Modern stuff is closer to 300K.  But even at 100K, emulating a floppy 
drive gives you about 5.5 hours of continuous rewriting of a single 
track.  CF sector remapping obviously can improve this number.

Heck, I can't get nearly that many writes out of a modern 3.5" 1.44MB 
diskette! :)

Given the proliferation of CF, I can readily envision a not-distant 
future where a technological improvement results in nearly infinite 
numbers of write cycles.  I note that Ramtron is now saying that its 
FRAM enjoys that distinction.
