Boy, that sure kills my IDE drives!

Here's an old SuSE 6.3 with a 20GB 7200RPM IDE IBM drive:

> time dd if=/dev/zero of=testfile bs=100000 count=5000
5000+0 records in
5000+0 records out

real    2m3.151s
user    0m0.710s
sys     1m36.770s

And here's a new Sid system with a 60GB 7200 IBM drive.

$ time dd if=/dev/zero of=testfile bs=100000 count=5000
5000+0 records in
5000+0 records out

real    1m9.297s
user    0m0.190s
sys     0m52.100s
