The disk drive is the "Slowest" component in any PC. Even with SATA
3.0 Gigabyte drives you'll be hard pressed to get a sustained throughput
of beyond 90 Megabytes. The buffering effects aren't nearly as severe
if you use a SATA DVD-RW. Even with that most - SATA optical drives
run in a UDMA Mode 2. Hopefully we'll start to get some relief when
the newer Hybrid disk drives become more commonplace. The other
issue is the single/"LARGE" drives in use today. It's better to use more
physical drives to distribute the workload. I guess you could improve
things with RAID but for home users that introduces other problems.
