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 ?
