Hi, Right now I only have a 250gb hd in my mac pro but will be ordering a 750gb soon and a couple more down the road. But for the time being I'll just have my 250gb and the 750gb. What I want to do once I get the 750 is use it for OS X and the 250 for Windows. Would it be difficult to have everything copied over from the 250 over to the 750 and make that the boot drive? I'm sure it's a simple matter of cloning but I just thought I'd ask. Also, I've seen a lot of 750gb hard drives on New Egg that have good reviews so I'm having trouble choosing. I don't know much about pros and cons between different hard drives.
