Customer Ratings & Reviews

Worked well until it didn't. Dead after nine months of photo library backup duty.

after transferring back up files to this external ssd, this device was not accessible. Was able to recognize the device on multiple computers, but was unable to access the drive. looked at manufacturer's website and it appears that others experience same issue.

I've had it less than a year and been forced to reformat it twice. It will eventually just stop showing up on your computer and you'll have to waste an hour of your precious time trying to figure out why it's a piece of trash. Garbage, avoid at all costs

The included instructions were very confusing and even their Customer Service could not help. I had to return it as I could not get it to work.

This Sandisk solid State storage device was faulty, came to know later as i was getting few of my files not copied. From my experience it is having bad sectors for which it hangs often & loses valuable data (video/audio) Returning window was short so unable to return. I am having 3 more such device taken online & all are performing good Had a bad experience with most products purchased in Best Buy North Irving center which is now closed also.

After 1 year using it, it suddenly stopped working and I can’t access to my files anymore :(

Very nice form factor and quick. Unfortunately, it stopped working about the end of the 2nd month of use. I would not recommend purchasing.

Absolute dog water. No software support for this product. Skip it.

Product failed after two years of use. As a primary back up, that was not acceptable. Data recovery services cost $400 to $600 + shipping. Recommend a more reliable product. After failure, drive shows up as empty.

I have had this drive for 7 months and have not been able to use it. The SanDisk Lock feature I installed at setup without realizing what havoc it would cause. I am unable to remove the utility, and carbonite won't recognize either the disk itself or the virtual disk the utility creates. I have spent countless hours trying to fis the problem. I have a very expensive paper weight.

Overheating, loose files. Support from SanDisk pure.

Ive been stress testing this SSD for the last couple of days and while its to early to speak about long term reliability, I can say its handled everything I threw at it so far. I have been transferring over 100 GB of information at a time and its been done in around 2-3 minutes. Thats crazy fast and I'm not used to that kind of performance. I have also used BlackMagic Disk Speed Test to see just how fast this drive is and through many tests the average read/write speeds have been around 920mbps (that's pretty fast) The other thing I want to point out, is just how small this ssd is! Its sleek and small and can easily be put in your pocket for ultra portability. Sandisk claims it is dust/shock proof as well as having an IP55 rating which hopefully I will never have to test out, because I don't plan on using this ssd around water, but its good to know =) The only con so far I can talk about is that when using this ssd with music production software, it has gotten pretty warm, almost on the hot side. This has happened especially when constant read/write actions are being performed. Overall I think this SSD is awesome and I'm excited to use it everyday.

Wow, this thing is impressively awful for an external drive! I'm a computer engineer and struggled to let it write multiple different files. It only ever let me write to it once at a time. If I wanted to write more files the next time it claimed the storage space was full and needed to be wiped each time. Absolutely unusable and not recommended unless you prefer saving data like a drunk gambling with dice.

Crashed already when using it as a photo backup for Mylio photos organizer. Won’t even mount so can’t start over.

The portable hard drive stopped working after a year. Would not reccomend.

I used to record audio to 7200 rpm external hard drives, but for the last 5 years, I've used internal Mac drives because they're blazingly fast. Every time I upgraded Macs, I always bit the bullet and shelled out for the extra HD space. So expensive. Those days are gone! I transferred 80gb of files to this in less than three minutes. I opened large audio projects at higher sample rates, and performance was indistinguishable from that of my internal drive. I'm tempted to go back and get another while they're on sale. Also points for ZERO configuration/formatting. I connected it and started dragging files to it...no permissions errors/passwords. It does run a little warm!

It’s interesting what can happen when you don’t visit a particular technology for a few years. External Solid State Drives have come a long way in a short period of time. I am so impressed by this drive it made me think about the first external hard drive I ever bought some 30 plus years ago. If my math is right (it usually is) this drive is apprx 1/150th the size, has 100,000 times the storage capacity and about 1/3 the price lol. But enough with the trip down memory lane. I love this drive. It’s small, fast, feels well built, quiet and priced right. It’s amazing. I’m using it to build a library of my favorite movies. I may get a 2nd one just to use as a backup to all my files. I usually like to say a little more when I leave a review but what more is there to say? This drive is absolutely fantastic. I would give it 6 stars if I could and I would absolutely recommend it to a friend.

This is great and exactly what I needed for my weekend photography outings. I’ve been overloading my phone lately copying my RAW files to my phone for a little editing and this is perfect for off loading my phone halfway through the day just to clean things up a bit. Getting cold here and don’t really want to be lugging my laptop around all the time. Using my phone as a go between is working fine. Love having all this extra storage space now. Transfer speeds are fantastic although I never maxed out the specs. I moved a 60GB folder of RAW and JPG files from my PC to it in about 6 minutes but I was forced to use the USB-A adapter so I was limited by that. The real speeds show up when using the USB-C direct with 3.2 specs. Looks and feels pretty rugged and a great size to just throw in your pocket whenever you’re heading out.

The SanDisk - Extreme 1TB External is a super fast and portable NVMe Solid State Drive. SanDisk has combined a lightweight and durable hard drive with blazing fast NVMe speed. This is a huge upgrade compared to previous USB 3.0 External Hard Drives. This hard drive is solid enough I feel like I can take it with me and not worry about damaging it anywhere I go. I am a professional photographer so I always need to have an external with me when traveling or editing. I am very impressed by the read write speed of the drive and if you had USB-C it really takes advantage of that higher speed. It's also fast enough to work directly off of using Lightroom and Photoshop which isn't always the case with USB 3.0 Drives. All in all I highly recommend this drive to anyone who is looking for a fast efficient and portable rugged Hard Drive.

Wont connect to anything if u upgrade your operating system (mac) give it one star because i have to put at least one, save your money find something else
