The black 5.25” USM Removable Storage Bay with 2.5” SATA USM/USB 3.0 Hard Drive Enclosure from StarTech turns a 5.25" front computer bay into a hot-swappable USM (Universal Storage Module) interface. You can connect a 2.5" SATA HDD or SSD to this USM interface using the included USM enclosure. USM is a portable drive standard that interfaces with SATA and enables you to hot swap drives between multiple host devices, such as PCs, notebooks, DVRs, and many others. Both the bay and enclosure are compatible with Seagate GoFlex and other USM interface devices, and support SATA III transfer speeds up to 6 Gb/s.

The USM removable hard drive bay interfaces with SATA, and can be mounted into any 5.25" front bay to provide a hot-swappable mobile rack. The bay features push-button ejection, allowing drives to be easily installed and removed from the computer system. This device provides a convenient method of creating backups that can be removed for safe keeping, archiving, or external portable access.

The enclosure can also be connected externally to non-USM host devices via USB thanks to the included USM to USB 3.0 adapter. When connected to a UASP (USB Attached SCSI Protocol) compatible host controller, the enclosure is capable of up to 70% faster read speed than conventional USB 3.0, making it easy to take advantage of the full speed potential of your SATA III hard drives.

The storage bay supports most operating systems, including Microsoft Windows (8/7/Vista/XP/Server 2008/Server 2003), Apple OSX (10.9/10.8/10.7/10.6), Linux, and Google Chrome OS. It can also be used with theS2510U33USM 2.5" USM SATA Hard Drive Enclosure (not included), which offers the option to swap multiple drives in and out of the main computer as needed.

Note: UASP is supported in Windows 8, Mac (OSX 10.8 or above), and Linux. In testing UASP performs with a 70% faster read speed and 40% faster write speed over traditional USB 3.0 at peak performance. Testing results were obtained using an Intel Ivy Bridge system, a UASP enabled StarTech enclosure, and a SATA III solid state drive. At the same peak in testing, UASP also shows an 80% reduction in required processor resources.
