Abstract:
1. A method of writing data to a disk, said method performing a write-modify-read for every partial 8 byte write, said method comprising: receiving a request for a sequence of L bytes; determining whether the last byte of the sequence of L bytes is the last byte of an 8 byte boundary in a sector of the disk; modifying, if the last byte of the sequence of L bytes is not the last byte of an 8 byte boundary in a sector of the disk, the number of bytes L by an amount of bytes that would allow the last byte of a reduced request to be the last byte of an 8 byte boundary in a sector of the disk, said modified number of bytes represented by M; requesting a sequence of M bytes; receiving the sequence of M bytes; writing the sequence of M bytes to one or more disk sectors with continuous write steps whereby the sequence of M bytes does not need a partial 8 byte write and there is no read-modify-write step.
