StarTech.com 4 Bay Aluminum Trayless Hot Swap Mobile Rack Backplane for 3.5in SAS II/SATA III - 6 Gbps HDD

The StarTech HSB4SATSASBA is a versatile, rugged solution designed to maximize storage density while minimizing downtime. This removable four-drive backplane turns three 5.25" bays into a hot-swappable interface for four 3.5" SAS or SATA hard disk drives, delivering flexibility for expanding storage in servers, workstations, or external chassis. Built with aluminum for durability and efficient heat dissipation, it offers broad compatibility with SAS I/II and SATA I/II/III, providing up to 6 Gbps per channel. Whether you’re expanding a data center, upgrading an editing workstation, or building a compacte NAS, this trayless backplane makes drive installation, maintenance, and upgrades faster, safer, and more cost-effective. With hot-swap support and a simple, trayless design, you can swap drives without powering down your system in many configurations, reducing maintenance windows and improving uptime. The backplane is designed to be swapped in and out of compatible enclosures, enabling you to refresh storage capacity without replacing the entire chassis.

• The four-drive, trayless backplane enables rapid hot-swapping for up to four 3.5" SAS or SATA hard drives, streamlining maintenance in busy servers or editing workstations while minimizing downtime.
• Trayless design eliminates drive trays and associated screws, slashing the time required to insert or remove drives and improving reliability by reducing moving parts inside the drive path; ideal for environments that demand fast drive changes.
• Constructed from durable aluminum, the backplane provides strong mechanical support and superior heat dissipation, helping to maintain drive performance and extend drive life under demanding workloads.
• Supports a broad range of drive interfaces—SATA I/II/III and SAS I/II—with a combined capability of up to 6 Gbps per channel, ensuring compatibility with current and legacy storage solutions and enabling high-speed data transfer.
• Designed to fit into standard 5.25" drive bays by using three bays to host four 3.5" drives, offering a practical upgrade path for servers, workstations, and storage enclosures without major chassis modifications.

how to install StarTech.com 4 Bay Aluminum Trayless Hot Swap Mobile Rack Backplane for 3.5in SAS II/SATA III - 6 Gbps HDD

• Power down the host system and disconnect from power to prevent any electrical damage during installation.
• Open the chassis and prepare three 5.25" bays where the backplane will be mounted; ensure that there is clear access to data and power pathways for the backplane.
• Remove any existing blanks or drives from the designated 5.25" bays, and align the HSB4SATSASBA backplane with the chassis mounting points so it sits flush against the front of the enclosure.
• Secure the backplane to the chassis using the appropriate mounting screws or rails specified by your enclosure’s design. Confirm that the backplane is firmly seated and that no cables are pinched.
• Connect data cables from your SAS/SATA controller or motherboard to the backplane’s data interface, and attach power cables to the backplane’s power input if required by your chassis or backplane model. Route cables cleanly to maintain airflow and avoid interference with fans or other components.
• Insert your 3.5" SAS or SATA drives into the four hot-swap bays. The trayless design allows direct drive placement without removable trays; ensure drives are fully seated and, if the backplane provides any retention mechanism, secure the drives as directed.
• Power on the system and enter your operating system or RAID controller configuration utility. Initialize the new drives, configure arrays as needed, and verify that all four drives are detected by the controller and reporting healthy SMART status (where applicable).
• Test hot-swap functionality by safely removing and replacing a drive in a controlled test scenario (where supported by your chassis and controller) to confirm that the backplane responds correctly and that the host recognizes changes without a full system reboot.

Frequently asked questions

• Q: What drives does this backplane support? A: It supports 3.5" SATA and SAS hard disk drives, up to four drives, with hot-swap capability and a trayless design for quick drive changes.
