[hardware] Tagged Command Queuing or Larger Cache ?

Howdy Crew,

I am about to buy a new hard disk for my FreeBSD work station.
Since FreeBSD's ATA drivers implement Tagged Command Queuing and IBM make
the only ATA disks that implement tagged command queuing ( ie since the 60GXP 
family ),
an IBM 40GB 120GXP "looks like" the best solution.

However, my question is:

Do the benifits from a having a larger disk cache such as the "WD 40GB 7200RPM 
w/8MB Cache"
has, outweigh the benefits of Tagged Command Queuing ?

Thanks

 - aW
