So I'm having a hard time deciding what to do with my two open HDD bays in my Mac Pro. I know I want to add more storage, but I'm not sure if I should use Raid0 or not. I store most of my media on a server but wanted to store the following in my MacPro and would need more hdd space. iTunes Library Pictures Bootcamp - obviously can't store in server Scratch drive - would write handbrake encodes to this then transfer to server In all I'll need around 1.5tb I already have a 1.5tb drive and would only consider buying another to put them into raid0. Should I bother with raid0 for the increased speed or just use the 7200RPM 1.5tb drive I already have? This is all for my personal use but I like my system fast. I have a time capsule to use as a backup if needed.
