All of my databases store telecom data, such as call detail records. The access is very fast when looking for a small subset of the data. For servers, I am using white box intel XEON and P4 systems with SATA disks, 4G of memory. SCSI is out of our price range, but if I had unlimited $ I would go with SCSI /SCSI raid instead.
