A must have if you download loads of videos and music
I kept running out of storage on my phone so I bought myself a
SanDisk 1TB Extreme Portable SSD. Its got super fast read and write speeds and can hold all my videos and music with ease.
very satisfactory purchase
I have two of these ( and got cases for them as well) . Saved all my CD collection on them (one at home, one to travel with). A breeze to operate, very fast, very portable. Regular USB adapter very handy.
Fantastic
This is a fast, robust SSD , with 2TB of storage. Purchased at a Amazon deal price that makes this a very cost effective storage solution at 121! Highley recomended. Also can take files from both Mac and PC!
Great external hard drive!
Great external support the device allowing you to easily carry ‘everything’ with you. This is the second hard drive and I’m really happy with them. They do exactly as explained, I use them to backup my business work.
Bought to replace a traditional HDD that had a head failure leading to a 400 plus recovery service cost.
Small, light, fast, is USBC with a USBA adapter. I also have the Extreme Pro version of this drive.
Fingers crossed, so far so good.
I bought 2 of these to be used as time machines on my M1 max MBP. With read / write speeds up to 2000mbs I was impressed but when tested on Black Magic i was getting slightly less than half of what is on the box.
I spoke with Sandisk (western digital) who said that this is not a thunderbolt compatible device and Macs only work on 3.1 rather than the 3.2 gen 2 that’s needed to get the most out of these drives. I then chatted with Apple who confirmed that all their Macs work on 3.1.
So . . .unless you buy a Thunderbolt 3 or 4 compatible SSD you will only get around 1000mbs and not the 2000 you are probably wanting and paying for. Dont blame the SSD it is a Mac thing but the box could have pointed that out I suppose
Used this straight out of the box as would be expected. I needed this for music production. I got to 1.8TB of data saved when it crashed. All files had disappeared and my computer said the module was unformatted so I had to start all over again after reformatting. It would seem its not able to cope with being used all day. On a positive note. Very small and portable and I am able to use files from it very quickly when producing music which puts less strain on my iMac’s memory.
Lost all my data when it failed for no reason. It lived in a dry and clean office with light usage. Just to be clear, I’m not a moany 1 star reviewer that complains because he doesn’t know how to use the product. Try Googling this product and you’ll find that this drive has a known problem. You’ve been warned!
Brought this a year or so ago and it stopped working about 6 months ago and there’s nothing they can do about it so now lost approximately 2k photos. Tried data recovery program but cannot read drive.
As a music producer it’s very essential for me to run VSTs using SSD, I was able to transfer all applications onto the SSD and free up a lot of internal storage of my MBP.
Highly recommended!
Couldn’t believe how small it is, basically the size of a credit card. I need to store and access big files and be able to switch between machines (laptop, macMini) often. I’m always on the go or travelling, this portable SSD is just perfect! Safe file storage. This small drive is also very robust! And you can attach it to a keyring, carabiner hook or similar. Clever.
just what i needed
great price, great product. was looking for a hardware encrypted device and was able to find one from amazon as such a great price.
product arrived safely and well packaged.
Didn’t have enough space for Baldur’s Gate 3 or Starfield. The external drive works really fast and both games load quickly. The drive is quite light. The lead is quite short but the space in the device mean you can hang it from another lead to stop from hanging.
Well-known reliable quality brand, good capacity, size and weight.
If you’re going to use one of these as I did, to make an image of your laptop disk for protection against losing your system and all the contents, then you want to have something totally reliable to store it on.
I doubt you’ll find much better than this, so its worth every penny. There’s also a nice little case available to keep it in!
During a promotional period, I made the decision to purchase this product. In my assessment, it’s an excellent hard drive that boasts rapid responsiveness. I’ve employed it to store the video files related to a feature film I recently shot. One noteworthy advantage is that I can edit the content directly on this device without encountering any delays, eliminating the need to transport it to the picture editor for further editing. I found its functionality to be so satisfactory that I proceeded to order an additional unit.
4atab for this price in this compact size is marvelous. I’ve already had the 1TB for a year and it’s great. I’ve read in other review that both these do start disconnecting. I had this problem too but bought a new high bandwidth cable cable and its solved it. Now I’ve got this 4TB one and I’m just as happy with that. It is fast. Really fast. 510Gb transfer worked out to be 3 seconds a gig. It ain’t 1 second. But it’s enough.
