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.
