Designed to fit in Olmaster SATA SSD rack - refer pic.
Mount all your 2.5" SSD's and just hot-swap into and out of the Olmaster.
Attach with M3 x 4mm screws
Hint - you may have to set BIOS to allow hot swap of SATA devices.

This holder still allows you to plug your SSD into USB Docking stations and USB leads.
