Customer Ratings & Reviews

Good item. Have not used it yet IT friends say it was a good deal.

Never recommending these drives. I have a 1 TB and the 4TB and they both failed together. A few months ago the drives would not load on my Mac and it turned out to be a SanDisk problem. Their solution is to use a Windows 10 or 11 computer to update the firmware, but not before making sure your files are backed up. That requires a trip to a tech support desk at Best Buy or similar, or calling a friend with said computer. Just read it for yourself on Ars Technica "SanDisk’s silence deafens as high-profile users say Extreme SSDs still broken" or any other google search for this problem will lead you to the many users who have lost files.

These things are a great size and work well, used/compatible with MacBook

Good product and good color but itis too hard and need

This unit is an external SSD storage device. Unit works as intended.

The SanDisk Extreme NVMe SSD has a small size and rugged construction perfect for taking it with you on the go, and fast speeds which make it great for any task you could reasonably throw at it. Backed by the long-trusted SanDisk and Western Digital brands, this unit is a worthy pick for those needing a decent external drive. [ Performance ] During my benchmarks connected to a laptop via USB 3.2 Gen 2 type C port using the included USB-C cable, I maxed out at 978.72 MB/s read speed and 940.03 MB/s write speed with sequential 1MB chunks in CrystalDiskMark, reasonably close to the advertised maximum speeds. In practical file transfer tests between this and another NVMe SSD drive connected to the same computer via M.2 (where the other drive benchmarks faster in all regards), I was getting about 700 MB/s read speeds and 465 MB/s write speeds consistently from/to the SanDisk drive. For stability testing, I recorded many hours of high-resolution, high-bandwidth gameplay videos directly to the drive which went very smoothly with no hiccups. [ Design ] The rubberized body feels very sturdy, and I suspect could endure some significant punishment while protecting the internals from harm. The IP55 rated dust and water resistance, while not amazing, provides enough protection against mishaps to confidently take the unit on the go. There’s no plug/cap for the USB port on the drive, which detracts somewhat from its otherwise rugged design. The ‘carabiner loop’ is a nice touch for some added utility. One of the most unfortunate--and arguably bizarre--design choices is the incredibly short USB-C cable included. While barely sufficient for plugging this drive into a laptop or other small device (tablet, phone, camera, etc.), plugging this drive into a PC with a tower case is almost certainly going to require a much longer cable to avoid unintentional disconnects. There’s no power or activity light, and while not necessarily unusual, it is a feature that some may miss.

The cable to the pc should be longer. Very short and stiff

Extremely fast transfers in large files. Great product.

.Ssd's are always best option for storage, transfer data

It does exactly what I needed it to do. Good quality product.

Meets all my needs for the moment. can’t complain.

I finally bought this fearing my 10-15 year old HDs were going to die on me and take precious family memories with them. I should have known when more often this would suddenly eject itself. But using it so little the thought slipped my mind. Not even 2 years in and this drive is dead. "Insert disk" error on several PCs and devices. Come to learn WD is now being sued because the failures are so common yet ignored by them. These are being heavily discount often. DO NOT fall for it, WD is offloading bad products.

Worked great when i first bought it a year ago. After six months the drive quit. The drive doesnt show on my Apple Mac or Windows 10 PC. I tried a new proven working cable hoping that was the issue, but no luck. Not sure what to do. 

Sandisk/Western Digital is aware of firmware problems with these drives yet they keep them on the market. Do some research, you WILL lose data if you buy this drive. At best, it'll randomly disconnect and reconnect, maybe causing some file corruption. At worst, I'll cause your whole computer to crash and shut down. Others are having the same experience. Manufacturer is in denial. These products should be pulled from the shelves.

It works very well but it apparently cannot be used for another android device after using it on a first android device without reformatting it. Not pleased about that!

Price match was easy. Item arrived 3 days late. Poor shipping; NO packing material in the box. Haven’t yet been able to use because of family issues. Will update once used.

Completely broke after only 1.5 years. There was no warning, no physical damage, nothing. I didn't even carry this with me anywhere. It was just plugged in on my home computer. Out of a sudden its stopped being recognized by any computer. The cable works. Absolute worthless. BestBuy refused to refund my money, since it is outside of the return window. Never did I have an external hard-drive stop working, especially after not even 2 years. I would not recommend this, unless you like loosing all your data. They should have refunded me, because this is unacceptable.

This drive is garbage due to it's Sandisk Unlocker program that is difficult to remove from the drive. It not only takes a lot of trial and error to get my computer to recognize it each time I plug it in, it also literally blocks access to my other drives on my computer. I'm using a 2 year old Dell, somewhat higher end laptop and I'm hardly an amateur when it comes to hardware. The portability function of this drive is also worthless because neither my work PC nor my other desktop will recognize this thing. Don't plan on taking this drive elsewhere if you plan on sharing files.

I was told just take it home plug it in. Well, a few days ago, I called the 800 number because of a warning from WebRoot. Your rep looked at my setup and all was well: desktop hard drive at 90% & ext. At 0%

It still works hence 2 stars, but larger capacity models have serious issues. Sandisk used to be a brand I trusted and Western Digital (who bought them) was in the past a reliable brand. I'm not sure what is happening with the quality of products now but I cannot recommend these brands' products anymore.
