From the Manufacturer

The 2.5-inch Seagate Savvio 15K drive provides the world's highest performance and reliability while delivering ultra-low power consumption. By enabling the use of more than twice the drives per the same rack configuration as 3.5-inch 15K drives, the Savvio 15K drive delivers more than twice the system performance. This is especially important in high-performance and blade servers demanding optimized RAID performance per U. The Savvio drive family is part of the new Seagate Unified Storage architecture, which converges hard drive interfaces, form factors and security features into a common best-of-breed platform for powerful, yet simple storage solutions that strengthen business efficiencies.

Seagate Savvio 15K Hard Drives What the experts are saying... High-performance, high reliability and low power enterprise storage in a small form factor drive. Seagate Savvio 15K 2.5-inch hard drives offer both high transactional performance density and low power consumption. These drives are the perfect green solution for high-end and mainstream enterprise server and external storage environments, including: High-performance enterprise servers Database applications Embedded enterprise applications Power- and space-constrained data centers External storage arrays (storage attached networks (SAN), network attached storage (NAS) and direct attached storage (DAS) Drive life extension and drive retirement simplification strategies Why Choose the Seagate Savvio 15K? Increases system-level performance by 115 percent over 3.5-inch 15K-RPM drives Reduces power consumption by up to 70 percent over comparable 3.5-inch 15K-RPM drives with Seagate PowerTrim technology Improves IOPS/W by 2.5 times over comparable 3.5-inch 15K-RPM drives Features a 70 percent smaller footprint than 3.5 inch drives which allows more drives per system for greater performance density and redundancy Supports 6Gb/s SAS for fast data transfer speeds TCG-compliant, Self-Encrypting Drive (SED) security option (SAS models only) eliminates the need to overwrite or physically destroy drives, enables safe return of drives for warranty or expired lease purposes and allows organizations to securely repurpose or sell hard drives (not available in all countries)1
1 Self-Encrypting models require TCG-compliant host or controller support The Savvio's performance was amazing giving me a noticeable performance increase when using it as my OS drive... I would love to see them produce a SATA version of the 15K.2 to compete directly with the VR, until then these business class drives will be our secret ;).
10 out of 10 - Lanoc Gaming Reviews, June 2009 When it comes to the performance of the Seagate Savvio 15K.2, the 146GB drive is capable of churning data at near Cheetah speeds while using less power and having a smaller footprint that allows more drives to occupy less space. - TweakTown, November 2009

The launch of these drives will help Dell PowerEdge server and PowerVault storage customers realize higher density, increased performance and a reduced power envelope compared to similar 3.5-inch solutions... This helps our customers get improved time to data without being penalized with lower capacity or higher electric bills. - Darren Thomas, vice president and general manager for Dell's Storage Business
