Fujitsu’s new 10,000rpm MAP3xxx series includes models with optimum capacities of 36.7GB, 73.5GB and 147GB. The series is thus ideal for all mainstream SCSI applications, such as enterprise servers, PC servers, workstations, and RAID subsystems, where data integrity and reliability are essential.
These new drives offer new performance standards with a maximum internal transfer rate of 107.8MB/s and a fast average seek time of 4.5ms. The series are equipped with an 8MB, multi-segmented data buffer combined with a 32-bit-wide internal data path for faster data access. In addition, the series support Ultra320 SCSI (320MB/s) interface, which boasts new performance and reliability enhancing features, such as data packet protocol, quick arbitration and selection, and signal pre-compensation. The new series also support 2Gb FC-AL2 interface.
Concerning reliability, the new series features the industry’s highest MTBF rating 1,200,000 hours. It also incorporates many reliability enhanced features, such as alloy top cover for lower acoustics and an improved SMART detection system.
