—Seagate announced this week that it has begun shipping the next generation of its fastest hard drive—the 2.5-inch, 15,000rpm Savvio 15K—which is based on the Serial Attached SCSI (SAS) interface.
Designed for a range of applications in both large data centers and small to medium-sized businesses (SMBs), the Savvio 15K drive includes a number of improvements over previous-generation drives.
For example, the Savvio 15K is 70% smaller and consumes 30% less power than existing 3.5-inch, 15,000rpm drives. The 2.5-inch Savvio is rated at a mean time between failure (MTBF) of 1.6 million hours.
With data-center space at a premium, the biggest selling point for the Savvio 15K might be its diminutive form factor. "The Savvio 15K offers more performance than previous generations with fewer drives in the same amount of real estate," says Gianna DaGiau, a senior marketing manager at Seagate.
Hewlett-Packard is the first Seagate partner to qualify and ship systems with Savvio 15K drives, which are available in 36GB and 73GB capacities. IBM and Sun are also in the process of integrating the new drives.
With most of the major server vendors shipping systems with SAS drives, end-user adoption of SAS is expected to rev up rapidly. For example, Gartner Dataquest predicts that SAS drives will jump from an 8.4% share of the multi-user disk drive market in 2006 to a 16.4% share this year and a 44.9% share by 2009.
In the enterprise disk drive market segment, International Data Corp. (IDC) predicts the market share for SAS will surge from 7.1% last year to 15.7% this year and 25.9% in 2009. The increased market share for SAS will come primarily at the expense of its predecessor—parallel SCSI, which IDC expects to drop from a 48.8% market share last year to 27.3% this year and only 6% by 2009.
