Seagate Cheetah 15K.6 Hard Drive
IOMeter - Multi-Disk RAID Configurations
These drives scale very well when it comes to Iometer. While a single drive maxes out at about 380 IO's/second, two drives scale up to 790 IO's, three drives up to 1100 IO's, and four drives up to a whopping 137O IO's. Even in RAID-5, our numbers look great across the board. The Cheetah drives tend to show their best performance numbers under moderate load.
