USB 3.0/eSATA Dual 3.5” SATA III Hard Drive External RAID Enclosure w/ UASP and Fan – White
StarTech ID: S3520WU33ER
The S3520WU33ER 2-Bay RAID Enclosure with UASP enables you to build a secure external RAID array with two
3.5” SATA hard drives, connected to your computer through an available USB 3.0 or eSATA port.
For fast performance and efficient data transfers the enclosure supports SATA III transfer speeds -- up to 6
Gbps when connected through eSATA. The versatile RAID enclosure can also be connected through USB 3.0, with
support for UASP, performing up to 70% faster than conventional USB 3.0 when paired with a UASP-enabled host
controller. See our UASP testing results below for further details.
This versatile external RAID enclosure features a built-in hardware RAID controller, supporting JBOD, Spanning,
RAID 0, and RAID 1 -- to achieve greater drive capacity, or secure data redundancy.
To maximize both durability and reliability, the enclosure features high-quality aluminum construction with a built-in
fan for better ventilation.
With a stylish white design and silver trim the S3520WU33ER looks great with Apple® computers 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.
