This USB 3.0 2-bay enclosure for 2.5in drives gives you the performance you want in an external storage system - and features a stylish, compact design that looks great next to your Mac or PC.  Ideal for professional business settings or home offices, it provides a powerful data storage solution for your desktop computer, laptop, Ultrabook™ or Chromebook™.

High capacity, high performance external storage

The dual drive enclosure lets you install two 2.5in SSDs or HDDs (from 5mm to 15mm) to create high capacity external data storage. To maximize the performance and speed of your SATA III (6Gbps) drives, the enclosure is enhanced with UASP delivering up to 70% faster transfer speeds than conventional USB 3.0. (See testing results below.) 

Sleek, compact design with flexible power options

With its compact design and small footprint, this high performance 2-bay enclosure occupies minimal space in your work area

The compact design, small footprint and sleek finish make this enclosure the perfect desktop companion for your Mac or PC.

Requiring only 5V of power, you have the option to power the enclosure through USB alone, without the need for an external power adapter. It can be powered through a single or two USB sources, such as USB chargers or ports on your laptop, depending on your drive set-up. In stationary applications or configurations where more power is desired, a power adapter is included.  The enclosure gives you a convenient, energy-efficient storage solution with flexible storage set-up options - and easy portability.

Increased performance and data redundancy with RAID

Enjoy peace of mind, knowing your files are continually backed up or take advantage of greater speed and capacity offered with a combined solution. The enclosure supports RAID 0, 1, Spanning, and JBOD, enabling you to choose your preferred backup mode. With the convenience of RAID, you can achieve increased size, performance, or redundancy.

The enclosure is compatible with Windows®, Mac®, Chrome OS™ and Linux® systems without having to install additional drivers or software.

Enhanced performance through UASP

This high-performance SuperSpeed USB 3.0 enclosure supports data transfer rates of up to 5Gbps and is enhanced with UASP support, which can deliver ~70% faster read speed and 40% faster write speed over traditional USB 3.0, when paired with a UASP-enabled host.

UASP speed benefit diagram

The S252BU33R dual-bay enclosure is ruggedly built to deliver long-lasting performance, and is backed by a StarTech.com 2-year warranty and free lifetime technical support.

A really nice compact and very reserved design. This is the only drive enclosure I could find that fit 2.5" HDDs and SSDs, with SATA 3 and USB3. Very please with this, coupled with two WD red dives it very fast and runs very cool. The only improvement I would make would be to add a quick release/open latch rather than screw entry.
