Seagate's Savvio 10K.2 hard drive
Seagate goes green with low power consumption 10,000RPM SAS drives

Seagate Technology today announced its Savvio 2.5-inch 10,000RPM enterprise hard drives.  The company announced its first 2.5" enterprise drives late last year with the Savvio 10K.1 series, which were also some of the first drives on the market with perpendicular recording capabilities. 

 

Savvio drives consume less power than equivalent 3.5-inch drives -- 5.7W for 143GB, 5.4 for 73GB at idle -- thus reducing system temperatures while the smaller size enables more airflow to cool processors. Seagate boasts its “greenness” in the enterprise by working to address power and cooling challenges that data centers encounter.

 

Smaller platters ensure faster seek times (3.8/4.4ms), while the compact chassis enables more drives per system to maximize IOPS/U performance. Savvio drives also make room for additional memory modules and processors.   The new drives are available with SAS, SCSI and fiber channel interfaces.

 

Seagate claims that its Savvio 10K.2 drives have an average failure rate of only 0.55%, even when running 24/7, making it the most reliable disk drive in Seagate’s roster. In addition, non-recoverable error per bits read rate has been improved to one sector per 10^16.

 

Seagate is quick to point out that its Savvio drives differ greatly from other 2.5-inch notebook drives. The Savvio line was designed from the ground up as an enterprise class drive, sharing more in common with the Cheetah than the Momentus.

 

Enterprise storage customers are juggling demands for space and power in addition to improved performance and cooling efficiencies in data centers,” according to John Rydning, IDC’s research manager for hard disk drives. “A growing number of customers are beginning to realize the benefits of a smaller 2.5-inch form factor enterprise hard disc drive as a solution to these datacenter challenges.”

2.5" SAS drives use the same platter size as 15K rpm 3.5" drives. Spinning the platters in the 2.5" form factor at 15K rpm causes mechanical difficulties that manufacturers are working on right now. But it's not that big of a deal as the I/Os per second of these new drives is 2 - 3 times greater than their 3.5" counterparts (50,000 - 70,000 as opposed to 20,000).

I/O operations are just one benchmark. Latency is another indicator of performance and you can't really get better latency without raising rotational speeds.

Btw. Thanks for the info. I didn't know they used 2.5" platters in 15 000rpm drives. Now I know.
