Seagate Cheetah 15K.3 18.4 GB SCSI Ultra320 Hard Drive

The Cheetah 15K.3 has the lowest cost for 15K drive, and the lowest cost-per-I/O disk drive ever. It is fast, cool, and quiet, and has the highest reliability rating in the industry. 15K RPM spindle speed delivers over 30% more I/Os per second than 10K, and faster sustained transfer rates, enabling the same high performance to be attained, with fewer drives. The drive features 3D Defense System, the most comprehensive drive protection system in the industry, consisting of Drive Defense, Data Defense and Diagnostic Defense. Seagate's Advanced Multidrive System optimizes the drive for maximum I/O performance in Multidrive environments. The Just-In-Time (JIT) feature minimizes actuator impact on power, vibration and acoustics.
