Unlike the iPhone fanfare that has dominated the news and websphere for the past few days, this announcement by Seagate all but disappeared in the hype. But this announcement of a 50% larger capacity storage is indeed a monumental step up in storage. The largest 3.5" hard disk drive (HDD) available today is one terabyte offered by Hitachi (and others). It has been about a year and a half since the 1Tb 3.5" drives hit the market with no manufacturer offering a larger capacity drive since, so this bump in capacity is way overdue and definitely welcome. While there are external drives that have capacities larger than one terabyte, the larger capacity is achieved thru RAID striping of multiple drives. On Thursday Seagate announced the Barracuda 7200.11 HDD, the worlds first four platter perpendicular magnetic recording (PMR) technology 7200RPM 1.5 terabyte drive which is expected to begin shipping in August. In addition, Seagate also annouced new 2.5" laptop drives in its Momentus® line of HDD's-the Momentus 5400.6 and Momentus 7200.4. The largest, a 500Gb 7200rpm drive that has a 16Mb cache. The 2.5" drives are expected to ship in Q4 2008.
