Generally, a multiple sector transfer request must not be split into single sector transactions to the storage device, or you will never get good write throughput.
-FatFs expects delayed write feature of the disk functions. The write operation to the media need not to be completed due to write operation is in progress or only stored it into the cache buffer when return from this function. But data on the buff is invalid after return from this function. The write completion request is done by CTRL_SYNC command of disk_ioctl() function. Therefore, if delayed write feature is implemented, the write throughput may be improved.
-Application program MUST NOT call this function, or FAT structure on the volume can be collapsed.
+FatFs expects delayed write function of the disk control layer. The write operation to the media does not need to be completed when return from this function by what write operation is in progress or data is only stored into the write-back cache. But write data on the buff is invalid after return from this function. The write completion request is done by CTRL_SYNC command of disk_ioctl function. Therefore, if a delayed write function is implemented, the write throughput will be improved.
+Remarks: Application program MUST NOT call this function, or FAT structure on the volume can be collapsed.
