The product comes - unlike many external drives - with a case made of imitation leather. The is not of extremely high quality, and closes with a push button, instead of the most common with Velcro, convinced yet: the board can stay inside protected in operating there, the USB port remains free, a broad tether on a corner holds the plate, a small inside pocket is also integrated. The heat generation is low. In addition to the USB port, there is a green LED that blinks during data transfer, otherwise light to indicate for operational readiness. The product comes with a Y-cable, therefore: 2x Computer (for data transfer and power supply), 1x mini-USB to the plate. TrekStor recommends that you connect both USB to the computer, the experience shows that it just does a good plug, also at the hub. Detailed instructions are included as well as in a CD with div. Software for disk partitioning and management (Paragon Partition Manager and all Mouter, full version). A is to get, for example, under Win2k a bootable hard drive FreeDOS disk image. My conclusion: the perfect product to have a mobile data tank, which requires no power supply and is well packaged and protected, even during operation.
