5/6     Just curious what's the upper bound on the number of flash drive
        read/write before the sector fails? Is it 10^10? 10^20? ??
        What about floppies, and HD? Just curious.
        \_ For flash drives it's around 10^4-10^5 IIRC.
        \_ What about Secure Digital (SD) cards?
           \_ Same technology as flash drives.  'Secure' refers to DRM support.
