The drive uses proven SCSI drive architecture and industrial CFast or M.2 SSD memory, and has storage capacities ranging from 2GByte to 1TByte). Hardware is configurable in order to replace or upgrade legacy systems from the 1980s onwards. It can automatically detect 16- or 8-bit data operation, as well as single-ended (SE) and low voltage different (LVD) signalling. More than one SCSI address and logical unit number (LUN) can be supported by a single unit, and its microcode is field-upgradable via USB.
