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 10-4) for customization. It should be noted that the total Flash Drive
capacity should not exceed the total number of bytes listed in Table 4-1.
4.1 Functional Specifications
Table 4-2 shows the performance and the maximum capacity supported by each controller.
