SuperTrak SX6000 Pro gives users the power, protection, and RAID performance previously found only in expensive, complex SCSI RAID environments at a far lower price point. This Ultra ATA/100 RAID 5 "Hot Swap" kit bundles 3 SuperSwap units with 1 SuperTrak SX6000 ATA RAID 5 card.SuperTrak SX6000 targets the more-demanding, medium-sized user environments that expect high data throughput, exceptional fault tolerance, and faster RAID calculations for always-ready data access. SuperSwap uses the fastest and latest Ultra ATA/100 drives around to support high transfers and huge storage capacities. The drive bay delivers continuous operation even if a drive fails and must be replaced as part of a fault tolerant RAID 5 or 1 drive array. With a SuperSwap drive bay installed, there's no powering down your system or opening the PC chassis to exchange hard drives. There's simply no better way to get the most from a Promise ATA RAID controller card than the SuperSwap professional "hot swap" removable drive bay.
