Hi all, this is my first thread here and it's great to be part of the community. I just ordered a MAc Pro (3.33 + 5870) Waiting to delivery OWC- 16gb Ram My question is about my HDs layouts. The use is basically for 1080p movies, watching and storage. (20-30gb each movie). I'm moving from a hackintosh. They are all in the itunes library right now spammed to several HDs using TuneSpam app. The perfect scenario would be just one big HD for my itunes movie library, not using the TuneSpam app. I know that raid could archive that goal with several HDs appearing as one in OSX, but i never used raid before, and as you will see below, my HDs are mostly different from each other. Is there a way to show several HDs as one without using raid? My HDs: 1 x Crucial SSD 256mb -- boot, apps, home(Spammed by TuneSpam) 2 x 1,5 Tb Seagate 7200rpm 1 x 2 Tb Seagate 7200rpm 2 x 2 Tb Seagate 5900rpm I'm doing backups for everything but movies (just 200gb). Thank you very much for your time.
