The S352BU33RER 2-Bay RAID enclosure lets you build an external RAID array with two 3.5” SATA hard drives, and connect to your computer through USB 3.0 or eSATA.

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.

The external RAID enclosure features a hardware RAID controller, supporting JBOD, Spanning, RAID 0, and RAID 1 -- to achieve greater drive capacity, or secure data redundancy. The RAID controller is also front mounted for ease of access when changing your RAID mode.

For fast and easy drive installation and removal, the dual drive enclosure features a convenient trayless system that eliminates having to mount and fasten your drives, saving time and hassle.

To ensure compatibility with your computer system, the S352BU33RER 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 S352BU33RER is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Works good with some tweaking.

I had it for 4 months. I wanted a Raid0 for my games. Tried the 3.0. USB cable and it initialized great but I lost my raid after a couple of days. Also, I had to connect and disconnect everytime my laptop when to sleep or idle for too long. I tried disabling all USB sleep times and nothing. I kept losing my Raid0 after a while. Then I got a brainstorm and decided to use the eSATA to USB that I bought with it which I did not think I need it. I connected the eSATA side to the enclosure and the USB directly to the laptop bypassing all HUBS. WORKED GREAT. It has been three months now and my Raid0 is intact half way full with games and works super fast and my games have no lag whatsoever. the only thing I dont like is this humming sound it makes when it turning on or off. It makes me feel like is about to fail. Is not my drives is the enclosure making that weird, old sound humming. Other that that, it has been working great with the eSATA to USB cable.
