My guess is the lack of cache on the Celeron but I could be totally wrong.
I've got the same 10G drive in my box and it absolutely flies under linux.
BX chipset.. whereas it looks like you've got the FX chipset? That could be
another reason. FX didn't have UDMA support.

Try -c1 -d1 -m16 -W1 with hdparm and see what it does.
Make sure nothing important is on that drive beforehand.

It's the fastest IDE drive I've ever seen.

Which is worse, ignorance or apathy? Who knows? Who cares?
IBM: It may be slow, but at least it's expensive.
Linux: Get it up, keep it up. Viagra for PCs.
