I'm searching for what brand/model/capacity of Flash Memory works the 
best under FreeBSD (formatted in it's default state fat32 usually)

If people could measure the performance of their flash memory and post 
them here that would be cool.  Corsair Voyager and Transend Jetdrives 
are suppose to be fast, if anyone has one of these please post the results.

I'm using bonnie++ 1.93c

Here are my results:
FreeBSD 6.2
Brand:         PQI Corp.
Model:        Mr Flash
Capacity:    512MB
Price:          ~$15AU
