Yes, the Western Digital S25 SAS enterprise drives have been around for some time, but this generation is special. WD has just shipped the third-generation of the 2.5" SAS HDD family, serving the performance-optimized, mission-critical enterprise server and storage market. Shipping now, the new 2.5-inch, 10,000 RPM, WD S25 with SAS 6 Gb/s interface hard drives offer IT professionals a more advanced array of ultra-reliable and efficient, high-performance storage, available in capacities of 300 GB, 450 GB, 600 GB, and 900 GB. The WD S25 line is designed for the most demanding applications such as online transaction processing and multi-tiered networked storage arrays.

"Continuing our commitment to the industry's fastest-growing segment -- 2.5-inch drives -- WD is updating our small form factor SAS offering with the advanced technology of our third-generation drive, including a new 900 GB capacity point," said Darwin Kauffman, vice president of enterprise storage solutions, WD. "Our latest generation of WD S25 SAS drives offer a powerful combination of enterprise-class performance and industry-leading reliability that is ideal for demanding high-performance computing and mission-critical environments. WD is also delivering higher capacity offerings and the power efficiency of the small form factor footprint, providing the most efficient storage solution for IT professionals and enabling lower TCO (Total Cost of Ownership)."


The new family of WD S25 SAS drives has the speed required to service any enterprise need, delivering high performance with its 6 Gb/s SAS interface. With its small form factor allowing for more system airflow, resulting in lower cooling costs for customers, the latest WD S25 SAS drives require less than 8 watts to operate and have a 2.0 M hour MTBF rating—the industry's highest.  WD's third-generation of 2.5-inch SAS drives are also its first to include support for T10 Protection Information (PI) for advanced data integrity, and the first to provide optional models that feature drive-level self-encryption that meets the Trusted Computing Group's specification for Enterprise Class A encryption.

WD S25 SAS hard drives are currently shipping to OEMs, with broader availability at select resellers and distributors worldwide later next quarter. WD S25 SAS hard drives are covered by a five-year limited warranty.

i always thought WD's SCSI/SAS drives were kind of half-assed. they have never seemed to shoot for anything but the middle of the road with their enterprise SCSI drives, while having top notch enterprise ATA. I know that they have a relatively small share of the SCSI market when compared to seagate, hitachi, and fujitsu.....but it doesn't seem like they have ever made any sort of push for it. I'm a hitachi man when it comes to SCSI/SAS. this is still a pretty big market too, as much as you would be led to believe that SSD's are replacing everything. Can't help but think these are nearline SAS drives that they concocted out of left over raptors. Also, 15k drives are considerably faster than 10k drives,,,,but WD doesnt seem to care.
