The ExpressCage MB742SP-B brings dense 2.5 SSD or HDD storage to the floppy 3.5 bay. With the rising popularity of SFF (Small-Form-Factor) systems due to space-savings and lower power usage, a convenient and protective data storage enclosure is necessary to maintain the critical data stored in the system. The ExpressTray MB742TP-B drive caddy supports tool-less drive installation, and it has been designed to hold your drives securely, with an enhanced tool-less drive gripping mechanism, stabilized drive insertion design, and a strengthened single-piece latch. The new metal chassis has all-around air ventilation to keep your drives running cool all day, even under heavy load.
Utilizing the small space of the external 3.5 drive bay (floppy bay), the MB742SP-B is perfect for applications where space is limited. Small-Form-Factor (SFF) PCs, embedded systems, Box PCs, in-vehicle systems, and home servers can all benefit from this dual 2.5 SAS/SATA drive enclosure. The two drives are also in an ideal position to be used in a RAID setup when combined with a RAID card or software RAID solution. A RAID 1 setup can be used to prevent drive failure, and is excellent for sensitive data, or having a backup of your OS drive. A RAID 0 setup is ideal for applications that require high-speeds, such as in a gaming computer or photo/video editing system. Maximize your speed and security while minimizing your space footprint with MB742SP-B.
Innovative New Tray Caddy Design
The ExpressTray MB742TP-B in the MB742SP-B is designed for applications where drive hot-swap is required, while providing security and durability. Grips on the sides of the caddy hold your drives securely, to keep your sensitive data safe.
The unique built-in screws allow for entirely tool-less drive installation and removal, to allow for quick and easy swapping of drives.
