MILPER‘s MRMEU-109, series of Rugged Memory Expansion Units, are designed for high speed, mass data storage and retrieval applications. Each system consist one or two removable disk cartridges. The MRMEU-109 Disk system features an environmentally - sealed and pressurized Disk cartridge and a Magneto Optical Disk Drive, (second hard disk drive in place of the MO drive is optionally available for achieving larger capacity).

Ruggedized for operation in severe environments - where extreme temperatures, shock, vibration, humidity and air pressure are common - the MEU-109 is field proven in ‘‘on-the-move‘‘ operation in tracked and wheeled vehicles, as well as airborne application.

Since no warm up time is required, near instant readiness is provided at all operating temperatures. The sealed, cast aluminum housing encompasses the entire drive mechanism, including electronics, isolating the drives from shock and vibration and protecting itfrom high humidity and changes in altitude.
