Product Features
Technical Overview
This drive adapter delivers full electrical and mechanical compatibility between 2.5" SATA/SAS drives and 3.5" drive bays. The interface supports SATA/600 (6Gb/s) and Serial Attached SCSI (SAS) connections, maintaining native performance without signal degradation or speed limitations. The adapter preserves the complete feature set of connected drives, including advanced SAS functionality and SATA III throughput.
The physical design incorporates standard 3.5" mounting holes for secure installation in internal drive bays, while the tool-less mechanism for 2.5" drives eliminates the need for additional screws or brackets. The adapter's dimensions (1" H × 4" W × 5.70" D) ensure proper fit within standard 3.5" bay spaces while providing adequate clearance for drive connectors and cables.
Relevant factors for this section include Number of Hard Drives Supported, Number of Hard Drives Installed, Number of Solid State Drive Supported, Number of Total Expansion Bays. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

- Quick-release mechanism
Deployment / Use Cases
This drive adapter serves multiple practical applications in enterprise, small business, and enthusiast computing environments where storage flexibility and backward compatibility are essential.
In server environments, the adapter enables the deployment of high-performance 2.5" SAS SSDs in legacy servers designed primarily for 3.5" drive bays. This allows organizations to upgrade storage performance without replacing entire server chassis or investing in specialized drive cages. For desktop workstations and gaming systems, the adapter provides a cost-effective way to install 2.5" SATA SSDs in cases with abundant 3.5" bays but limited 2.5" mounting options.
Server Storage Upgrades
Deploy modern 2.5" SAS SSDs in existing server racks with 3.5" drive bays to improve performance while maintaining existing infrastructure investments.
Desktop Storage Expansion
Add 2.5" SATA SSDs to desktop systems with available 3.5" bays, enabling faster boot times and application loading without requiring case modifications.
Physical Profile
The adapter features a compact design that fits precisely within standard 3.5" drive bay dimensions while providing adequate space for drive connectors and cable management. The silver and black color scheme blends with most chassis interiors, and the aluminum construction provides structural rigidity while minimizing weight. The tool-less mechanism incorporates secure locking tabs that hold drives firmly in place without vibration or movement during operation.

User Manual
FAQ
What types of drives are compatible with this adapter?
The adapter supports both 2.5" SATA and SAS solid-state drives (SSDs) and hard disk drives (HDDs). It works with SATA I, II, and III standards (up to 6Gb/s) and SAS I and II standards (up to 6Gb/s). The adapter accommodates drives up to 15mm in height, which includes most standard and many thicker enterprise-class drives.
Does this adapter require tools for installation?
The adapter features a tool-less design for installing 2.5" drives. You simply slide the drive into the adapter and secure it using the built-in locking mechanism without needing additional screws or tools. The adapter itself mounts into 3.5" drive bays using standard mounting screws that are typically included with computer cases or available separately.
Can I use this adapter in external drive enclosures?
While the adapter is designed primarily for internal use in standard 3.5" drive bays, it can potentially work in external enclosures that accept internal 3.5" drives. However, compatibility depends on the specific enclosure's design and available space. The adapter's dimensions (1" H × 4" W × 5.70" D) should be verified against the enclosure's internal clearance.
What is the maximum drive height supported?
The adapter supports 2.5" drives up to 15mm in height. This accommodates most standard 2.5" drives (typically 7mm or 9.5mm) as well as many thicker enterprise or high-capacity drives. Before installation, verify your drive's height specification to ensure compatibility with the 15mm maximum clearance.
Does this adapter support both SATA and SAS simultaneously?
The adapter provides physical and electrical compatibility for both SATA and SAS interfaces, but it does not allow simultaneous connection of both interface types to a single host. You connect either a SATA drive or a SAS drive to the adapter, and the adapter preserves the native interface connection to your system's SATA or SAS controller accordingly.
What warranty coverage does this product include?
StarTech.com provides a 2-year limited warranty for this drive adapter. The warranty covers defects in materials and workmanship under normal use. For warranty service or support, you can contact StarTech.com directly with your proof of purchase. The product also complies with environmental regulations including RoHS, WEEE, and REACH standards.
