Now let’s check how the use of different controllers affects the performance of a RAID 1 array:

The FAT32 array immediately brings us a surprise. The leader here appears ITE IT8212F controller. Then the second best performance is achieved with VIA VT6410. The third and fourth positions are occupied by Promise controllers: TX2000 and 133Lite.

The tests of a RAID array built under NTFS file system doesn’t bring any changes compared with the pervious case.
