    Solid product, been looking forward to the increased storage in this series. Not too much larger than my 2GB model but double the storage! Durable, sturdy, solid. 9.5 / 10

    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.
