Yep, that simple. HDDs plugged into powered hub. Hub plugged into PS3. I really haven't tried to get at the PS3/drives from my wireless laptop, but I suspect it's possible in some form.
On the 320 GB I have music, pictures and DVDs. The 750 GB drive is dedicated to DVDs.
When I turn the PS3 on, each HDD shows up and it's simple navigation after that.
The other thing I like about the solution is that it's a simple thing to move the HDDs between the PCs I have and the PS3. Plus, I can turn off the PCs when I'm not using them. Simpler from a network/media software perspective as well.
