Correction to my previous… When I return and hook my system back up I plug all the MacBookPro cabling in INCLUDING the thunderbolt cable while the computer is off, THEN re-plug the LaCie Hub power back into the LaCie and THEN turn on my laptop. The auto on/off function of the LaCie acts normal from then on.
The problem I would have is if I left the LaCie plugged in to power and took the laptop on the road, when I hooked the laptop back up and turned the computer on everything would be normal. But when I shut the computer down the LaCie Hub would stay on so I would have to pull its power and re-plug at that time.
Thats the only issue with it.
I have been transferring footage to the RAID for about 8 hours now and am getting a very non-scientific transfer rate of about 1 gig every 8 to 15 seconds (as measured on the stopwatch!) depending on the source (Expresscard eSATA or FW800 drives. So as I have no experience with RAID I just figure this is a consequence of my choosing RAID5 which I have read slows writes as it calculates parity. My speed seems to be hovering around 100meg per second, though.
I will be interested to see how the RAID performs when I get to edit some of the footage and playback a timeline through a Matrox MX02.
