View Full Version : ATA controller card

06-27-2001, 08:54 AM
I have two IDE drives set up on my G4 533, here's a question: could I install an ATA controller card (PCI) and hook up another 1 or 2 drives? Would it vastly decrease performance ... if it worked?

A IDE/ATA 66 PCI card should perform the same or very close to what you rstock ATA/66 controller can do. The case will handle 4 drives on the bottom bays. Since only one drive per channel can do anything at any given time, you may see an increase in performance. I would install both as master drives on their own channel.

The fastest IDE/ATA drives (ATA/100, 7200RPM) will only push about 30~35MB/s max sustained. So the full potential of the ATA/66 bus is not used.

Also remember that when you install drives on the ATA PCI card, they are acting as a SCSI drive. You can not swap drives around from the stock bus to the PCI card without reformatting.

The ULTIMATE drive setup would be to get 4 x15 Cheetahs (I hear they are coming out with a 36GB model) and a dual channel ATTO U160 card, cables, SoftRAID, terminators, etc.. This can run $2600 and up, but ya gotta pay to play http://macgurus.com/infopop/emoticons/icon_biggrin.gif

You should only spend that kind of money if
A) It can enable you to make more money - its your work system
B) You dont know what to do with your money.

Oh but you can swap drives around without reformating and
with no loss of data if you use Intech's Hard disk speedtools!
I used it works great! The lastest version even works with OSX! later

So maybe it adjust the 'drivers' based on where the drive is plugged into? Or maybe there is much in common between SCSI & IDE/ATA?
