I've used OWC drive bays for years and this one solved a need for a reliable and expandable RAID backup. It's really helpful that any size drive will work in these bays, 2.5 or 3.5 and can used together. Also, it's QUIET.

I wanted a box to hold 4 drives, in RAID 0, as a staging site for pushing an off-site backup of my NAS to a cloud provider. While not the cheapest option, the build quality is superb and the unit has worked flawlessly.
