Swap is virtual memory, which means it is an extension of your RAM.
Typically, you want this to be the third fastest storage available
(first being CPU cache, second being main RAM). Flash can be even
slower than your hard drive, making this a poor choice for performance
reasons.
The flash memory we are using for our solid-state Linux boxes
stores/retrieves data at 600 Kilobytes/sec, making it 4x faster than a
1x CD-ROM. The newer flash runs 10x faster, making it 1/2-1/4 as fast
as a hard drive.

In business, there are always problems. It's how they are handled
that makes a difference. Are you happy with your IT Manager?
