Confused, I am...
Currently I have 2x 500GB WD original fit (Caviar blue?) plus a Caviar Green 640GB. The first 500GB drive is my system and applications drive, but also has a lot of data on it that I would like to move elsewhere (emails, documents etc, that I need to keep to hand) as its now over 400GB; the second 500GB holds all my photos and is nearly full (keen amateur, like others on this forum lots of big RAW files); the 640GB is used for internal backing up of crucial data (iTunes etc) and temporary odds and ends. I also use Time Machine to an external 1TB drive.
My questions:
1. A lot of apps seem to insist on loading to the system drive, they won't allow the option of living elsewhere (I get the "no entry" symbol on the other drives); is this something I have to live with?
2. If I can move the apps to another drive, what effect can that have on the running of the Mac, in terms of speed, access problems, OSX mislaying things?
3. If I can't move the apps, I'll be needing a much bigger system drive. From this forum it looks like Caviar Black is the way to go for the system drive, but now they're SATA 6 at the 1TB size; I know it's supposed to be compatible, but is there any downside?
4. And is there any point putting a fast drive in as the system drive if I'm using a slower drive (eg Caviar green) for my data; particularly for my photos, using Aperture?
5. I have to run Windows for a couple of work-related reasons (the software won't run on a Mac); at the moment I'm using Virtualbox, which is fine, but I'm thinking of dedicating a hard drive to it (partly so I can easily get rid of the whole thing if I want to!) I'll probably use the existing 640GB for that. Which leads to my last question; given I will have 2x 1Tb drives, possibly, what would you recommend putting in that fourth bay?
I don't have the RAID card.
Phew! Just writing all that down has increased the number of circles I'm going round in. So any help will be very much appreciated, thanks.
