Introducing the MB153SP-B, a 3-in-2 SATA internal RAID backplane for 3.5 SATA hard drives. This is a lite version of the MB45X series by removing the monitoring features and reducing the overall cost, while keeping the same 3 year warranty and the core tray system for hot swapping and maintenance are kept for the best reliability in the market.Slimmed Down DesignThe MB153SP-B has been redesigned to be a lighter module, while maintaining the same level of quality, build, and service you'd expect from an Icy Dock product. While the design has gone through some changes, the space saving design is still established. The backplane module allows up to 3 x 3.5 SATA III hard drives, while only consuming two 5.25 bays. The module has also been redesigned for the type of power connector accepted. 15 pin SATA power is used to provide better accessibility for various host systems.
