The ultimate in high speed video storage, the MediaVault Max is available in capacities from 600 GB up to 1.25TB - in a single chassis! This system can record and play back digital video at over 100 Megabytes per Second, more than enough for multiple SD video streams. The single channel, high performance Ultra160 SCSI interface is supported by all the popular host adapters. Dual fans and a hefty 250 watt power supply provide cooling and power to spare. (The MediaVault Dual Max is a dual-channel version with capacities up to 2.5TB and MIN sustained data rate of over 200 MB/sec - learn more) The MediaVault Max has 5 disk drives and can be configured for RAID 0 (performance) or RAID 3 (protected) operation. In RAID 0 mode all 5 drives are used for storage and maximum performance (120 MB/sec sustained). When in RAID 3 mode, one drive is used for "parity" information, so performance and capacities are diminished about 20%. In RAID 3 mode if a drive fails your footage will still be there - and you can continue working with no degradation in performance. The MediaVault Max is true Plug-and-Play. Each unit has an on-board programmable RAID controller that takes care of formatting, striping and all RAID functions - while appearing as a single HUGE disk drive to the operating system. The controller also provides built in diagnostics to monitor drive performance and health.
