Title: Hitachi to release 1 TB hard drive
Description: After scheduling the release of the first 1 TB hard drive in 2006, Hitachi postponed the date to the first half 2007 and they kept their promises. The manufacturer has officially announced the release of the Deskstar 7K1000 at an MRSP of $399 approximately.

In fact this series include also a 750 GB hard drive with four platters (5 are required for the terabyte) of 200 GB instead of 160 to 170 GB for the previous generations. This density is of course reached thanks to perpendicular recording.

The 7K1000 are also available in PATA version with 8 MB of cache but also in SATA with 32 MB of cache! Access time is unchanged to 8.5ms reading and 14ms when noise level management is activated.

Despite the presence of 5 platters, the noise level announced as relatively low 29 dB in stand by, 32 dB during accesses and 30 dB with noise level management. Power consumption reaches 13.6 Watts in use with the 1 TB and it weights 700g.

We remind you that hard drive manufacturers do not base their calculations on the IT definition (1 KB = 1024 octets) used by our OS but on the officialised norm which is much more favourable to them (1 KB = 1000 octets). This is the reason why, the 1 TB hard drive will only be of 931.3 GB or 0,91 TB according to the softwares…
