Western Digital Targeting Enterprise Servers with SAS Hard Drives

Western Digital, the world’s second largest hard driver manufacturer and a favorite of the masses, has decided to play with the big boys, announcing their first hard drive for the enterprise storage market.

The enterprise market is made up of big business, which places heavy, mission critical demands on their hard drives. You need some serious hard drive storage if you plan to offer email, web applications, or cloud-computing services. Drives that can handle the stress long-term, with little chance of failure are favored in this market, currently dominated by Seagate and Hitachi Global Storage Technologies.

Western Digital’s first offering is the WD S25, available in 147 Gb and 300 Gb capacities. The drive, which has a 2.5-inch form factor, spins at 10,000 RPMs. It also includes the technologically necessary Serial Attached SCSI (SAS) interface, either SAS 3 Gb/s or SAS 6 Gb/s. While similar in appearance to Western Digital’s VelociRaptor, it has faster read and write seek times, and a higher MTBF rating of 1.6 million hours.

avatarWhy are SAS drives smaller

Submitted by gendoikari1 on Tue, 11/03/2009 - 7:10pm

Why are SAS drives smaller than the SATA drives of equivalent standing (Newegg has the WD Caviar Black 2TB at $300 while some Hitachi 450GB SAS drive at $400)? Is it that the SAS drive is at 15000 RPM while the WD drive is at 7200 RPM? On a related note, why are there 15000 RPM SAS drives but not 15000 RPM SATA drives?

Well WD SAS 3 Gb/s or SAS 6 Gb/s whatever it is, surely good choice for servers & i saw these drives at micropartsusa.com with a very attractive price.

I might be doing this wrong, but 1,600,000 / 24 / 365 = 182.6 years? Sweet jesus!

That's right (your math).  I wish more hard drives were like this.  I had one die on me the other day after about 3 years of use :(
