Apologies ahead of time for the volumes of info 
It's definitely much newer than the disk I'm comparing it to (Western Digital 200GB,8M cache - WD2000JB vs. Unknown (I think it's a Maxtor, but it's a Hitachi model drive, 40GB)).
/dev/root = /dev/hdb = Hitachi drive
/dev/hdd = WD2000JB
Seems like the newer drive should be faster, but it's not. Ideas?
