I bought two for my workbench computer so I can switch operating systems and test drives on my workbench computer. The drives change out real easy with these trayless bays. There was previously a tray SATA bay and it was a hassle changing the drives out, this is so much easier.
Poorly designed product of low quality. The front bezel is partially made of alloy but has a cheap plastic extension fastened by wimpy screws attached to plastic. Bad design.
Great to change OSs
No trays to remount
Reboot and change drives
Want Windows, pop in a drive
Want Linux, pop In a version
Want a storage disk, pop it in
