Seagate, makers of very reliable hard drives, recently upped the ante with the introduction of new 15,000RPM 2.5-inch hard drives. I got all excited when I first heard about this, but have learned that they are not standard SATA hard drives (my MacBook was temporarily smiling), but use a Serial Attached SCSI (SAS) connection.

From Seagate's press release, "Seagate Technology (NYSE:STX) today introduced the world's fastest hard drive - the Savvio 15K drive, the new 15K-rpm addition to the Savvio family of 2.5-inch Serial Attached SCSI (SAS) enterprise drive solutions. The Savvio 15K drive provides the highest hard drive performance density and reliability while ensuring ultra-low power consumption, reducing thermal loads in data centers. With its combination of benefits that were created for modern storage systems, the Savvio 15K drive is well-suited for a broad range of mainstream enterprise applications in both large enterprise data centers and small, medium businesses, that lowers overall system Total Cost of Ownership (TCO)."
