Now let’s see how the file copy speed depends on the TCQ mode.

There seems to be less of red in the table of efficiency than before. It’s strange since the controller has behaved badly in mixed modes in the earlier tests.

Here are the diagrams for each file pattern:

The RAID1 and RAID10 clearly profit from TCQ. The gain amounted to the whopping 56% for the RAID1 as it was processing large files!
