AREA released a unique portable hard drive enclosure that allows you to switch between SATA and USB 3.0 interfaces (model: SD-S35U3-SL2). Its modular design allows this change. When in SATA mode, the USB adapter is detached, and a cap covers the direct SATA (power+data) interface of the enclosed drive. When in USB 3.0 mode, the adapter interfaces with the SATA power/data connections, supplies power from an external DC power adapter, and connects the drive to a USB 3.0 host. It is backwards-compatible with USB 2.0. Switching between the two modes, and replacing the enclosed drive is a tool-free process. Measuring 190 x 133 x 38.3 mm, and weighing about 780 g (empty weight), the enclosure's body is largely made of brushed metal that's ridged on the sides to dissipate heat. Slated for April 16, the SD-S35U3-SL2 is priced at 2,480 JPY (US $30).
