Connect 2.5" SATA Drives via USB 3.1 Gen 2

This ultra-portable adapter cable connects a 2.5" SATA SSD or HDD to a computer using a USB 3.1 Gen 2 Type-A port. It delivers up to 10 Gbps bandwidth and supports SATA III speeds of 6 Gbps. The ASMedia ASM1351 chipset enables UASP for improved transfer performance. Power is drawn directly from the USB port with no external supply required.

Suits Quick Drive Access, Not 3.5" Desktop Drives

The cable-style design makes it practical for technicians and users who need fast, tool-free access to 2.5" drives for data recovery, imaging or backups. It is backward compatible with USB 3.0, 2.0 and 1.x hosts. Builders needing to power 3.5" desktop drives should look elsewhere because this adapter provides no separate power input for the higher spin-up current those drives require.

2.5-Inch Cable Length Limits Placement

The integrated cable measures 2.5 inches end to end, so the drive sits immediately next to the host port. This keeps the setup compact for laptop use but prevents placing the drive at a distance or routing the cable behind a desktop chassis. Verify that your work area can accommodate this fixed reach before purchase.

Questions about this item

Does the USB 3.1 Gen 2 (10 Gbps) interface cap SATA III drive speeds in practice?

The adapter runs at USB 3.1 Gen 2 10 Gbps while SATA III tops out at 6 Gbps, so the SATA drive remains the limiting factor.

What physical space does the 2.5" cable need to fit a 2.5" SATA drive?

The 2.5" cable ends in a 7+15 pin SATA receptacle that accepts standard 2.5" SATA SSDs or HDDs.

How is the adapter installed and what step is often missed?

Plug the USB Type-A male end into the host, attach the SATA combo connector to the drive, and ensure the host port can supply enough bus power for the 2.5" drive.
