to the overall speed of your computer. Do not buy cheap unbranded ssd drives.

    Great drive. It has made my old laptop boot up in about 20 seconds instead of a few minutes. It’s worth spending a little more on this Samsung one because the software makes the copying process much easier. I would recommend it and would buy another if I needed it.

    Have tested severel times after installing it on a Thinkpad sata 3 laptop with new Windows 10 Pro, Low 80Mb/s write speed.
    Have returned it back, no good as it was specified over 540MB/s, that’s a huge difference
    Samsung is not so great as it used to be, unfortunately.

    Will update this if the drive fails, as it’s only been a week but initial impression is that it’s as fast as stated (ran windows WINSAT test) and it went straight in with no problems. You will need to initialise the disk in drive management in windows before you can use it – simple click process. Overall, decent value for money and my video processing is so much cleaner and faster working off this drive than the old external USB 3 one.

    Golden Review Award: 2 From Our UsersI’d already used a 128gb one of these to upgrade my desktop PC. These are so much faster than a conventional hard disk – you will really notice a faster boot-up time. In addition, if you are short of memory the page file will be quicker too. People typically use the SSD as the windows disk and use the original, larger hard-drive for all the data. This is fairly simple to do (samsung have migration software) but make sure you have space to mount the disk and an available sata socket on your motherbord ans a sata cable. Loads of help online if you are not confident. HELPFUL HINT: I thought I needed to replace my smaller SSD with this larger one because itunes insists that my partner’s iphone and ipad are backed up to the C-drive, hence my 128gb disk was not big enough. However, you can get around this – google “symbolic link” and “iphone backup” to find out how to fool itunes into using another disk for backups. This saved me having to use the larger SSD, which I returned. Sorry Samsung, but I have bought two of these disks so far, and it probably won’t be long until I want another one.

    Golden Review Award: 2 From Our UsersAt the price this is one of the best internal SSDs available. I use these as system drives in several laptops where they perform perfectly and fast. They more or less reach the top speed which Sata III is capable of so unless you can fir a PCI drive they’re about as fast as you can get. I’ve had no problem with failures – none at all. Several reviewer have commented on low continuous write speeds for very large transfers and this is a fact however it isn’t a limitation for most applications unless you have a need to frequently write large (>1GB say) files which most people don’t. For everyday use on a laptop they speed up performance over the usual slow spinning HDD by around a factor of 4, a very noticeable improvement. Most file transfers are much smaller in any case and read speeds are never impacted.

    The 1TB SSD I ordered comes in a neat carton.
    The drive itself is smart in appearance and is 2.5″.
    I was going to fit the much faster M.2 drive but my system is having difficulty detecting one of those (non Samsung) so I opted for this as I am only using it for storage and not gaming with it.
    Windows 11 recognised the disc and installed it quick time without issue.
    I quick formatted it and headed over to the Samsung web site to download the Samsung Magic software.
    This keeps an eye in the device for you and off a comprehensive suite of tools available for free.
    I made the purchase following many recommendations for reliability and having lost data in the past this is what is important to me.

    Golden Review Award: 6 From Our UsersI used a tooless installation kit to put this into my PC. Took about 15 minutes to install and boot the PC up. You need to install the magician software for driver and software that manages the way that the drive is filled up. You can’t just use this out of the box as mechanical hard drive because the solid state components can get corrupted. You also need to disable disc defragmentation on this item as well so you don’t get the same issue. The software records the temperature onboard the drive as well as the write speed. I have a data drive installed inside my PC 2tb. I moved over 700 gb from that drive in the the Samsung Drive and rather than being hours to copy over data it too seconds. The speed shows about 560 gbps. That is faster than my internal drive and external drives I have. The price now is nearly on par with mechanical drives ie moving part drives hence 8 plucked up the courage to jump into SSD tech. Samsung is also a name you rely upon for quality. The drive is 2tb but holds about 1.81tb. This is not one of those drives that continuously writes and overwrites files ie a faked drive. This is the real McCoy. Beam me up scotty. The drive is small compared to normal 3.5 and 2.5 drives. The SATA connection within the PC a Dell 870has two electrical connections I can’t remember the size but I think there was 14 and a 19 cable and connectors. You need to use the cable numbered 19 to power the drive. The Dell 870 sneakily hides that cable. Great product. Fast and easy to install.

