SCSI drives have very good performance. When I bought two 160 GB 7200 RPM IDE drives for my home PC I had planned to retire my old SCSI drives but decided to keep my 10,000 RPM 9 GB drive for page file and temp files when I found that the random access re
ad rate (reading 64 KB data blocks) is 20% faster than the IDE drives.
The fastest drives available are 15,000 RPM SCSI drives in RAID 1, but higher density IDE drives have excellent sequential read rates (good for reading very large files). You can get good performance without RAID if you use separate drives for OS, data, p
age file, and depending on the application, temp files.
