I do understand Drobo but here's my question? You buy regular 3.5 sata hard drives, the ones that can die/crash and stuff them into this machine.
Great it can hold four. Ok here's my dillema with Drobo.
What if those four sata drives die out because of old age? They are the same ones that are prone to crashes just like PC's.
What happens to all of your back up info if the hard drives fail?
It's almost no different than just buying Seagate or WD external hard drives. Except you can stack them with superb ease.
Am I missing something?
Time Capsule seems more reliable than this thing. But I could be wrong.
If I am ignorant then please explain it to me. I am looking into back up storage at the moment so I want the best.
With the Drobo, it can recover all of your data if one of the drives fails. It might even be able to recover if 2 fail (maybe if you have 4 hard drives in there, I don't know).
Hard drives die, but the chance of more than one dying at the same time is one in a million. So if one craps out, the Drobo continues on as if nothing happened (well, it's doing behind the scenes stuff, but as far as you can tell, nothing changed), and you replace it ASAP to make sure your data is fully protected.
It is most definitely more safe than other external hard drives or a Time Capsule, because if that drive goes out, you're up a creek. The Drobo won't help you if all drives go out at the same time, but nothing will. If your data is
that important, then you need to be backing it up to something else, whether it's online storage, DVDs or even more hard drives and stored offsite in addition to the Drobo.
They have a video on their site that demonstrates how Drobo works, I'd recommend watching it.
Re: the FW Drobo, unless you have an absolute need for Firewire, save some money and get one of the original USB ones. I was holding out for the Firewire one too, but decided to save myself $150 and buy a USB2 one from Newegg last week. USB is fast enough for my needs.
