なるほど。どーりで…
さすが世代が違うって感じですねぇ。

うは、上がってるし。(w
最近組み立てた AthlonXP 1600+(FSB140 駆動) / PC2100 Registered では、
確か cache read が 200MB/sec. ちょいくらいだったかな。
今は Windows しか入ってないんで、詳細なデータ出せなくてスマヌ。。。

hdparm is a Linux utility for viewing/manipulating various
IDE drive and driver parameters. Most systems can benefit
from improved performance using a command sequence similar to this:
#!/bin/sh
for d in /proc/ide/hd* ; do
if [ `cat $d/media` = 'disk' ]; then
hdparm -qm8 -qu1 -qc1 -qd1 -qW1 /dev/${d##*/}
elif [ `cat $d/media` = 'cdrom' ]; then
hdparm -qu1 -qd1 /dev/${d##*/}
fi
done
