4 Bay Aluminum Trayless Hot Swap Mobile Rack
Backplane for 3.5in SAS II/SATA III - 6 Gbps HDD
Product ID: HSB4SATSASBA
The HSB4SATSASBA Removable 4-drive Backplane makes inserting and removing drives fast and easy, by
turning three 5.25" bays into a hot-swappable interface for up to four 3.5” SATA or SAS hard drives
(HDD).
For added versatility, the hot swap bay can interface with SATA I/II/III and SAS I/II hard drives -- an
ideal solution for enterprise system applications.
For a quick and secure method of installing and removing drives, the backplane features ejection levers
and a key-lock design. To help prevent drive failure, the bay provides drive cooling with a built-in fan
and excellent heat dissipation with a vented aluminum enclosure.
The HSB4SATSASBA is backed by a StarTech.com 2-year warranty and free lifetime technical support.
