Data storage provider Winchester Systems, Inc. has introduced 400 GB hard drives for its line of Serial ATA (SATA) disk arrays.
The company has incorporated WD Caviar RE2 drives into its FlashDisk SATA disk arrays with 12, 16 or 24 drives to provide capacities of 4.8 TB, 6.4 TB or 9.6 TB in a single enclosure. The expandable SATA arrays incorporate a 16-drive base unit and up to three 16-drive expansion units for a total capacity of 25.6 TB. For the largest applications, a 1U RAID head with dual controllers supports a cabinet with up to 224 drives with a maximum capacity of nearly 90 TB.
The high capacity WD Caviar RE2 SATA drives are reliability rated at 1.2 million hours MTBF (mean time between failure) in high duty cycle environments. WD Caviar RE2 hard drives also employ RAFF (Rotary Accelerometer Feed Forward) technology, which maintains drive performance in servers and storage arrays where rotational vibration robs performance, the company said.
