Hitachi GST, a subdivision on Hitachi Ltd, is being sold to Western Digital in the 3rd quarter of 2011. Hitachi had previously, in 2003, bought IBM’s hard drive division.
Hitachi manufacture 4 product lines of hard drives, the 2 that are common in the consumer range are the Deskstar and Travelstar. Hitachi desktop drives (Deskstar) are not common in South Africa so are not often found in computer systems. The Travelstar, however, ship with numerous brands of laptop manufacturers including Dell, HP and Lenovo. Due to these drives being shipped with laptops there are a number of the Travelstar drives in circulation, although Hitachi are not popular in terms of aftermarket sales.
Hitachi hard drives are generally found to be robust for the most part in terms of electronics and firmware, however the Travelstar series does seem to suffer with read/write head degradation.
