RAID 6 I/O Performance
The difference between 4 kB and 128 kB stripe size is noticeable even if there is no pending command queue (Q1). Larger stripe sizes do in fact enable more I/O operations per second, while an increasing command queue depth also increases I/O performance. While small stripe sizes of 4 kB and 8 kB only double or triple the I/O performance at large command queue depths (16 commands and up), larger stripe sizes multiply the number of I/Os per second.
