 My understanding is that btrfs has some smarts to avoid triggering
 excessive wear-levelling when it detects it's running from a
 flash-backed device (a block device which is likely a SSD, SD/MMC, or
 CF etc.).  It might be a better choice than extN to avoid
 wear-levelling.

 I don't use btrfs myself though, but mostly extN.  :-)
