Single-drive 2.5" to 3.5" mobile rack

The ICY DOCK MB991IK-B is a full-metal mobile rack that fits one 2.5" SATA or SAS hard drive or SSD into a single 3.5" device bay. It supports SATA I, II and III as well as SAS 2.0, delivering transfer rates up to 6 Gb/s depending on the drive used. A two-segment key lock secures the drive and the tray uses a 15-pin direct connection for insertion and removal. The unit is designed for systems that need hot-swap capability in a rugged enclosure.

Suited for single-drive hot-swap in tight bays

This rack serves builders who need one removable 2.5" drive in a 3.5" bay, such as in medical, military, media-server, IPC, HTPC or all-in-one systems. It is not for users who require space for more than one drive in the same bay. It is not for installations that cannot accommodate a 3.25" bay opening. It is not for environments where a plastic or tool-less tray is preferred over a locked metal design.

SAS dual-channel support via dual 7-pin SATA host

The specification that decides fit is the dual 7-pin SATA host connection enabling SAS dual-channel operation. If the host backplane or controller provides only a single SATA port, the second SAS channel will not be usable. Verify that your system can connect both 7-pin SATA cables before purchasing.

Questions about this item

What are the exact bay and drive dimensions for the MB991IK-B?

The unit fits a single 2.5" SATA or SAS drive into one standard 3.5" (3.25") front-accessible bay.

Which installation step is most often missed with the 15-pin direct connection?

Align the 7-pin SATA and 15-pin power connectors on the tray with the backplane before sliding the drive in; forcing it without alignment bends pins.

When should the metal tray or key lock be replaced on this rack?

Replace the tray if its guide rails bend or the 15-pin contacts wear, and replace the lock cylinder if the two-segment key no longer turns smoothly.
