There's nothing new or magical about the FlexRaid setup. Dedicated parity drives were common 35 years ago; they just got upgraded into what you call "traditional raid".
It feels like we're arguing past each other. You are telling me how much more security a second deadbolt on the front door will add, and I'm telling you to address the windows and side doors first. That's what I mean by "supporting infrastructure"
Good grief Eric.
Please, PLEASE educate yourself before spewing any more nonsense.
NOTHING you have argued is correct....
Let me start you off with a easy example/tutorial.....
Person 'A' has an UnRaid set-up with 6 2tb drives and one 2tb parity drive.
All six drives are full of Blu Ray movies that 'A' has spent months ripping and burning
to the Unraid array.
Suddenly, Drive #3, (a 2tb drive full of Blu Ray movies) dies. Oh No! What to do?
Thanks to UnRaids' parity protection scheme, all "A' has to do is pull the bad drive #3, slip in a new
2tb drive, and sit back as UnRaid reconstructs what was on the failed drive!
Imagine that! No reripping all the Blu Rays, no trying to figure out what data was lost. No more work than
plugging in a new Hard Drive and watching UnRaid (magically) rebuild by itself.
THAT is what Flexraid/UnRaid is....nothing more, nothing less.
Your ridiculous comments about data management and second parity drives making a system 'less'
reliable show you have no clue what you are talking about.
If you have some 'facts' that there are indeed problems with Unraid/flexraid in the way of
'windows and side doors' that are more of a risk than hard drive failure I would welcome
hearing about those issues.Edited by dan4081 - 9/17/12 at 5:21pm
