StarTech ID: S251SMU33EP

The S251SMU33EP USB 3.0 / eSATAp drive enclosure turns a 2.5in SATA hard drive (HDD) or solid state drive
(SSD) into an external portable hard drive that can connect to any USB or eSATA-enabled computer system.

For fast performance and efficient data transfers when connected through eSATA, the enclosure supports full
SATA III transfer speeds -- up to 6 Gbps. For universal compatibility, the S251SMU33EP can be connected
through USB 3.0 with transfer speeds up 5 Gbps plus support for UASP, which delivers performance up to 70%
faster than conventional USB 3.0 when paired with a UASP-enabled host controller to utilize the full potential of
your SATA III hard drives. See our UASP testing results below for further details.

Designed for maximum portability, the S251SMU33EP doesn't require an external power adapter when
connected to an eSATAp (USB + eSATA combo) host port.

The 2.5in enclosure supports the fastest drive technologies including SATA III (6 Gbps), hybrid drives and solid
state drives (SSD), saving you time by ensuring you're getting the most out of your drive performance.

To ensure compatibility with your computer system, the S251SMU33EP supports all of the leading operating
systems, including: Microsoft Windows®, Apple® OSX, Linux, and Google Chrome OS™.

The S251SMU33EP is backed by a StarTech.com 2-year warranty and free lifetime technical support.
