Seagate Technology, the world’s largest producer of hard disk drives (HDDs), on Monday unveiled several new hard drives that feature the world’s highest capacity to date as well as several improvements over previously introduced models. The new 1TB HDDs feature larger caches and Serial Attached SCSI interface for enterprise-class systems.

The new leading-edge hard drives from Seagate are Barracuda 7200.11, which is aimed at desktops as well as consumer applications, and Barracuda ES.2, which is designed for enterprises. Both new hard drives feature capacities up to 1TB, 7200rpm motors, 250GB platters, but are equipped with large up to 32MB caches, which is two times higher compared to Barracuda 7200.10 with 1TB capacity.

The Barracuda ES.2 sports Serial Attached SCSI (SAS) interface along with new PowerTrim technology that dynamically manages drive power consumption at all levels of activity. With PowerTrim, the Barracuda ES.2 addresses the IT dilemma facing energy-constrained data centers by delivering a 20% reduction in overall drive power consumption and a best-in-class 55% reduction in watts-per-gigabyte, according to Seagate.

The Barracuda ES.2 and 7200.11 will begin shipping in volume during the third quarter. The 1TB Barracuda 7200.11 will be offered at manufacturer’s suggested retail price (MSRP) of $399.99, which is similar to the price of Seagate’s current 1TB HDD.

“The need for high-capacity storage in enterprise networks and home entertainment centers is almost insatiable,” said John Monroe, a research vice president at Gartner. “Historians may consider the shipment of 1TB drives as a watershed event for the industry but users will consider such devices commonplace. We believe 1TB (and larger) drives will become ‘standard equipment’ in, on or near virtually every television set in the world as well as in a variety of multi-user environments.”
