While searching for a way to store a couple of terabytes on the cheap (not really possible I know, but I'm seeing how low we can go), I ran across the product linked below. While it currently only works with IDE drives and I'd much rather use SATA drives, the SATA device is coming soon and should cost about the same when it does come out. The beauty of the system is that you only need one parity drive across all 12 drives. So, instead of losing one drive for every 4 drives as my RAID is set up now, you lose one per 12. A much better ratio.
Also, you can add drives at any time without problem. For example, to start, let's say you want 1 TB, just buy three 500 gig drives, plug them in and you have two drives of storage with one drive for parity. Then, if you want another TB, just add two more drives. All the way up to 12 total drives for 5.5TB of storage. That's pretty damn cool.
$1299 for the case + 12 x 370 = $5739 or $1.04/gigabyte. Now that's damn good.
Just for illustration, let's go cheap and get a $150 enclosure for 4 drives. With one drive for parity, you have 1.5 TB. Total cost: $150 + 4 x 370 = 1630 or $1.08/gigabyte. Well, not quite the difference I was expecting, but to get to 5.5 TB, you need 4 enclosures and 15 500 gig drives ($1.11/gigabyte - adding the sixteenth drive gets you to 6 TB and back to the $1.08/GB).
I'm not quite sure how you'd hook up those 16 drives to your home theater system - maybe you can find a 4 drive network attached storage system, but that'll run you more than $150 for the enclosure, or maybe you want to put 4 PCI SATA adapters in your system and not many boards come with 4 PCI slots any more (plus, you'd need a PCI slot for the TV tuner, so it's getting even harder to work out).
There's a great thread over at AVS Forum on the Lime Tech box as well. I'm only on page 5 out of 22, but it's provided a wealth of
information. The box is pricey, but seems to be worth it. Easily scalable to 5.5 TB is awesome. Even though it's not as slick as the
8 drive system from A-Tech, since the Lime Tech machine is accessed through GigE, it can be placed out of sight and out of mind. Very nice.
