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.

Theexternal RAID enclosurefeatures 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 ofaccess 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, theS352BU33RER 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™.

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.

Rated 5 out of 5 byLocotin from 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.

Rated 5 out of 5 bydoomi from rigid case but has areas for improvementafter around a year or two of constant work as a server raid datastorage the fan stopped working. Replacing it is possible but plug is a bit hard to reach.The documentation, especially for the LED signals should be dramatically improved - some forums are better information sources than the official manual. Something I am currently struggling with and I can't find any info about, is if this enclosure is compatible with 4Kn drives - I have put two 6TB 4Kn (HGST) drives in now and did some tries but do not have the feeling it works (attached via eSATA or USB to a Ryzen 7 system on win10). One LED is constant blue, one LED is constant purple (=red) for over half an hour now and the PC doesn't detect anything. At some point the discs also slow down. Same situation with only 1 drive plugged in. The HDDs themselves are new and both ok and detected fine when directly attached to the internal SATA ports of the PC. The controller is a JMicron - JMS562 which (bad) documentation is also not mentioning 4Kn support, only Win8 compatibility is assured which would speak pro 4Kn, but I fear this is not the case.The enclosure itself is rigid and easy to use. the eSATA cable could be fixed a bit better, but it's ok. the probably missing 4Kn support and the bad LED documentation as well as the broken fan however make me rate it with 2-3 stars max. Oh, and I also lost the raid 1 one or two times with the old disks and was glad I had some backups...
