"The DAT 72 model on review is the external version which is well built with the drive enclosed in a sturdy plastic chassis. The USB cable is fixed at the rear and the internal power supply means the drive can be powered with standard kettle lead. Our only complaint is that the internal cooling fan is a tad on the noisy side. The drive uses compact 4mm tapes and has the added advantage of being backward read and write compatible with DDS-4 and DDS-3 media as well. Installation is a swift process as the drivers need to be installed first after which the drive can be plugged in. "
