Hard drives causing painful slowdown
So my hard drives (I have two 160 GB 7200 RPM ATA ones) are becoming a problem. Whenever a lot of data is being written to them (i.e. whenever I copy a large file from one drive to another or from a network mounted share to one of my drives), my computer basically grinds to a halt. Music starts skipping, my wireless keyboard sends nonsense signals when I type, and all sorts of unpleasant experiences assail my fragile little brain.
This happens even if I use, say,
so I assume it's not a processor problem. The benchmark of hdparm is as follows:
nice -n 30 cp drive1/movie.avi drive2/
and as far as I know, those numbers are pretty good.

Timing buffer-cache reads: 2196 MB in 2.00 seconds = 1097.62 MB/sec
Timing buffered disk reads: 22 MB in 3.04 seconds = 7.23 MB/sec
Can anybody think of what might relieve this awful bottleneck? This is a Slackware system with kernel 2.6.7.
