Data Sheet
4.0 CAPACITY SPECIFICATION
Table 4-1 shows the default capacity and specific settings for heads, sectors, and cylinders. Users can change the
default settings in the drive ID table (see Table 11-4) for customization. If the total number of bytes is less than the
default, the remaining space could be used as spares to increase the flash drive endurance. It should also be noted that
if the total flash drive capacity exceeds the total default number of bytes, the flash drive endurance will be reduced.