Apparently my worst delivery with Amazon is for my most expensive order. Cannot believe how you treated this tiny little box..I’m speechless
Product – tiny lovely and wonderful gadget. A bit manipulated by the advertising speed tho…. it gets to around 80mb when I copy the data over….
Great quality , huge capacity and fast in writing and retrieving data
The investment is truly justified in terms of value for money. Having purchased it a few days ago, I’ve begun transferring all my data from various PCs and laptops. It’s notably swift in writing data compared to other products, and its compact, portable design is a plus. However, it’s important to note that data transfer speed can fluctuate between 80-200 MB per second, potentially influenced by the speed of your PC or laptop. This is due to the bidirectional limitation in data transfer, so it’s advisable not to anticipate exceedingly high speeds on your computer or laptop. Nevertheless, this speed proved satisfactory for me, allowing me to move approximately 1 TB of data in just a few hours.
Great size and potability
Great, although I wish there was a way to magnetically stick it to my laptop 🙂
If you use a Mac reformat this to HSFS, as that will avoid some of the risks when unplugging the drive. I did trash mine by unplugging carelessly
Massive storage at a great price!
Bought the 2tb version of this SanDisk portable SSD and it is perfect for storing all our photos and videos from travelling. It can be easily connected straight to your phone to add or remove photos and videos. Its so small and lightweight making it easy to bring it with you wherever you go. The price is extremely competitive making this great value for money!
portable and super fast transfers
Gone are the days of waiting hours for slow transfers. An SSD drive is one of the fastest for large file transfer. The Sandisk extreme portable SSD is smaller than my iPhone and fits into the palm of my hand.
It is lightweight compared to my Western drive, and feels rugged to take everywhere with me. Comes with additional adaptors to use the traditional USB A ports but I highly recommend using the USB C.
So Tiny!
I knew these back-up drives were getting smaller, but I really hadn’t realised how small this one is. And the little cut-out in the top corner means you can loop it onto something so you don’t lose it. Have done one back-up and it was super fast.
Great produc
I love how fast the SSD is but I must say that I bought for one price and they decreased a lot after 1 month so I got a bit sad with that. If you have the chance to wait they normally will cost you cheaper.
Fast, Fast, Fast (On a Mac studio)
On it’s maiden voyage, it started of really slow, and I thought WTF! Then boom, GB transfer of data, 1 GB faster than a second. So it’s great purchase and it’s so tiny! Just copied 200gb whilst doing this review!
SSD drive
Wanted another SSD to save all my photos. I’ve had this make before and no problems so I’ve bought the same again but the price now a few years later has come down. Nice & compact which is good for traveling with.
Bought this to use pretty much exclusively for my iPad Pro to store photo and video from my Apple Photos library from an ongoing home renovation project & edit video from it in Lumafusion. It’s literally the definition of plug and play, and compact enough to fit in my pockets when out and about anywhere if working on it out of the house. Would happily buy another in future to expand storage for any of my devices.
Fast but gets ho
I bought this on Amazon Prime day. It is such a good deal. The write/read speeds are close to spec. The only thing that worries me is how hot it gets during backup.
I have two of these SSD’s that I carry with me everywhere and use them to back up my photos and laptop. When I get home I just plug them into my NAS and download images straight to my storage.
On their own they are pretty tough – I have occasionally dropped them with no ill effect. Protected in the small dedicated case, they would have to be trampled by an elephant to break. A bit pricey, but worth it!
Heads up if you’re thinking about buying this! My model is fine, works as it should, but be careful because there are some models out there with a fatal flaw where your data actually starts deleting itself. The way to fix this is through a firmware update by Sandisk. You can check on their website if you have an affected model or not.
Other than that, I’m quite impressed with it and it was super fast to transfer files across. Feel nice and sturdy and is super small!
On three operating systems (Mac, Linux Debian, Windows 10) I have had the same problem. I run an experiment and capture approximately 20Gb->300Gb of data in RAM and then offload it via USB3 to the SanDisk device – I get around 200M bytes/s – not blistering, but fast enough. The problem comes when I have another large file to write, the card just has zero bytes transfer. It sits there for a couple of minutes and then resumes. The files are written correctly, the CRC of the original and copy are the same. It does get very hot, even when idle, much hotter when writing, perhaps it is a thermal problem?
