@scottalanmiller wow, even in that explanation is seems like RAID 10 over RAID 6... except I suppose because you can better leverage your total diskspace. Is that the primary motivation?
So to summarize:
RAID 6 = Good backup solution due to higher use of available disks in the array (although consider 10 depending on the size of the array... larger array pushes you to RAID 10)
RAID 10 = Good for production use -- high availability... faster disk failure recovery, etc...
RAID 0 = For total high performance (we leverage this in our business for specific uses)... requires duplicate array for any form of redundancy/availability... -

Correct, the sole motivation for RAID 6 is that you can get more capacity at lower cost and quite often, that is a really big motivator. Speed and reliability, once you have "enough" might not be worth losing additional money over. And with moderately sized arrays, the capacity benefits of RAID 6 can be quite significant. Like in a 12 disk array.

If you have a duplicate array, then it's really RAID 01.

In what scenario would you personally use a raid 6 @scottalanmiller? Double parity is a huge penalty for cheap redundancy. Low capacity low iops server that only sort of matters?

Any scenario where it meets the minimum requirement and the driver is lowering the cost of capacity. I'd almost always use it in backup and archival storage where I've not moved on to RAIN.

The Netgear ReadyNAS line has three desktop models that will take eight drives- I don't know if this would help any..
- RN628X - 130tb
- RN528X - 130tb
- RN428 - 80tb
I have a ReadyNAS 4 bay, runs great, little maintenance - thought I suppose I could / should do more with it. It mainly just sits as I am slow working on the project of moving my media over to it.

RN628X
Diskless, that unit is $2,082.27. That's limited to eight bays. Going with an enterprise server, like an R510, would be under half that price with far more power and flexibility. And not limited to SATA.

I just did a quick Xbyte for this. Really beefy processors (for the class) plus 6TB usable RAID 10 array for $3,000.

With SAS drives?

You don't need really beefy processors nor dual processors. Look at smaller, single procs.

No, SATA. SAS would have bumped up the price a bit.

That's odd. normally it's the same or cheaper.

If @markl decides to use a server like R510, would you recommend installing a hypervisor and then setup a VM has a NAS server? -

-
Virtual. And I think I mentioned that buried in one of my posts about it. Or maybe it was the other thread that this split off of.
KVM, Xen or Hyper-V all work great here. Physical wouldn't be horrible, but no need for it.
