2.5 to 3.5 SATA SAS Adapter

The StarTech 25SATSAS35HD converts a 2.5in SATA or SAS drive into a 3.5in form factor so it fits a standard desktop bay or external enclosure. It suits builders and IT staff who need to reuse laptop or enterprise drives in a tower chassis without a dedicated 2.5in mount.

Capacity and Headroom

The adapter accepts one 2.5in HDD or SSD up to 15mm in height, covering 7mm, 9.5mm and 12.5mm models. It supports SATA I, II and III at up to 6.0Gbps and SAS revision I and II at 3.0 and 6.0Gbps, so the drive interface does not become a bottleneck.

Thermals Noise and Power

No fan is included; cooling relies on the host chassis airflow passing over the metal frame. The passive design adds no audible noise and draws no power of its own, leaving the drive's own thermal profile unchanged in normal use.

Questions about this item

Will my 2.5" SATA III SSD fit in this adapter alongside the existing 3.5" drives in my server?

Yes, the adapter accepts 2.5" SATA and SAS drives up to 15 mm in height and installs in any standard internal or external 3.5" bay using the included mounting hardware.

How can I verify the adapter is passing data at the full 6.0 Gbps rate after installation?

Check the drive's reported link speed in your OS disk utility or BIOS; it should show SATA III or SAS 6.0 Gbps when a compatible drive is seated in the tool-less tray.

Does the package include the screws and cables needed to mount and connect the adapter in a 3.5" bay?

The box contains the adapter, a set of mounting screws for the 3.5" bay, and a quick-start guide; you will need to supply your own SATA or SAS data and power cables.
