Deployment / Use Cases
This mobile rack backplane is ideal for expanding storage capacity in systems with available 3.5" drive bays. It enables the installation of two 2.5" SATA drives where space would normally accommodate only a single 3.5" drive, effectively doubling storage potential in the same physical footprint.
Common deployment scenarios include adding SSD storage to desktop workstations for improved performance, creating redundant drive configurations in small servers, or upgrading storage in existing systems without modifying chassis layouts. The hot-swap capability makes it particularly valuable in environments requiring frequent drive changes or maintenance without system downtime.
Desktop Storage Expansion
Add dual 2.5" SSD or HDD storage to desktop computers with available 3.5" drive bays, improving performance or capacity without chassis modification.
Server Drive Management
Implement hot-swappable drive configurations in server environments where drive accessibility and quick replacement are operational requirements.
Physical Profile
The backplane features a black aluminum enclosure designed for internal mounting in standard 3.5" drive bays. Its dimensions of 4" wide x 5.30" deep x 0.90" high ensure compatibility with most desktop and server drive bay configurations. The aluminum construction provides structural rigidity while aiding in heat dissipation from installed drives. The unit includes mounting provisions for secure installation in drive bays.

User Manual
FAQ
How many drives does this backplane support and what size are they?
This backplane supports two 2.5-inch form factor SATA drives. It accommodates both hard disk drives (HDDs) and solid-state drives (SSDs) in the 2.5-inch size standard. The unit does not include any pre-installed drives, allowing you to install your preferred storage devices based on capacity and performance requirements.
What type of drive bay does this unit install into?
The backplane installs into a standard 3.5-inch internal drive bay commonly found in desktop computers, servers, and storage enclosures. It converts a single 3.5-inch bay into dual 2.5-inch drive capacity, maximizing storage density without requiring additional rack space or chassis modification.
What does 'trayless design' mean for this product?
The trayless design means drives install directly into the backplane without requiring separate drive trays or enclosures. This eliminates the need to mount drives into trays before installation, simplifying the process of adding or replacing drives. Drives slide directly into the backplane's drive bays and secure in place, reducing component count and streamlining maintenance.
Is this backplane hot-swap compatible?
Yes, this backplane is hot-swap compatible, allowing you to insert or remove drives while the system remains powered on and operational. This capability is particularly valuable in server environments or workstations where drive changes are needed without system downtime. The backplane supports SATA hot-swap functionality for both HDD and SSD drives.
What SATA interfaces does this backplane support?
The backplane supports SATA revision I (1.5 Gbps), revision II (3.0 Gbps), and revision III (6.0 Gbps) interfaces through its SATA/600 host and drive connections. This ensures compatibility with a wide range of SATA drives from older 1.5 Gbps models to modern 6.0 Gbps SSDs. The unit maintains proper signaling for each SATA generation.
What cables and accessories are included with the backplane?
The package includes all necessary cables for installation: two LP4 to SATA and LED adapter cables, one 15-pin SATA power and LED Y cable, and two 7-pin SATA data cables. Additional accessories include two hard drive protector films for drive bottom protection, a comprehensive screw kit for mounting, and an instruction manual. These components provide complete installation capability without requiring separate purchases.
