Whats the cached transfer rate matter. Its the overall throughput that matters.
With a Buslogic BT-958 and a Seagate Barracuda (ST32171W) I get just over 8.5 MB/s with hdparm...no, thats not the cached rate. Unfortunately it didnt come cheap
BT-958 $241 ST32171W $695
IDE seems to be the right choice for the everday workstation. I get great throughput with the Quantum Fireballs 6.50 MB/s. $252
But for a small server or heavily used work station an Ultra Wide bus of fast drives kicks ass.
One of these days I'll have find the time to stripe two of those ST32171W's:)
Not that this affects kernel development:)
