When doing database stuff, you're most likely to run into the number
of I/Os per second limit long before the bandwidth limit.
On my queries, an IDE drive perfectly cable of transferring 30
MB/sec. ends up transferring more like two or three, because it
can't do more than about 140 reads per second, and the reads are
only 16K.
