Promise Pegasus R4

You can buy an empty one and fill it yourself with the drives you need.
It's the only Thunderbolt device I could find. Others are USB3.0.
However, it's a lot cheaper to buy a NAS and connect it to your gigabit-network using ethernet-cables while your computer is also connected to your network using ethernet-cables. It'll be blazing fast too.

Have a look at Datoptic.

Their stuff actually gets really good reviews, and it's all hardware. Very nice. And extremely well priced.

Not to sound like a dick but did anyone read the part about GOOD PRICE, so far the only recommendations I have seen are around $800USD and more. I must be in the wrong tax bracket if that's what you guys consider a good price

TB/eSATA/USB3 for $800 is a steal...
Not to counter-dick, but you do realize you still need to fill whatever bay you get with decent hard drives right? Those are going to cost you three times that. You really shouldn't be using standard drives in a RAID5. WD RE drives or Hitachi Ultrastars is what you are looking at.

I agree that it sounds very expensive, but I Agree with Jester. $800 for TB/USB3/eSATA with a built in RAID controller is awesome. When it comes to big data storage, you do have to pay to play. I've been looking into this for over a year, and have gone back and forth with buying a pre-built solution versus building a NAS, and for me I really want a DAS like this, and I want something rock solid. I'm also paranoid, so when I build mine I'm going to have to double up. So I'm looking at
$850 enclosure
5 x $200 (at least) HD's
Total = $1850
Then double that, for double storage = $3700. Ouch. But that would give redundant 15 - 20 Tb storage.

Define good price, and more people may be able to help guide you to a solution.
Check out ebay for used large capacity drives, and then ask yourself why such a large drive is being offered at a lower price than a new drive.
there are deals to be had for 1TB, 2TB, and 3TB bare drives, but 4TB drives are still a premium. Have seen new 3TB for $140 and 4TB for $280.
Time to move into that higher tax bracket to get what you want.
Agree... you really should have enterprise drives for RAID. They have better command queueing depth and other features that can prevent issues.
My Pegasus R4 comes with four 2TB Hitachi Ultrastars. They also warn against using non-enterprise drives... and have a published drive compatibility list.

To the thread starter:
As has already been pointed out "enterprise drives" are recommended.
If you can live with cycling/rotating individual drives, the Seagate GoFlex Desk Thunderbolt adapter is great & has a secondary TB pass through.
It also works great with 3.5" & 2.5" bare drives (not necessarily enterprise grade) as well as SSDs, which you can cycle/rotate on a regular basis, using CCC/SuperDuper as well as TM.
Hope this helps,
JF

Lacie just released this. 5 x TB storage.
http://www.lacie.com/us/products/product.htm?id=10607
It's actually pretty damn well priced!
edit: bah, that sucks. No raid 5. FAIL!

Wow, with user-servicable disks! Too bad it can't be ordered "empty". Otherwise I'd probably jump on that one! Stylish, elegant, seems very good and easy to upgrade!
A shame it doesn't have RAID 5 but RAID 1 is pretty good too, although you lose more storage.
Not if you're looking for performance. those RED drives like like server grade Green drives. Variable spindle speed rotation isn't something you want in a high performance RAID.
On the product page they list the different RAID configurations, you can view them on the link that was posted in this thread!
Ahhh. Thank you, I went to the product page and viewed the configs. That makes sense, I hadn't considered using multiple smaller configs. I think I'd still opt for the Datoptic thunderbolt RAID015 unit posted earlier in this thread.
**** man, the lack of USB3 just kills me on my macs. To get comparable speeds it's such a big upgrade to go to thunderbolt that it just adds hundreds and hudnreds to the price. That datoptic unit is $200 more expensive in thunderbolt, so if I got two of them, it's $400 extra. For that I may as well upgrade my Mac mini server to a new unit w/ USB3 and sell the old one. I'd probably come out ahead that way.
Not really much of a premium. Sell the drives you don't want on ebay, then stuff with you own drives.
Or wait for the typical reseller discounts when it ships in volume.
Compare to the price of an empty j4 or drobo.
Where can an empty Pegasus R4 be purchased?
I have a Drobo full of drives I would like to transfer to a R4.
