ICY DOCK

ICY DOCK MB901SPR-B R1 Dual 2.5"/3.5" SATA RAID 1 JBOD 5.25" Bay Hard Drive Adapter

SKU CH-9XK4-2GV6M

Dual 2.5" or 3.5" SATA drive enclosure with hardware RAID 1 and JBOD fits two 5.25" bays

  • Hardware RAID 1 mirroring protects data automatically
  • JMS562 chipset handles RAID without using system resources
  • Fits two 2.5 or 3.5 SATA drives in a 5.25 bay
  • Hot-swap trays let you replace a failed drive without shutdown
  • LED indicators show power, access, fail and rebuild status

Dual-bay RAID enclosure for 2.5"

The ICY DOCK MB901SPR-B R1 fits two 2.5-inch SSDs or 3.5-inch SATA hard drives into a pair of standard 5.25-inch optical bays. It uses a built-in JMS562 hardware RAID chipset to provide RAID 1 mirroring or JBOD spanning without consuming host CPU cycles. Hot-swap trays allow drive replacement while the system stays powered on, making it suited for file servers and industrial workstations that need continuous uptime.

Anti-vibration design with locking power connectors

Anti-Vibration Technology dampens mechanical noise and protects drives from environmental shock during normal operation. The unit accepts standard SATA data cables and 15-pin SATA power connectors that feature a locking latch to prevent accidental disconnection. Status LEDs on the front panel show drive power, access activity, drive failure and RAID 1 rebuild progress at a glance.

Hardware RAID offload maintains throughput under

Because the JMS562 controller handles all mirroring calculations on-board, sustained write workloads do not increase host processor utilisation the way software RAID does. The enclosure supports the full 6 Gbps SATA link speed for each drive, so extended rebuilds or continuous streaming reads proceed without throttling. Hot-swap capability means a degraded array can be repaired without scheduling downtime.

Questions about this item

How do I install the MB901SPR-B R1 into a 5.25" bay and which step is often missed?

Slide the enclosure into two adjacent 5.25" bays, secure it with screws, connect the SATA data cable and 15-pin power cable with locking latch to each tray, then set the RAID mode switch before powering on; the step most often missed is configuring the RAID 1 or JBOD mode via the hardware switch prior to first boot.

What maintenance will the MB901SPR-B R1 need over time?

The removable trays support hot-swap replacement of a failed 2.5" or 3.5" SATA drive without shutting down; periodically check the RAID status LEDs for drive power, access, fail or rebuild indication and clean dust from the Anti-Vibration Technology mounts to maintain cooling efficiency.

What limit appears first during sustained heavy writes on the MB901SPR-B R1?

The JMS562 hardware RAID chipset caps the array at 6 Gbps SATA throughput, so sustained sequential writes will hit that interface ceiling before the mechanical drives or the chipset thermal throttle become the bottleneck.