    I used this to swap out an old HDD in my desktop PC. A bit of research helped the process, which is actually straightforward and worth the effort.
    There is a significant difference in speed which is the main reason. I used the Samsung free software too, which is fine.
    It doesn’t really need partitioning so needed a bit of extra tidying up to sort out at the end of the process. That wasn’t difficult, just required a bit more time and patience. However, the goal was a quicker solution which it has achieved. Hopefully longer lasting than my old HDD too.

    Golden Review Award: 10 From Our UsersI bought this SSD as a replacement/upgrade to our old ‘Late 2012’ 27″ iMac, after it started to cough and splutter a bit. I used it with a cradle to make is easier to secure it safely within the chassis and there are loads out there that perform this job well. (If you’re interested, this is the one I used: https://www.amazon.co.uk/dp/B07QVX8TWJ?psc=1&ref=ppx_yo2ov_dt_b_product_details). This new drive has greatly improved the performance and usability of the iMac. Before the upgrade I was thinking it was barely useable, particularly comparing it to my newish work machine, the drive has breathed new life in to the iMac. Tested drive performance is about 3x faster with the new SSD but this performance is most noticeable in the overall usability – booting, opening and closing apps etc.
    At 70 you can’t really go wrong, great value for money, and having used external Samsung SSDs before, I’ve never experienced any hardware issues at all. Highly recommended.

    Golden Review Award: 5 From Our UsersI installed this SSD drive on my 7 year old tower pc. As there weren’t any spare cables, I disconnected the dvd connectors and used them to connect the SSD for cloning. Having downloaded Samsungs Magician software, the cloning of my old HDD to the SSD was extremely easy. I then disconnected my HDD and fitted the connectors onto the SSD and reconnected the DVD connectors to the DVD.

    My pc used to take 5 minutes to start up. Now it’s 30 seconds. So not instantaneous but a vast improvement. The same is true for loading programs, much quicker.

    For 59, this was a very worthwhile investment, much cheaper than buying a new pc. It also avoided ditching the existing old software and being forced to buy subscriptions for the latest Microsoft etc software which come with new pcs.

    Golden Review Award: 3 From Our UsersBeing a SATA SSD rather than a high-performance NVMe means that out and out performance is limited by the form factor.

    I purchased this drive for it’s local storage capacity, and for this it does well, and performance isn’t too shabby – a benchmark when new returned 55,664 read IOPS and 34,912 write IOPS and a respectable sequential read throughput – though writes can sometimes be less impressive, sometimes performing 485MB/s and other times less than half that.

    However, after months of use the drive is still working perfectly, and the performance benchmarks are still performing well.

    This may be pricey compared to other brands, but you are paying for a trusted brand, and the excellent Samsung Magician software, for a drive that offers good reliability and reasonable performance.

    Golden Review Award: 4 From Our UsersAt 13 years old, my studio PC was starting to show its age. The C drive hard disk was intermittently crashing, and the machine was getting really slow. This new Samsung SSD has given it a new lease of life, akin to putting your granny on steroids. On switching the PC on it almost springs to life in a quarter of the time the it did before, and so far everything has been running smoother and faster, with no blue screen of death (again, so far).
    The instruction booklet that came with it seemed to be in pretty much every other language then English, but I managed to get it installed, and the contents of the old drive copied over pretty easily via the Samsung Magician software which can be downloaded from their site (after a small amount of detective work).
    I do have to say that it seems a little mean that they did not include a chassis that the SSD can sit in and be securely tethered inside the computer, at the moment the drive is sitting precariously on bundle of unused SATA cables. Other than that, I am pretty well satisfied.
