Best price for original new item. It took longer than promised delivery - arrived 1 day late.

A good choice for the price.

It is the lowest of the Sandisk brand (in price) but so far, so good. Put all my files in it and works fine.

Great!

I'd been needing one of these for a while now and I finally got around to buying it. I use it to run an iMac and so far it has been great. I also love the vibrant colors of the device, and the sleekness of it.

Cables MATTER!

Do not buy a USB-C to USB-C charging cable for this. Most of those have fine print saying they only work at 480Mbits/second. The USB-C to USB-A cable that comes with it is rated at 5Gbits/second and almost keeps up to the SSD. I bought a 10Gbit/sec USB-C to USB-C cable for my macbook and get the full speed. Also if you use the USB-A make sure it is fully inserted (see my test results below with 8GB transfer) Connection | Link | SpeedWrite (8GB) | Read (8GB) USB-A partially inserted | USB 2.0 (480 Mb/s) | ~33 MB/s. | ~33 MB/s USB-A fully inserted. | USB 3.1 Gen 1 (5 Gb/s) | 258 MB/s | 407 MB/s USB-C to USB-C. | USB 3.1 Gen 2 (10 Gb/s) | 366 MB/s | 921 MB/s

Connecting to MacBook Air is hit or miss

Do not buy if you want to use this on a MacBook Air. The first drive I purchased would only connect to the computer intermittently. I have tried this on multiple Mac's with the same result. I sent this back and received a replacement drive and still have the same issue. Returning for another replacement wouldn't make sense if I still have the same issue.

We're sorry to hear about your experience. Please ensure it is firmly connected and try a different port, cable or computer to help isolate the issue. You may also try formatting the drive using these steps: https://support-en.sandisk.com/app/answers/detailweb/a_id/20821 (please ensure to backup your data before formatting since it is a data-destructive process). If the issue persists, please contact us at: https://support-en.sandisk.com/app/askweb and we'll assist you further.

Extremely slow write/read speeds!

There's this thing. It's called FALSE ADVERTISING. And it certainly applies here. I unfortunately bought two of these 2TB drives and when I eventually got around to using them I noticed they seemed really slow. I checked the formatting, ran BlackMagic tests and I am getting aprox 125-165 mb/s write speeds. This is using the supplied cable, plugged directly into the first port on a new Mac Mini m2. The drive is formatted correctly, using APFS, has barely been used. I just can't believe it! So disappointed with these.

Rubbish, doesn't work on Mac

I bought the 1 TB version and – surprise – it can't be formatted on a Mac. The "firmware issue that presents itself in very limited situations" is apparently a lie, the internet is full of reports and there is no solution by Sandisk/WD, only excuses. There is a firmware update that works on Windows and anyway, this model is "officially" not affected by problems. Don't bother asking for a serial number, it's officially not affected so I guess there will never be a solution. I will have this replaced by the shop and buy from a more reliable manufacturer. I will warn other people to buy Sandisk products.
