I googled on "82801GBM/GHM slow" and found a lot to read.

Is DMA for this drive enabled? It seems that some others didn't have
it enabled by default, or maybe at all. I didn't real the threads very
far.

hdparm -d1 /dev/sda

I think hdparm works for most SATA drivers. man sata to see the other
things you can check in terms of configuration.

Clearly, since you see the same thing in a console with X never having
been started says it's not a GUI issue.

Hope this helps,
Mark
