Silver metal tray holding two 2.5 inch drive carriers for a 5.25 inch bay

ICY DOCK

ICY DOCK ToughArmor RAID MB902SPR-B R1 2.5" SATA drive enclosure for 5.25" bay

SKU CH-NPZE-ZHC48

Holds two 2.5" SATA drives in a 5.25" bay with hardware RAID 1 or JBOD modes and a locking latch for secure connections

  • Product typeEnclosure
  • Supports two 2.5" drives from 5–15 mm height for maximum compatibility
  • Hardware RAID 1 and JBOD modes via JMS562 chipset for redundancy or capacity
  • Fits any standard 5.25" optical bay for quick integration
  • SATA 6 Gbps transfers with locking SATA and power cables for secure links
  • Full-metal rugged build suited for medical, military, server and industrial PCs

Dual 2.5" SATA Drive Enclosure

The ICY DOCK ToughArmor RAID MB902SPR-B R1 fits two 2.5 inch SATA solid-state or hard drives into a single external 5.25 inch optical bay. Drives from 5 mm to 15 mm thick are accepted. A hardware JMS562 chipset manages RAID 1 mirroring or JBOD spanning without software overhead. The enclosure connects through standard SATA data and 15-pin power cables with locking latches.

Builders Needing Redundancy or Simple Expansion

This unit suits system integrators who want hardware RAID 1 protection or a single large JBOD volume inside a standard 5.25 inch bay. Medical, military and industrial PCs benefit from the full-metal construction. It does not suit users who need more than two drives, a smaller form factor, or an interface other than SATA.

Hardware RAID Chipset

The onboard JMS562 controller handles RAID 1 and JBOD modes independently of the host system. This specification decides whether the enclosure meets the requirement for driver-free redundancy or capacity pooling.

Questions about this item

Should I use RAID 1 or JBOD with two 2.5" drives in this enclosure?

RAID 1 mirrors both drives for redundancy, so one failure keeps data safe. JBOD presents them as separate volumes, giving full combined capacity but no protection. Choose RAID 1 for critical data, JBOD for maximum space.

What does the 6 Gbps figure mean when the drives are installed in a PC?

The SATA link runs at up to 6 Gbps. Actual throughput depends on the drives themselves and the host controller, so sustained speeds will match the slower of the two limits.

Does the JMS562 chipset limit the RAID modes or drive count?

The JMS562 handles RAID 1 and JBOD for exactly two 2.5" SATA drives. It does not support other RAID levels or more than two drives in this enclosure.
