Seagate Cheetah 15K.4B 147 GB (ST3146854SS)
Cheetah has been a synonym for high-performance hard drives for a long time. The enterprise product nomenclature actually worked well enough for Seagate to port its Barracuda name into the desktop space, which resulted in the first 7,200 RPM desktop hard drive in 2000.
There are 36.7 GB, 73.4 GB and 146.8 GB model versions available. All of these run at 15,000 RPM and have 8 MB cache. They feature 3.5 ms read and 4.0 ms write seek time.
