How many SATA devices can be used with a single controller?

Is there any limitation about that?

Thanks

Yes. You can only attach as many SATA devices as the controller has
ports. A two port controller could only support two devices. It's
not like USB, where you can split ports using a hub. SATA is a
point-to-point interface.

I believe current SATA controllers can only control 1 SATA hard drive per
controller.

Not just current, but for all time. SATA is a point-to-point cable
design. Period.

The temporary (I hope) constraint is that the only SATA devices are
HDs. Some day, maybe, optical and tape devices will also use SATA;
then we can wipe out PATA. I'd hope that FDs would also sprout
SATA interfaces, but FDs will probably die first.

Clueless, as always.

So all IDE host bus adapters (controllers) are 2 drive designs? Wotanidiot!

Lack_of is not the same as a constraint.

Plextor will have the first SATA DVD burner on the market.
