Seagate company already proposes hard disks for notebook with hardware data coding function , hitachi company promised to release similar hard dicks in the present half-year . Actually, the latter decided to immediately update its hard drive : users will obtain faster , larger(In volume) and data coding protection for their notebook hard disks .
To all these criteria correspond the announced yesterday hard disks series hitachi travelstar 7K200, which use perpendicular recording. The high end model with volume 200 Gb has the rotation speed 7200 rp/min, it is equipped with 16 mb buffer and support SATA-300 interface . As option hitachi proposed the hardware data coding function .
Hitachi asserts that hard disks series travelstar 7K200 require less energy inputs and make less noise than 5400 rp/min hard disks . The function hardware data coding do not hurt the hard disk performance and the volume does not decrease.
Talking about the speed level , hard disks series travelstar 7K200 are up to 22% faster than predecessors and up to 25% faster than competitors in PCMark'05 benchmark .
Hard disks series travelstar 7K200 are presented in models with volume from 80 to 200 Gb. Hard disk with capacity 100 Gb use one magnetic disk, rest use two magnetic disk. Those new disks are capable of maintaining load up to 350G (with 2 ms length ) and up to 1000G (1 ms) in the non-operating state.
Hitachi also provided three models series travelstar E7K200 with capacity from 120 to 200 Gb, which differ in terms of the increased reliability and oriented to the twenty-four hour use. The deliveries of those hard disks will begin during July, recommended price is $249. Now the share of hard disks with 7200 rp/min in mobile segment composes 10%, to 2010 this value can reach 40%.
