Something wrong with my disks?

I've been experiencing momentary absolutely awful performance in my WHS recently, decompressing a simple 500mb archive can take a full 3-4 minutes and sometimes while browsing the shares everything just freezes cold. This can last anywhere from a few seconds to almost a minute.

So far as I can tell it isn't a network limitation, what are some tests I can run on my individual disks? I ran HD Tach(no idea if it's any good) and it shows some really incredible downward spikes in read performance on all but a few drives. The drives that I believe are having issues are connected through some Sil3124 and one Sil3132 controller. None of the offending drives appears to be connected via the motherboard headers.

Any help or suggestions would be really appreciated.
