USB 3.0 Dual 3.5in SATA III Hard Drive RAID
Enclosure with Fast Charge USB Hub & UASP
Product ID: S352BU33HR
The S352BU33HR 2-Bay RAID Enclosure lets you build an external RAID array using two 3.5” SATA hard
drives, and add it to your computer through USB 3.0.
For optimal performance from your SATA III drives, the external RAID enclosure supports a UASP-enabled
USB 3.0 host connection, which performs up to 70% faster than conventional USB 3.0 when paired with a
UASP compatible host controller. (See UASP testing results below for more detail).
The RAID enclosure also lets you connect additional USB 3.0 devices to your computer, through an
integrated 2-port USB 3.0 hub conveniently mounted on the front of the enclosure. The easy-to-reach hub
also has fast charging capabilities, so you can charge your iPad, smartphone or other mobile devices as
quickly as you would through a direct wall outlet connection.
To help maintain safe operating temperatures for your hard drives, the 2-drive enclosure features a built-
in cooling fan to ensure proper air circulation and prevent your SATA drives from over-heating.

The enclosure features an integrated hardware RAID controller, which gives you the options you need to
set up the array that best suits your storage application, including JBOD, Spanning, RAID 0, and RAID 1.
To ensure compatibility with your computer system, the S352BU33HR supports all of the leading
operating systems, including: Microsoft Windows® (8/7/Vista/XP/Server 2008/Server 2003), Apple® OSX
(10.9/10.8/10.7/10.6), Linux, and Google Chrome OS™.
The S352BU33HR is backed by a StarTech.com 2-year warranty and free lifetime technical support.
Improved Performance with UASP
UASP is supported in Windows 8, Mac OSX (10.8 or above), and Linux. In testing, UASP performs with a
70% faster read speed and 40% faster write speed over traditional USB 3.0 at peak performance.
At the same peak in testing UASP also shows an
80% reduction in required processor resources.
Testing results were obtained using an Intel® Ivy
Bridge system, a UASP-enabled StarTech.com
Enclosure, and a SATA III solid state drive.
