Sorry, I stand corrected - I actually checked on my laptop (2.5"
5700RPM HDD) and I'm getting:

patrick at laptop:~$ time (dd if=/dev/zero of=/tmp/testfile bs=1M count=1000; sync)
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB) copied, 21.6167 s, 48.5 MB/s

real	0m26.375s
user	0m0.008s
sys	0m2.972s
patrick at laptop:~$

Forgive me if this has already been asked, but you've checked DMA is
turned on on your HDD?
