    Exactly what I needed as a backup. I DJ a lot and always have 3-4 backup USB hard drives. At first, my DJ software did not recognize my music folders or (or vice -versa). A folder with 700 songs would take over a minute to appear. The larger the folder, the longer it took. I almost returned the drive, as I was told as well as read that SSD’s were smoking fast. After a few reboots and file scans using Virtual DJ, all is working well. I suggest a case to be in your budget as this thing is small. You could easily lose or misplace it.

    Holy crappy this thing is fast. Use the cable it came with (or a carefully selected longer one if you’re like me and hate short drive cables). I initially used a different, quality cable and was disappointed in the speed. Plugged in the cable from the box and re-transferred 2 hours worth in roughly 3 minutes. Also the drive is so small and light I thought I got an empty box. LOVE this drive. It’s a 4TB miracle lol.

    Compared to the backup drives of the past (And I've got quite a few) .. this is not only TINY in size, but it is just as good at backup as the older ones (and faster to do so overall). I tend to use the 4tb Drives for when I travel and enjoy my photography hobby -- that's the reason for this purchase. I also use it to hold such as recipes (From cooking schools I attend while traveling - I like to go to places were I can eat and get recipes too learning new techniques), my documents, and other miscellaneous content. (including my backup for my MP3/4 drive music files).

    Lots of storage, fast external SSD with USB-C connectivity. However, if you plan on using it on a Macintosh, be aware that (as of Dec, 2021), it arrives formatted as ExFAT. And for software reasons related to Sandisk and/or Mac OS, it cannot be reformatted to HFS+/APS until these software issues are addressed by Apple/Sandisk. So, if you need HFS+/APS (for Time Machine, etc), I would hold off buying one until this issue is fixed.

    Monterey Problem Solved. Feel free to purchase.

    I just want to clear the air for MAC users. I purchased this product in March 2022 after contacting Apple and they assured me that it works with Monterey. There were glitches in the beginning, but that was quickly solved. I set it up APFS, hooked it in to the thunderbolt connection on a iMAC 27" and it works fine while running MONTEREY. The reason for my purchase was the PHOTO speed. With a Seagate which I love, it could not index and search. Now that Apple has come up with Photo identification this is a whole new world. Type a search for Bear and it separated, Koala Bear, Panda Bear, Teddy Bear and put the Black, Brown, Grizzly and Polar Bears together. It did not find a frog, but using reptile search there they were.
