Sas From the Manufacturer The Seagate Cheetah 15K drive delivers the highest
capacity (up to 600 GB) of any mission-critical drive, reduces storage costs
per GB and increases capacity per watt. Featuring PowerTrimÄ technology, it
dynamically optimizes drive power consumption. With the highest reliability
rating, it's available with a 6-Gb/s SAS or 4-Gb/s FC interface. The highest-
performing 3.5-inch drive, it reduces RAID rebuild times while minimizing
reliability risks. Ideally suited for use in network storage applications, the
Cheetah 15K drive is SAS 2.0-compliant and offers a Self-Encrypting Drive
(SED) option providing government-grade security and instant secure erase for
drives repurposed or returned for expired lease, repair or warranty.
Requires TCG-compliant host or controller support Seagate Cheetah 15K Hard
Drives What the experts are saying... Best performance, highest capacity
drives with field-proven reliability for mission-critical 3.5-inch Tier 1
enterprise environments. Seagate Cheetah 15K drives offer the high

Seagate Cheetah 15K.7 is a remarkable product, no matter if you see it as an
enterprise tool or through the eyes of an enthusiast...À - TweakTown, November
2009 ÀœIn conclusion, the Seagate Cheetah 15K.7 SAS drive has demonstrated a
dominance over existing Enterprise storage solutions and improved file
transfer speeds at the same time as it saves electrical energy costs.À -
Benchmark Reviews, October 2009 ÀœSo after taking a look at the Seagate Cheetah
NS.2 and Cheetah 15K.7 I can say one thing without a doubt, these are two of
the fastest hard drives we have seen. In fact the 15K.7 is just short of SSD
performance with the reliability that only 53 years of development can give
you.À - Lanoc Reviews, October 2009     ÀœFor users looking for the most
advanced technology to create new premium systems, or those who are looking to
extend the life of their existing systems, the Cheetah 15K.7 delivers the low
TCO and promise of easy integration for businesses of all sizes...À - Joe
