    Industry recognized protection against water and dust, with an IP54 rating

    Keep your data safe and secure even through sudden downpours or dust storms. The robust enclosure provides superior water and dust resistance with an IP54 rating.

    Drop tested for 4 meters (13 feet)

    The rugged drive enclosure is enveloped in a silicone protective sleeve, and engineered to help protect your drive from accidental and unexpected shock, vibrations, and drops. It’s Military MIL-STD-810G rated and test-proven to withstand drops of up to 4 meters (13 feet). It was drop tested using a solid-state drive in the enclosure.

    Data protection inside and out

    Wherever you go, the rugged drive enclosure delivers reliable data protection, inside and out.  The tough-wearing exterior casing provides shock-resistance, while the flexible silicone sleeve hugs the entire perimeter to ensure an extra measure of protection, absorbing the impact of accidental bumps, rough baggage handling or drops. Inside, an extra layer of silicone provides added drive stability.

    Install your drive with ease, with a tool-less design

    It’s easy to turn your 2.5in SATA III (6Gbps) solid-state drive or hard drive into external storage. Simply remove the silicone sleeve, open the latch to insert your 2.5" drive into the rugged enclosure, and plug the included USB cable into the computer or hub USB port. There are no screws or tools needed.

    70% faster than traditional USB 3.0, with UASP

    Save time in the field, by storing and transferring content quickly. Enhanced with UASP (USB Attached SCSI Protocol), this rugged drive enclosure performs with a 70% faster read speed and 40% faster write speed over conventional USB 3.0, when paired with a UASP-enabled host controller.

    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 (6Gbps) solid state drive.

    The S251BRU33 is backed by a StarTech.com 2-year warranty and free lifetime technical support.
