I'd like to have a large external raid. 4 drives, large capacity and reliability are more important than speed. However, it doesn't seem like there are a ton of options out there and the price of many leaves something to be desired. If building a second computer and running an internal raid is what I have to do for backup, then so be it. Am I missing a prize out there? Can anyone point me to a reasonably priced large external solution? "reasonable" in this case is simply less than a computer w/raid card.
It's a trickier question than one would think. I don't have an exact ceiling, I'm just not looking to buy a device that costs more than a computer w/raid card that I could use as external storage. Any number would be arbitrary, but I guess 500ish (US) might be a good number.
Well, for a TB+ NAS, your going to spend around 700 bucks. Before you could buy them, I was using freeNAS and Linux zero raid to build my own boxes. For the money ( assuming you have gigabit networks) I just think these new NAS systems are pretty good. They are quiet, cool, and safe with raid 5 options. You could also get an empty setup from Buffalotech or any Intel, and add large drives in a spanning schema as you progress. You'll save money over time by adding extra (up to 5 for most home NAS solutions) as they drop in price.
Buffalotech and Techus are the two NAS makers that I see reviewed on a regular basis. They both have NAS\SAN models that have the Tom's Awards attached to them. Personally I liked the Techus N5200, it comes at a high price, but it's got everything you need in it to make a nice storage server.
