USB-C 10 Gbps SATA adapter

This USB 3.1 Gen 2 cable connects a 2.5" SATA SSD or HDD directly to a USB-C port on a laptop or desktop. It supports SATA I, II and III drives and uses the ASMedia ASM1351 chipset with UASP for improved transfer efficiency. The adapter is bus powered so no external supply is needed. It suits technicians and mobile users who need quick, portable access to bare 2.5" drives.

Replaces docks and enclosures

Unlike bulky drive docks or full enclosures, this 0.06 lb cable adds no extra housing and fits in a laptop bag. The jump is worth it when you swap drives frequently or need to recover data from multiple 2.5" SATA units without mounting hardware. It does not serve 3.5" drives or M.2 devices, and it cannot power a drive that exceeds the host port's current limit.

Limited to 2.5" SATA and USB-C host

The interface tops out at 10 Gbps, so the fastest SATA SSDs will hit the bus ceiling rather than their own media limit. Cable length is fixed at the moulded 0.20" x 1.70" x 1.80" dongle form factor, so reach is minimal and strain relief depends on the host port. No external power input exists, so drives requiring more than the USB-C port can deliver will not spin up.

Questions about this item

Does the USB-C connector on the StarTech USB31CSAT3CB plug directly into a 2.5in SATA drive without an extra power cable?

Yes, the adapter connects directly to a 2.5in SATA SSD or HDD and draws power from the USB 3.1 Gen 2 port, so no separate power supply is needed.

What is the correct order to connect the StarTech USB31CSAT3CB so the drive is recognised?

Attach the SATA end to the 2.5in drive first, then plug the USB-C male connector into the host port; reversing the order can prevent the drive from mounting.

Will the StarTech USB31CSAT3CB need a firmware update for the ASMedia ASM1351 chipset to maintain UASP performance?

The ASM1351 chipset operates with the UASP protocol supported by the host operating system, so no separate firmware updates are required for the adapter itself.
