MHT2040AT - 40 GB, 6.35 cm (2.5 ") ATA/IDE HDD, 4200 rpm, 100 MB/s, 5 V/2 W, 99 g
- Large capacity: Massive capacity has been achieved through the use of a GDT (Glass Direct Texture) Media *1 allowing up to 10.7Gb/cm2 (69.3Gb/in 2) high density and up to 40GB*2 per disk, 80GB*2 per drive (2 disks) high capacity.
- Improvement for Shock Tolerance: FDB (Fluid Dynamic Bearing) spindle motor *3 and Head Load/Unload mechanism *4 enable in high shock tolerance. The drives withstand up to 900Go-p (duration 1ms) non-operating shock and up to 225Go-p (duration 2ms) operating shock.
- Improvement for Silence: FDB spindle motor and the improvement of seek control *5 are incorporated for silent operation.
- Reduction of Power Consumption: Power consumption under the read/write operation is reduced about 10% by New LSI technology.
- High Performance: Read Ahead Cache *6 and Write Reordering Cache *7 enable the drives to execute read and write operation in high speed.
- High Reliability: 320bit length ECC (Error Correction Code) and S.M.A.R.T *8 function enable the drives to improve the data reliability.
