In the server segment systems disk form factor 2.5 are already adapted, their active use is limited to the low capacities range in comparison with traditional HDD standard size 3.5 . Hitachi company with the release of HDD ultrastar C10K600 attempts to break this stereotype.
The HDD ultrastar C10K600 are made in the form factor 2.5 , in this case the volume of proposed models varies from 300 to 600 Gb. The rotation speed is equal to 10 000 rp/min, the buffer volume reaches 64 mb. For the connection to the motherboard is used dual port SAS, which transmits information with 6 Gbit/s speed. In comparison with certain competing product, HDD series ultrastar C10K600 are capable of ensuring 15% higher reading speed of arbitrary data, and 18% higher speed of reading sequential data. The energy consumption level is lower by 22%: under load they consume not more than 5,6 W, in the quiescent conditions - not more than 3,1 W.
Passage from standard size 3.5 to 2.5 allow to decrease by up to 70% the occupied by HDD volume, and by 65% reduce the energy consumption level. HDD can be supplied in the version with the support of data coding system BDE. The deliveries of new HDD already began along OEM- channels.
