Testing removable media

[Jeff Lane]

Hey folks,

I wanted to ask a quick and dirty question:

What would you consider a "Stress" test of removable media like USB Keys 
& SD/SDHC cards?

I'm working on enhancing a script and so far, the only idea put forth 
was to do multiple simultaneous read/writes (like 100 at a time). But is 
that a realistic stress test for something meant to be small, light but 
with a very slow transfer speed?

Or would it be more appropriate to do something more realistic like, 
transfer increasingly large files up to a pre-determined size (perhaps a 
2GB file size max?)

Cheers,

Jeff
