Triple Bay 2.5 SAS/SATA Rack

The ICY DOCK ToughArmor MB993SK-B fits three 2.5 inch SATA or SAS drives into a single external 3.5 drive bay. It supports drive heights from 5mm to 7mm and accepts both HDDs and SSDs. This mobile rack is built for servers or workstations that need hot-swap density in a compact form factor.

Host Interface and Power Check

Verify the system provides a SAS host connection if SAS drives are used, because a single SAS channel is required for SAS operation. The rack runs from one floppy 4-pin power connector and delivers SATA 6Gbps or SAS 3.0 12Gbps speeds. It is backward compatible with SATA 3Gbps drives and hosts.

Sustained Load Behaviour

The removable tray system allows individual drive replacement without powering down the enclosure during continuous operation. Drives stay secured in metal trays that act as heatsinks, helping maintain temperature during extended read and write cycles. The single-channel design means total bandwidth is shared across all three bays under heavy simultaneous workloads.

Questions about this item

Does the ToughArmor MB993SK-B include drive trays or must they be purchased separately?

The unit ships with three removable trays that hold 2.5 SATA or SAS drives from 5mm to 7mm thick, so no extra trays are required.

Should I choose a SAS or SATA drive for the 6Gbps and 12Gbps speed ratings?

SATA drives run at up to 6Gbps on any SATA host; SAS drives need a SAS controller and will operate at up to 12Gbps on a single SAS channel.

What does the 12Gbps figure mean when the rack is installed in a live server?

With a SAS host connected, each drive can transfer at up to 12Gbps over the single SAS channel; SATA drives are limited to 6Gbps.
