| 42 * | |
| 43 * The standard for iostreams is to call flush. This is very costly for | |
| 44 * SdFat. Each call to flush causes 2048 bytes of I/O to the SD. | |
| 45 * | |
| 46 * SdFat has a single 512 byte buffer for SD I/O so it must write the current | |
| 47 * data block to the SD, read the directory block from the SD, update the | |
| 48 * directory entry, write the directory block to the SD and read the data | |
| 49 * block back into the buffer. | |
| 50 * | |
| 51 * The SD flash memory controller is not designed for this many rewrites | |
| 52 * so performance may be reduced by more than a factor of 100. | |
| 53 * | |
| 54 * If ENDL_CALLS_FLUSH is zero, you must call flush and/or close to force | |
| 55 * all data to be written to the SD. | |
