Al, my apologies for my vague question :P. I would like to know if a Raid configuration is a good choice for me since one of my hard drives is only 80GB. I tried a raid configuration but when I mapped the drive on windows7 the Raid capacity was showing only about 70GB . Right now I decided to run FreeNas7 and have mounted the two drives as separate shares. With this configuration I will have to back up my files to an off site backup service, which I should be doing anyway. Thanks for taking the time to read my post.
