For something that has such a high footprint, I prefer getting hard media; you don't have to deal with data damage due to interruptions and slow downs (of course there are other issues that can be just as bad, but....)

Just got P8 today, and hopefully will have it installed in a couple of weeks (I still have to get the rack for the office. No place to put the CG box and its 4u chassis except in a rack). I should have at least some of the rendergarden back up by september, so I can't wait to see how the network rendering goes....
