The bottom line is that the SCSI/IDE distinctions is more of an indicator of the drive, rather than the main feature of the drive. The main feature is that certain drives are Enterprise Storage and are designed for high reliability and speed, while Personal Server drives are designed for low cost. The IDE/SCSI issue is only an indicator of this. There are a lot more variabilities between these two types of drives than I knew. I recommend it for anyone who is choosing drives for a system. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073
