I have 7 hard drives that I want to be made available to my primary computer through the network, probably a direct computer to computer ethernet connection. What's the difference between, say, loading Fedora Core onto the system with 7 hard drives and running Samba, and loading FreeNAS onto the system with 7 hard drives? Which would be faster? I do a lot of photo editing so I want write and read speeds to be maximized. Random access isn't as much of a requirement.
