...need quiet drives or the wife will get angry. I'm still surprised that she's okay having this giant mac pro and 30" screen in our tiny living room, but it certainly does help that they're so pretty. I looked through this thread discussing the WD Black drives...it's a few months old, would people still recommend those? While they can definitely be had through newegg for pennies, I don't mind spending a little more if it will get a quieter/more reliable drive. These will be used to do autocad & photoshop (oh, and, of course one of them will be a bootcamp drive, since autocad unfortunately isn't a native mac app), primarily, so speed is somewhat of an issue, but it's not like I'm doing gigantic 3D renders. One drive will be a scratch disk for PS, one drive a time machine backup, and one a data drive...at least, that's what I've considered at this point...still trying to figure out how I want to do my total household network backup...currently, external drives are connected to my home theater-powering mac mini, and our laptops time machine into that, using 'home and away' (awesome app, by the way). I'd like to keep that system as is, and maybe just have the mac pro as a completely separate system (my 'work' system), and have its time machine backups self-contained, and probably backed up offsite somehow. i think I've given enough information here....let me know what drives I should be looking at...thanks!
