Shopdog,

The technology is different between an ATA and a SATA. The later 
transmits data in a string, or serially. The ATA transmits the data in 
a parallel fashion -- completely different technologies.  I think the 
STAT drive will probably function on your Mac but you will need to add 
a serial disk controller card. It will not communicate with your 
existing ATA interface.

On the plus side, SATA is faster and more efficient, and probably the 
way of the future. For a long time, all printers had a parallel 
interface, but as the processor speeds have increased, almost all 
printers now days are serial (USB). One can probably expect a similar 
trend on drives. You see these SATA drives frequently on fast PC 
machines. But they do require a fast CPU and might put a larger 
processing burden on the computer?  That is a guess on my part and 
perhaps folks smarter than me can comment on that.
