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.”

RE: When, what capacity - what about NOW?

How can you not suggest purchasing new servers? The improvements in CPU thermal envelope alone could justify the replacement. And why not suggest 500GB SATA drives. They are fine for archiving... the only times that you need/want the SAS drives is when you are frequently reading/writing the information and the speed matters. This only seems to be a small percentage of the overall usage.... so why not slap a few high speed SAS drives along side the larger, slower SATA drives for archiving.

I can justify it by not having my clients pay me a big wad of cash for every upgrade available. I want to maximize their bang for the buck. When they have not choice but to upgrade, I will play whatever hand is available. Right now they have a little space left, I'm offloading non critical files to a NAS device - not an ideal solution but better than paying $15,000 for a server with insufficient disk space only to have them pay me again in 6 months when better technology is available. They are already on Windows 2003 latest SP and patches, AD and complimentary Exchange 2k3 servers.

Justification becomes obvious when they can at least double their current storage capacity as demand is increasing at more than double per year. This is the nature of most businesses - IT departments are despised enough due to expenses, limiting their storage capacity without justification is a mine field. I assist in removing and archiving dead files - restrictions can kill a career.

In the past, SCSI drives have increased from 1 GB, 2GB, 9GB, 18GB etc - to the current 300+GB. They are currently stalled along with SAS drives. SATA drives are currently in the 1TB range. I have no doubt SAS drives must grow to at least 500GB soon to meet the demands of MANY clients. I work with many consultants and clients in the field so I know the demands I present are in no way unique. Not all clients require it but I think a signficant portion is represented and as multimedia grows, so will the demand.

BTW, if you know anyone working with the major SAS drive manufacturers, you know the large drives are ready for deployment although the speed is not ideal, it still beats SCSI in a comparable raid configuration. The delay we face is unnecessary in my opinion. I realize they can improve the performance of the large capacity SAS drives, but the demand exists NOW.

Seagate will probably not release 500+GB 2.5" drives for two years; waiting for that would be far less than ideal for my clients.