Doesn’t work on older macs with supplied cables
Seems good enough. Goes by work on an older 2014 iMac with the supplied USBC and adapter. Just doesn’t appear. Had to use a different cable and even then, it disconnects after about 10 minutes. Not sure why but works ok on a newer MB Pro. Maybe not for you if you need it to back up an older machine
I primarily brought this drive to use with my MacBook and Time Machine backups. I used to use a smaller thumb sized 2TB drive and these backups would often take over a day to complete, and would very often fail or time out. Upon receiving this the first thing I did was set up this drive with Time Machine, and the first backup completed 150GB in under 45 minutes, a drastic improvement.
The drive is nice and wallet sized, and fits in my rucksacks pockets when I am away. The only draw back is the cable is very short. It is fine when using my laptop at a desk, but when I use it on my lap the drive just dangles by the wire. Being a USB-C connection does allow any wire to be used, which is also handy. The inclusion of a USB-C to USB-A conversion cable is also a bonus.
SSD
This is my second one. They are great, reliable and very quick.
Not as fast as quoted
Small, Good storage, but seldom reaches high R/W speeds, even connected to and to 11th gen I7 SSD laptop, so for me has some limitations, I have a 4tb standard drive with better read write speeds, but it is small form factor of this drive that makes it useful.
Satisfied
So far it seems to be reliable product. Good speed. And nice dest.
Works with Tesla dashcam
I use this for sentry and dash cam in my Tesla, works perfectly.
Super produc
Zero setup, easy to use, for me using a Mac. A little pricey but happy.
Bloody brillia
I use these drivew almost daily as a video editor and they are fast reliable and compact. They have geniuenly changed my life, I now have half a dozen of them. Would recommend them to anyone!
Seem to be missing 70gb???
Nice and compact but started putting stuff on it but, 70gb seems to have disappeared???
No issues with it apart from this.
Fast disk at a good price
Super little drive, didn’t seem worth the extra for the Pro version given the mind-boggling USB compatibility maze of specs. So good, I bought another.
Fast delivery and high quality
They are not much different but extreme and extreme pro are not the same and can be overlooked sometimes.
This onehave little bit different shape than extreme pro but this can be totally ignored as read and write speeds are so similar.
Excellent Product should be a little cheape
Brilliant portable HD. I’ve been using it for video editing projects and speed is fantastically good. Has USB C connection only so if you need a USB port then don’t worry it comes with a little connector. I would buy again.
Lightweight and Rugged SSD.
A good quality, fast SSD. I thought this would be a bulkier unit however it’s actually quite small. Stores everything I need it to for my P.C / Mac and is rugged enough to last until failure.
It's SO FAST!
I use it as my main SSD on my M2 Mini and it flies! I couldn’t be more impressed. I moved 29Gb worth of data in one go and it took it less than 30sec to complete! I was a bit weary it would require formatting when using a Mac, but it was plug n play, so that also was super convenient!
Highly recommend
Bought this for video editing – to use as a work drive, storing the original RAW footage (regularly backed up, obviously) while working in Final Cut Pro.
This handles the transfers effortlessly and allows me to edit 4k footage with numerous effects applied, without dropping frames (Macbook Pro M1 Max) – all while working on the footage stored on the Sandisk SSD, not my internal SSD..
I’ve thrown a lot of work at it and it gets warm, but never hot. It’s small and convenient to carry, fits in a jacket pocket or a backpack pocket quite easily as it’s remarkably thin.
Can’t fault it.
Super fast and easy to use
I’d previously purchased a cheaper SSD with very disappointing results. Very hit and miss loading and very slow file transfer. But with this sandisc SSD it’s incredibly easy to use and easy file uploading. I can highly recommend this product.
Small, practical but overheating
This SSD is great and is smaller than it looks in the pictures. Which is what you want. No issues but I wouldn’t recommend using preinstalled software that comes with it. If you do you make sure you learn how it works first.
It is also overheating when transferring large amounts of data for a while. I don’t know if that’s a problem or not but it could be if SSD is covered and not cooled down. When you touch it it is actually hot but you can still hold it without getting burned. I’m sure SanDisk know what they are doing and it is not a real threat to the device.
