Need Help Choosing a Data Storage Solution

Good Evening. First Post.

I have a large amount of information, roughly 1.5TB, and in its current state, any single hard drive failure results in a loss of data, as much as almost 2/3. I want to migrate this data to a system that is 'non-volatile'; meaning that I can safely lose a single drive without losing data.

I did a little bit of searching throughout this forum and on my own, and I still am at odds what to do. My criteria is this: I want a small, compact solution that is expandable, reliable, and relatively easy to maintain. This system replaces having a bunch of drives in my main rig, therefore I prefer an interface that maintains that "local" quickness.

The ultimate goal is to make a system that is inexpensively fault tolerant with an emphasis of ease of maintenance. The budget is $500.

The Drobo seems nice: its compact, very easy to maintain, straightforward, and 'non-volatile'. I like that you can mix-n-match drive sizes, and its effortless to understand. However, Firewire 800 and USB2.0 doesn't seem all that quick, and I keep hearing that its very slow to use.

HP MediaSmart servers seem nifty in that I get a full computer system in a small package. Like Drobo, I can use different drive sizes, but I can also selectively add protection using duplication. However, I don't like the idea of having to maintain ANOTHER Windows machine JUST to store my data, duplication uses more space than parity.

There are also a few more options, like RAID 1, RAID 5, unRAID, FlexRAID, etc, and all of these have benefits like >4 drive capacity and more flexibility, but all seem to have severe drawbacks. unRAID looks complicated to setup, RAID requires matching drive sizes on the same controller and I can't expand it, and all of the configurations I find seem far too large. I can't find comparable small form factors similar to the HP or Drobo.

What are your thoughts? Thank you for your time.

-Cool-
 
Inexpensively fault tolerant is a bit of a oxymoron I think. Now do you want a DAS (external Drobo) or NAS (HP Mediasmart) or Server (RAID 5 file server)?

Now does that $500 include the hard drives as well?

Oh and you can expand a RAID array if the RAID controller supports OCE or Online Capacity Expansion. Most true and good quality hardware controllers support that feature.

WHS isn't that hard to maintain. After the initial setup, you really don't need to pay attention to it. It's pretty much low maintenance IMO. Oh you might also want to take a look at the Acer Easystore Home Server for $350:

Size/expandability wise, thats all up to you. If you want small, four drive is about the max for a small compact server (i.e Drobo, HP MediaSmart, EasyStore). If you want lots of expansion, a file server is your best bet.

And for my standard speel on the Perc 5/i card:
If you don't mind buying used hardware with little or no warranty, you could buy a Dell Perc 5/i card off eBay for ~$100 or so plus two of these SFF-8484 to 4 x SATA Cables for ~$25. Thus, you get 8 ports and a true hardware RAID controller for around ~$125 or so. Add a battery backup unit for ~$40 and you're set in case of power outages as well up the performance. Not a bad deal considering that a new true PCI-E hardware RAID controller is around $300 (Areca ARC-1210) for 4 ports.

EDIT: As of May 2009, it seems that you can find many Perc 5/i cards with the BBU and PCI bracket for $120 and under. Excellent price!

But those Dell Perc 5/i cards are finicky about motherboards. It will take up PCI-E x16 slot if you don't have a PCI-E x8 slot.
