Hitachi has a range of solid state drives for enterprise and server applications released. The new Ultrastar-series does not, however, with slc memory, as usual, but with the cheaper mlc memory.

The Ultrastar SSD400M series of Hitachi Global Storage Technologies is available in capacities of 200 and 400GB. Hitachi makes use of Intel’s mlc memory chips, which the company, according to a 25nm process produces. Hitachi GST used chips are not the typical mlc-chips, which Intel in its consumer solid-state drives used, but so-called emlc chips, either enterprise-grade multilevel cell memory.
