Tagged Command Queuing or Larger Cache ?

[popo]

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

IIRC the 120GXP and the WD1200JB (Both 120GB models) had similar, if not identical performance. It seems that IBM builds the fastest HDD's right now, next to WD and their 2000JB. I'd reccomend waiting for the 60GB 180GXP, that should be a cool, quiet, fast sollution.
