Overview

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.

UASP Speed Diagram

At the same peak in testing UASP also shows an 80% reduction in required processor resources.

UASP Speed Diagram

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

  • Save time, with file transfers up to 70% faster than traditional USB 3.0 when used with a UASP-supported host
  • Charge your iPad and other mobile device faster than standard USB 3.0, with fast charge port
  • Preserve system resources using hardware-based RAID instead of software

Applications

Build an external RAID 1 array for data redundancy, to protect against drive failure when working with important data

Externally work with very large files securely in video editing or photography applications

Quickly transfer large data files from your computer to a secure external RAID enclosure

(1 star) Sorry Guys, the Drive Keeps Crashing

By:
I have had this drivebay for a little over a month. Every week I have had to reformat the drives because the OS says that the drives are no longer readable. I have it set for RAID 1. Luckily I am using it as a utility drive, so the data is not too important, but losing the drive upon reboot is a real problem.
