Hello again,

Here is an article on USB Flash drives on Wikipedia.

<http://en.wikipedia.org/wiki/USB_flash_drive#File_system>

They claim a million write operations for "some of them", which I 
suppose could be easily done in 8 months on an actively used system like 
mine.

My attraction is the price of $12.99 for a 2 gig drive at Crucial.com 
compared to around $83 for 2 gig of RAM. On my low budget that's an 
enticement, however it may be false economy considering the low life span.

Later, Ray Parrish
