Now let’s consider the same RAID 1 array performing in NTFS file system:

The files are created faster when the array works with VIA VT6410 controller. The drives work a bit slower when we have ITE IT8212F. Among two Promise controllers, the TX2000 model is a bit more efficient than 133Lite.

The results of file reading are very close for all four controller solutions. Although VIA VT6410 and ITE IT8212F look a little better, as RAID array performs somewhat faster with them.

You can clearly see from the diagram that the file copy within one partition is performed faster when we have VIA VT6410 and ITE IT8212F controllers involved. Note that the latter is somewhat more efficient. Both Promise controllers are equally fast having demonstrated almost the same copying speed.

We have finally come to the very last diagram for today. The situation during file copy from one partition to another didn’t change the situation that much compared with the previous case. The array is again in the most advantageous situation with ITE IT8212F or VIA VT6410 controller, with ITE IT8212F being a little bit better still. Both Promise controllers do not make such a great impression this time: the copy speed is much lower, and we hardly see any performance difference between two of them.
