I can read. I am skeptical.

Flash is notably slow. Since writing, I have done some research. If you 
want good performance (60 Mbytes/sec), it's expensive. You still have a 
limited number of writes.

Don't use consumer-grade flash for this if reliability and performance 
are important. Industrial grade is good. It also costs.

I heard, on another list, of someone who inserted a flash drive and 
exceeded the writes limit on first use. It was fairly big then, 4 
Gbytes, and had a FAT filesystem.
