The Dedicated Micros RAIDR82T4 is a 2.4TB RAID array for use with DM's digital video recorders. A redundant RAID array not only provides additional storage space but also offers fail-safe operation by being able to recover information from a failed disk. This makes it ideal for use in high security applications. This unit is compatible with all DM DVRs having a SCSI-2 connection including the ECO4 series.
