-T
Perform timings of cache reads for benchmark and comparison
purposes. For meaningful results, this operation should be repeated
2-3 times on an otherwise inactive system (no other active processes)
with at least a couple of megabytes of free memory. This displays the
speed of reading directly from the Linux buffer cache without disk
access. This measurement is essentially an indication of the
throughput of the processor, cache, and memory of the system under
test. If the -t flag is also specified, then a correction factor based
on the outcome of -T will be incorporated into the result reported for
the -t operation.

-t
Perform timings of device reads for benchmark and comparison purposes.
For meaningful results, this operation should be repeated 2-3 times on
an otherwise inactive system (no other active processes) with at least
a couple of megabytes of free memory. This displays the speed of
reading through the buffer cache to the disk without any prior caching
of data. This measurement is an indication of how fast the drive can
sustain sequential data reads under Linux, without any filesystem
overhead. To ensure accurate measurments, the buffer cache is flushed
during the processing of -t using the BLKFLSBUF ioctl. If the -T flag
is also specified, then a correction factor based on the outcome of -T
will be incorporated into the result reported for the -t operation.

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

やっと、udma5が使えるようになりました。

気づかなかったけど、VIA VT82* South Bridge 使ってる場合、
RedHat7.2、付属のドライバ(via82cxxx.o)ではudma3/4/5が使えないみたい。
より新しいカーネルのドライバを使うと良いと思います。

(RedHat7.2のカーネルソース持ってる人は、
linux/drivers/ide/via82cxxx.c の436行目、
via_80w = 0;
っていうのをコメントアウトするとうまくいくかもしれません。
見たかんじ、これがケーブルの検出を無効にしてるみたいなので…

しかも、ATA66になってないよ

MPG3409AT-EF も持ってたけど、やっぱり 15MB/s 位だったな。
やっぱりサウスの責任かなぁ。
CPU は k6-III と Pen3-700 で hdparm -t の数値ぜんぜん
変わんなかったんだよね(サウスは一緒)。だから CPU は多分かんけいない。

hdparm -I で見ると /dev/hdc は udma4 に * が付くので ATA66
になってると思う。/dev/hda のほうはケーブルが ATA33 用なので
udma2 のままでいい。
実は ATA100 用ケーブル繋いだ /dev/hdc を udma4 で使ってみて
ぜんぜん改善しなかったので /dev/hda のほうを udma4 化する気力を
なくしてる ...
