Some very exciting news came out of Seagate this week, with the announcement of both perpendicular storage in use and the development 750GB desktop hard drives. The drives in particular are incredible offering 250GB per platter, resulting in the potential for a 1TB 4-platter drive in the future. 750GB is far larger than anything seen per-disk in a desktop platform yet, and this size increase comes not long after 500GB drives made their way into the market, leaving a lot of potential for more growth in the next year.
Seagate has technical specifications and more information about the 750GB Barracudas at their site. It looks more or less run of the mill for a Barracuda on paper, excluding the behemoth size, but coupled with increased data density and perpendicular storage, it may end up also being a performance winner.
