@Dashrender Better I/O performance over consumer grade?
Yeah If I just stop and think about it - the answer is when the situation calls for what it provides.
I guess I'm still a little stuck in two years ago, when SSDs were still flaky at the consumer level. I purchased three SSD drives back then and one of the three did fail. I've seen Scott say and read elsewhere that SSDs are significantly more reliable today even just a few years later.
I remember reading articles where some early adopters really dogged on SSD's but failed to mention that they were on the bleeding edge and those issues should have been expected. But 2 years might as well be 2 centuries in the progress that has been made with SSD technology. Just take a look at some of the developments that SanDisk for instance has made in the area.

Even two years ago they rocked. The myth and rumor around SSD is so strong that it seems like issues were that recent but it has actually been much longer.

Seems like it's going to be like RAID 5, something that's hard to shake loose from people's thoughts.
-
And then when you move to SSD, RAID 5 can make sense again. Lol

Not worth still skipping it and sticking with RAID 6? I take it URE's are enough of a non issue?

So far, URE doesn't conceptually exist in the SSD world. It's a spinning rust issue.

RAID 6 would keep other benefits, of course.

What about DAC? isn't that still a factor with any parity RAID?

Yes it is. However, it is suspected that much of DAC is a second order consequence of URE. And also a lot of DAC is believed to come from drive vibration. Both things are fixed with SSD. So it is believed that the likelihood of DAC is lower.
