USB 3.0/eSATA Dual 3.5" SATA III Hard Drive External RAID Enclosure w/ UASP and Fan
S3520BU33ER

Overview
Create an external dual 3.5in HDD SATA RAID array, connected through either USB 3.0 with UASP or eSATA


Features
UASP Support (Attached SCSI Protocol Specification Revision 1.0) eSATA or USB Host Connection Compatible with SATA revision I/II/III (1.5/3.0/6.0 Gbps) Hardware RAID Plug-and-Play Compatible Dual Drive Bay Built-in Fan

Description
The S3520BU33ER 2-Bay RAID Enclosure offers a high-performance external storage solution, enabling you to build a secure RAID array with two 3.5" SATA hard drives, with the option to connect it to your computer through either an available USB 3.0 or eSATA port.
For fast data transfers and efficient performance from your SATA III drives, the RAID enclosure supports full SATA III transfer speeds (up to 6 Gbps), as well as full USB 3.0 transfer speeds (up to 5Gbps). When connected through USB, the enclosure supports UASP, which offers performance up to 70% faster than conventional USB 3.0 when paired with a UASP-enabled host controller (see our performance below).
With support for JBOD, Spanning, RAID 0, and RAID 1,the enclosure offers several options that enable you to customize your drive arrangement based on your storage requirements.
To maximize both durability and reliability, the external RAID enclosure features high-quality aluminum construction with a built-in fan that helps improve ventilation and maintain a better operating environment for your drives.
The HDD enclosure offers a versatile solution for increasing the storage/backup capabilities of your computer, with support for large capacity hard drives (tested up to 4TB).
To ensure compatibility with your computer system, the S3520BU33ER 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™.
It 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.


The StarTech.com Advantage
Versatile connectivity options, through either USB or eSATA Time-saving file transfers, up to 70% faster than traditional USB 3.0 when used with a UASP-supported host Achieve greater drive capacity or secure data redundancy with multiple RAID modes Maximize performance, with file transfer speeds up to 6Gbps using SATA III

Applications
Business applications that require external RAID storage for data redundancy Video editing or photography professional/enthusiasts working with very large file sizes Transfer large files between computers quickly and securely without a network Scenarios requiring easy storage transferability between different computer systems and large volume external storage for backups/archiving
