Estimation
The total nonvolatile Flash memory available for archive storage is 7,168
blocks. (A block is 256 bytes.) Table D. 1 shows the memory requirements for
various types of data. Each item requires one to five blocks of overhead, plus
1/7 to 240 blocks per record stored, as indicated in the table.
