Four-bay trayless mobile rack

The StarTech HSB4SATSASBA installs in three 5.25in bays and holds four 3.5in hard drives. It accepts both SATA III and SAS II drives and provides a 70 mm sleeve-bearing fan for active cooling. A built-in key lock secures the drives, and the trayless design allows hot-swap changes without tools. The unit connects through four SATA data and two SATA power receptacles.

Suited for servers and workstations needing

Administrators who want on-site backup or quick drive rotation will benefit from the hot-swap capability and lockable bays. The rack requires three adjacent 5.25in front-panel openings, so compact cases without that space cannot accommodate it. Builders using only 2.5in drives or needing more than four bays should consider a different enclosure.

SATA 6 Gbps and SAS II support

The backplane operates at SATA revision I, II and III speeds up to 6.0 Gbps and supports SAS II through SFF-8482 connectors. This single interface specification determines whether your host controller and drives are compatible with the rack.

Questions about this item

How loud is the built-in 70 mm sleeve-bearing fan when the unit runs all day?

The 70 mm sleeve-bearing fan provides active cooling for the four drives; sleeve bearings typically run quieter than ball bearings at low speed, so noise stays low during continuous operation.

Which cables and host connectors must my system already have to use all four bays?

Your motherboard or controller needs four free SATA 7-pin data ports, and the backplane requires two SATA 15-pin power connectors from your power supply.

Will my older 1.5 Gbps or 3.0 Gbps SATA drives work in this SAS II / SATA III backplane?

Yes — the backplane supports SATA I, II and III (1.5, 3.0 and 6.0 Gbps) as well as SAS II, so legacy SATA drives negotiate down to their native speed and function normally.
