The next diagram shows how efficient the tested controllers are when we perform Create operations in an NTFS formatted disk space. Here Intel ICH6R is the winner. It managed to cope best of all with a big amount of smaller files. Three other controllers are almost equally efficient, so that it is really hard for us to single out a winner among them.
File reading is best of all performed by the VIA VT8237: it appeared to be the fastest in all patterns. The second efficient is Intel ICH5R closely followed by its ICH6R relative. The last one is SiS964, though it is not falling too far behind the three leaders.
When we copy large files within the same partition, VIA VT8237 and SiS964 controllers show their best, however in Windows and programs patterns the situation turns to just the opposite. When we have to work with a lot of smaller files, the best solutions appears Intel ICH6R.
Copying files from one section to another names VIA VT8237 the winner in ISO, MP3 and Install patterns. In this case the VIA controller proves even faster than SiS964. In the remaining two patterns Intel ICH6R is better, as it manages to copy many smaller files much faster.
