Well, the CompactFlash card I use does internal wear-leveling, so all that should count I think are the write cycles. So in that case ext2/3 would not be to big of a disadvantage, would it? But the 2-or-3 question arises since I like the stability of ext3, but don't really know the cost in respect to wearing out the card because of additional write cycles.
Thanks a lot!
