This 2.5'' to 3.5'' hard drive adapter lets you install a 2.5'' SATA or SAS hard drive (HDD) or solid-state drive (SSD) into an internal or external 3.5'' drive bay, using standard drive-mounting holes.

Convert a 2.5'' drive into a 3.5'' drive
The 2.5'' to 3.5'' hard drive bay adapter lets you install a newer, higher performance drive such as an SSD into a legacy system that may only support a 3.5'' hard drive. It provides a cost-efficient way to enhance storage performance and reliability without expensive upgrades to core IT systems. It's also ideal for system administrators who want to build a system that takes advantage of the increased performance of a 2.5'' HDD/SSD.

To utilize the full speed potential of your SATA/SAS drive, the adapter supports transfer speeds up to 6Gbps.
Easy and flexible installation
You can install the adapter into a desktop, server, storage-array, hot-swap bay, and drive drawer. It offers permanent installation in a 3.5'' drive bay with standard mounting holes. When the adapter is installed, you simply slide a 2.5'' HDD/SSD into the adapter enclosure, with no tools required. 

The adapter is suitable for drives with a height of up to 15 mm. Virtually any 2.5'' SATA/SAS drive can be made to look and function like a 3.5'' drive.

Identify and track your drives
The adapter includes a label you can use to track and record information about the installed drive.

The 25SATSAS35HD is backed by a StarTech.com 2-year warranty and free lifetime technical support.
