| 14 | help | |
| 15 | Many flash memories support erasing small (4096 B) sectors. Depending | |
| 16 | on the usage this feature may provide performance gain in comparison | |
| 17 | to erasing whole blocks (32/64 KiB). | |
| 18 | Changing a small part of the flash's contents is usually faster with | |
| 19 | small sectors. On the other hand erasing should be faster when using | |
| 20 | 64 KiB block instead of 16 × 4 KiB sectors. | |
| 21 | ||
| 22 | Please note that some tools/drivers/filesystems may not work with | |
| 23 | 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum). | |
