    The 2 TB Sandisk SSD's are solid and long lasting. This is the third 4TB Sandisk SSD I have purchased. After only two weeks of use it started disconnecting from the computer while in use. This has become more frequent until now I no longer trust it. I have replaced it with one made by Samsung. The 2nd one has also started dropping off. Yikes!

      We're sorry to hear about the connection issue you experienced. In many cases, frequent disconnecting can be related to the USB port or cable, so trying a different port or cable can help isolate the cause. If the issue continues, please get in touch with the support team for further assistance by opening a ticket at (https://support-en.sandisk.com/app/askweb) SanDiskConnections

    I'm a pro video editor. At the moment I'm using a M1 Max MacbookPro as my primary workstation. This small SSD has essentially replaced my old big clunky RAID! It's fast, been reliable for 7 months (so far), and fits in my pocket. Only negative is that when traveling I have to make sure not to lose it! (I actually hook it inside my laptop bag when on the go).

    Has helped streamline my photography workflow to upload photos from memory card to SDD. Is blazing fast to browse/organize and edit off of. I like that it has a rubberized exterior layer. Seems like it holds up well to jostles and being thrown around in a camera bag w/ no problem. Nice that it also included a USB-C data transfer cable as well as a USB-C to USB-A adapter. Overall satisfied with my purchase.

    This little unit serves my needs perfectly. I require a lot of external storage and a secondary drive from which I can run apps on my 256 GB Mac Mini M1. This and a couple others I now utilize have completely replaced external hard disk drives in my system. And, if needed to access files on these drives away from home on my 11" iPad Pro M1, a quick eject and I'm on my way. A perfect solution for me!
