The linear reading graph for RAID 1 is very similar to the previous one. Again VIA VT8237 dashes forward during smaller data blocks processing. Intel’s solutions are again on the second and third place being farther ahead SiS964 due to their better performance with smaller data blocks.
Now let’s take a look at writing:
In case of RAID 0 the laurels are won by Intel controllers: this victory is achieved due to fast linear write speed during 2KB-32KB data blocks processing. In all other situations the results of the controllers are almost identical. The remaining two solutions are also almost equally efficient here, with VIA VT8237 being just a tiny bit ahead.
Another graph shows the linear write speed for RAID 1 array. I would say that here Intel controllers can hardly boast an advantage, because they are just a little bit faster when working with small data blocks than VIA VT8237 and SiS964. Among the other two controllers SiS964 appears somewhat better.
