Key Features • 3TB capacity with 64MB cache Enterprise/RAID Edition hard drives • 7200 RPM Serial ATA drive Hard Drive Expansion Whether you have your Fusion RAID storage system configured with a hot spare, perform incremental backups, or swap out large amounts of data, it's always handy to have extra drive modules around. Fusion drive modules employ drives that have been selected for their superior performance, error handling, and reliability characteristics, especially when used in RAID groups. These drives are subjected to hours of additional, stringent testing to check for soft errors, vibration, and other reliability predictors. Just the sturdiest drives pass these tests and are prepared with special RAID-optimized firmware to become the building blocks of a super-reliable Fusion storage system. Compatibility • Compatible with Fusion DX800RAID, DX800RAID Expansion, RX1600 Expansion, RX1600RAID, RX1600Fibre, and RX1600 Vfibre (with platinum drive modules)
