Disk access can be a big bottle neck. Here at work, we have an online course delivery system (WebCT) and we make nightly course backups. They are essentially 3 zip files inside one more zip file. Using 10krpm scsi drives, our backups of 800 odd courses would take just under 12 hours. Changed our storage to fiber attached SAN (bi-directional 2gb/sec data transfer to "disk") and our backups - same courses, etc - now take just 4 hours.
