Recently my Seagate 2tb Green HDD crashed running WHSv1. So I decided to buy one of the new WD RED 3tb drives and try WHS2011, without thinking that my Atom system doesn't support GPT booting. So I can't use it for the booting the OS without losing 768gb of storage space.
My question is should I use the replacement Seagate 2tb Green HDD i'm getting for the OS, or should I use a spare WD Black 250gb Laptop HDD i have sitting around. I'll still be using the WD Red drive for data. Which drive will give me better performance? I only use my server for file sharing and torrent downloading, and I don't have much data so the difference between 3tb and 5tb doesn't matter to me at the moment.
