old EIDE HD + UDMA 33 HD on a UDMA 66 board

hi, all

I decided to keep my old EIDE WD hard drive as a backup
with a new UDMA 33 IBM deskstar on a Intel CC820 motherboard
which has a UDMA 66 capable cable.
Since this UDMA66 80pin cable is backward compatible with all
PIO and UDMA modes, I know this setup will work.
My question is "would it be any performance loss for this
setup?"  I mean, would the new IBM be affected by the presence
of the legacy EIDE drive ?
Maybe it's obvious to some of you guys, or it's been answered
somewhere, but could anyone out there shed a light on this?
TIA,

Wonil
