    As storage capacity requirements increase, using data storage without drive fault tolerance implemented increases the potential of lost data, down time and lost revenue. Our RM4-eS is a highly reliable protected hardware RAID 0/1/3/5/10 level, if a HDD fails and a new HDD is inserted, or a hot spare is available, the built-in RAID engine will reconstruct the BAD drive, while in service, so the data stays intact.

    DAT Optic introduces a hardware 4 drives RAID, offering a cost-effective, highly reliable and fast data transfer rate RAID/JBOD solution. In a quiet over-kill 300W power supply tower coupling four SATAI, II, III tray-less bays featuring DirectAirtm technology with the eSATA host. RM4-eS is a must-have solution for application that needs FAST, HIGH RELIABILITY, SILENT and easy to manage storage.

    Support TrueCrypt
    For sensitive data, now end users can encrypt entire files volume with our RM4eS+TrueCrypt. Our RM4-eS has been tested with TrueCrypt in Linux, MAC and Windows. RM4-eS transfers over 200MB/sec with encrypted files, thanks to embedded I/O processor in our controller to minimize usage of host CPU.
