Seagate releases 2.5in storage drive

Seagate Technology has launched the Savvio family of small form factor 2.5-inch enterprise disc drives, and announced that Hewlett-Packard is likely to be first to market with products using the drives. 

The higher input/output per second rate of the smaller drives means that a 2U rack storage array using them will outperform a standard 3U rack by almost 140% while giving similar storage capacity, claimed Seagate senior marketing manager Shawn Hook.

HP said in December that it would add enterprise-class 2.5 inch drives to its ProLiant range of servers. It had been testing products from Fujitsu, and Hook said Seagate is also supplying trial versions of the Savvio to HP.

"If I was betting, I'd say HP will be one of the earliest to market with the form factor," Hook said. "They've been one of the innovators in the area."

Target markets for Seagate will include high-performance storage arrays, 1U servers, blade servers and space-constrained environments such as copiers and medical imaging.

The 2.5-inch disc drive uses 40% less power than a 3.5-inch drive, and is available in 36.7Gbyte and 73.4Gbyte capacities. It uses a 10,000 RPM motor and a shortened, stiffer actuator arm to improve I/O performance.

Interfaces will include Ultra320 SCSI and Fibre Channel, with serial attached SCSI (SAS) available later.

A full evaluation specification model, with Ultra320 SCSI and Fibre Channel interfaces, will be available in June, with volume production is expected the same month. Seagate's principal manufacturing customers already have engineering specification versions for trial. A SAS SCSI interface version will be in production by September.
