300GB 2.5" SAS drives from HP

By | December 9, 2008, 3:33pm PST

Summary: HP has begun shipping 300GB 2.5″ 10,000 RPM SAS (Serial-Attached SCSI) hard drives.

HP has begun shipping 300GB 2.5″ 10,000 RPM SAS (Serial-Attached SCSI) hard drives.

Produced in association with Seagate, these new SAS drives use 75% less energy and are 70% smaller than 3.5″ SAS drives. This means that storage arrays can be more efficient, cooler and have higher capacities. Previously the largest 2.5″ SAS drive was 146GB, while 3.5″ SAS drives peak at 450GB.

The only drawback of these drives is that the RPM is limited to 10K, while the sweet-spot for enterprise storage is currently 15,000 RPM. Still, the space and energy saving should appeal to data centers looking to save money or increase capacity without increasing server volume.

Please re-read the article.

The topic was about SCSI drives, not SATA or SAS. SATA exists up to 1.5TB actually with the Barracuda, but SCSI is completely different interface. They are meant to be fast drives for enterprise applications - which is why no mobo comes with an SCSI controller (though it is possible to purchase an expansion card). These drivers are all 10,000 or 15,000 RPM because latency DOES matter in server environments.

seagate proposes its barracuda ES.2 in SATA and SAS from 500Gb to 1000Gb. OK these are only 7200 disks, but some usages does not require low latency.
