|
||
Many flash memories support erasing small (4096 B) sectors. Depending
|
||
on the usage this feature may provide performance gain in comparison
|
||
to erasing whole blocks (32/64 KiB).
|
||
Changing a small part of the flash's contents is usually faster with
|
||
small sectors. On the other hand erasing should be faster when using
|
||
64 KiB block instead of 16 × 4 KiB sectors.
|
||
|
||
Please note that some tools/drivers/filesystems may not work with
|
||
4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
