Du you have used SATA drives with PATA Hardware or WD Raptor WD360GD
and WD740GD which have real SCSI-Hardware. They run with 10.000 RpM.
My @home PostgreSQL Server use the 3w8506S-4LP and is now around 30
times faster as the previous 3w7507-4LP which was PATA.
I am using 4 Western Digital Raptor WD740GD SATA drives.0
I am using Raid-5.
