Tekram-U3-205

5 Bay IDE RAID Subsystem

Tekram combo-205 combines high speed FireWire800/1394b, FireWire400/1394a, and USB 2.0 host connections with ATA/133 drive interface, to offer blistering performance, easy to manage redundancy and secure IDE RAID subsystem. The IDE RAID subsystem offers easy scalability from RAID levels 0, 1 (0+1), 3, and 5 to just simple JBOD, RAID configuration and monitoring can be done through the local LCD front control panel or serial port, and offers true plug’n’play to any Windows or Macintosh environment with no software and drivers required, making it very easy to use with minimal technical maintenance.
