After seeing a story about some NAS hard drive thing, I was intrigued. I searched MR and wiki and Google, and I think I understand what it is - a networked HD. I'm sure it's much more complicated than that, but I'm not sure how. Anyway, I was wondering if someone could help me understand what they are and how it could be used in a home setup. We are not as wired as some folks here, but I was thinking to use it as a back-up drive for our two computers and one external. I found freeNAS.org and that just confused me further - I take it that some sort of mini-OS is loaded on the computer that has however many HDs that you have stuffed in there, and you can make a RAID. Or something. And, I rememebr something about how it doesn't take much of an older machine to run the NAS. Something that has a 95 MHz processor or something. I'm so fracking confused. I'm just trying to figure out the uses of a NAS at home and when it is beneficial to have one. Then I can figure out how on earth I go about setting one up.
