Next goes the multi-threaded writing test.

The mirroring arrays have performed not quite successfully at writing. They are almost everywhere slower than the single drive and the 2-disk RAID0. This load also almost killed the RAID5 arrays – the 4-disk RAID5 did well when processing one thread, but that was the only gleam of intelligence.

The RAID0 arrays of two and four disks processed one and two threads quite well, but the 3-disk array managed to fall behind the others. With three and four threads we again see the speed of the 2- and 4-disk RAID0 arrays scale up depending on the number of disks per array while the same 3-disk RAID0 again slows down inexplicably.

If you are interested, here are the results of the controller in WriteThrough mode:
