usb flash drive as swap in linux

[George Toft]

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.