Excellent SSD’s
Brilliant! I’ve got about 20 of them now. Never once had an issue or failure!
Highly recommended.
Fast, rugged, sleek looking
What’s not to like? Works well with my Mac. Use it to manage and backup my Mac Photo Library. Speed is excellent. It does get warm under load, but that’s to be expected. Wish the provided cable was slightly longer, but that’s being petty.
I was a little worried given this did seem to be a little cheap and then I remembered that before Christmas the 1TB version was about 85 so this was maybe a good price point. It certainly does what I need it but truth will be in the pudding as I am planning on using it for DJing this very night of writing this review! It works fine in my Pioneer equipment so here’s hoping it does on some other different Pioneer equipme
Small and powerfull
A small and fast 1Tb SSD. It comes with password protection using 128-bit AES encryption, though for many this can simply complicate things – but its there if you want it!
Not bad for the price [99] and would certainly buy another. Can’t comment on how reliable it is for the long term, but suffice to say it is one of several back-up devices I possess.
My main reason for buying this 1TB ssd was for when I travel and and have lots of camera footage to backup from my shoots.
Portability was a big factor, and hoping it would work with iphone (since there isn’t a lot of info on it)
The ssd itself works well however max transfer speed I’ve seen so far is approx 270 MB/S on magicbook pro using default hardware, nonetheless faster than my other HDD’s. I have noticed it heat up a lot in use, more than the 500gb version. In terms of wire / usb-c port connection, it feels a little flimsy and weak. The ssd has a front patterned surface and a rubber back both of which seem to attract dust.
Now onto iphone connection…I have tried both the 1TB and 500GB versions (with the supplied usb-c to usb adapter), both work with iphone (12 mini) via a genuine Apple Lightning to USB 3 Camera Adapter (make sure adapter is original as fake / defective wires have given me an unpredictable intermittent connection). In my experience the 1TB ssd loaded faster than 500GB on iphone.
Now Iphone allows you to view ssd contents BUT as soon you start saving iphone files onto it or tinkering with the ssd’s data you get the infamous ‘This accessory requires too much power’ sign. Even if you re-connect the ssd, once the sign appears once it keeps coming back. What worked to reverse it for me was actually connecting it to a laptop and deleting the iphone files saved on the ssd or the folders where data was altered. Another option is to scan for errors (whilst plugged into the computer), even if there are no errors I found that often the ssd starts working without needing ‘extra power’. Another option to try, this has given mixed results tbh is to connect the ssd to iphone whilst it is switched off then turn it back on and see if the sign reappears.
If you definitely want 2-way iphone-ssd use then you will need a power hub to power the hardrive (and also bypass the ‘…requires too much power’ message, or if none of the above options work to get rid of the message). I bought the ‘…RSHTECH 5 Port USB 3 Hub with 4 USB 3.0 Data Port + 1 Fast Charging Port Portable USB Splitter with 12V/2A…’ because it provided more power i.e 24W compared to similarly priced 5-port power hubs – so far so good! As a bonus iphone was able to read both ssds (1TB + 500gb) at once when plugged into the power hub.
In terms of folder load time there was no difference for me using a power hub vs none. I didn’t notice a difference in performance or predictability between an old iphone lightning cable vs latest lightning to usb-c cable. I have tried iphone (with ssd connected) plugged into a usb wall socket vs plugged into an apple 30w adapter, again no obv difference.
Another point to mention, with big folders around 90gb (raw files/4k videos) my iphone struggled to read the content despite loading for 20+ mins? The successful cut off for me has been around 65gb folder size max, anything larger definitely gets divided into smaller folders. I did notice some large 4k videos load slowly and freeze midway, but the ssd did let me save them directly on my iphone despite this so was able to view them better that way.
My Sandisk ssd-iphone experience so far (in summary):
Option 1 – viewing/saving ssd content on iphone -> no power hub required
Option 2 – deleting/altering ssd content and/or saving iphone content onto ssd -> power hub required
Hope that helps, I struggled A LOT to find info on iphone sandisk ssd connection so thought I’d share all of my recent findings.
On a sep note – the ssds worked absolutely fine with ipad Air 4th gen utilising it’s usb-c port so no adapter required. Literally a case of plug and play – and definitely a lot faster than on iphone.
