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
