Hitachi Global Storage Technologies announced the Travelstar Z5K320 today, a new line of 2.5-inch mobile hard drives that are just 7mm thick. The HDDs will be available in capacities of 160GB, 250GB or 320GB. Hitachi says the new HDDs are the slimmest, lightest, and fastest in the industry (at least in this combination).
The top model spins at 7,200 rpm and offers 16MB of cache, but buyers will also be able to get models with 5,400rpm and 8MB of buffer, too.
Hitachi is already shipping samples and expects to kick off mass production in July this year.
