High Performance: High rotational speed (5,400rpm) and large-sized cache (8MB*1) have contributed to the read and write operation in high speed. Large capacity: Massive capacity has been achieved through the use of a GDT (Glass Direct Texture) Media *2allowing up to 10.7Gb/cm2 (69Gb/in2) high density and up to 40GB*3 per disk, 80GB*3 per drive (2 disks) high capacity. Shock Tolerance: FDB (Fluid Dynamic Bearing) spindle motor *4 and Head Load/Unload mechanism *5 enable in high shock tolerance.
