The good starting point is to look for if they present good, solid logic for their reasons, or if they just tell you to do it their way; or they make ridiculous claims to cover for bad decision making like saying that "every company is unique." As if Russian roulette is smart "for some people", since everyone is a little different. Obviously some things are dumb for everyone.
We would hope that someone would chime in and challenge bad advice, but you have to understand that no everyone is as smart as you are. SW is a perfect example of how misinformation reigns king. The people who are the loudest are often the most incorrect.
But anyone asking for advice from people they have not tested should be looking for signs of knowledge versus bluster or trolling. You can't always tell, but expecting people to come to your defense and just accepting bad advice just because they do not isn't good adulting. At least attempting to look for signs of incompetence is important in any situation like this.

I feel like almost all of SW can be summed up like this now...

How do people keep repeating such an obviously incorrect myth about software RAID?

@scottalanmiller I posted that link in the other topic that you posted another SW link about.
I thought it was funny to. "Software RAID is never recommended". . . um no FakeRAID is never recommended. Software RAID is used and recommended all of the time for people and orgs that can maintain it.

What type of maintenance is required for real software RAID?

Maintenance as in "oh shit a drive died, what do I need to do?"
Because hardware raid makes this stupidly simply, pull the drive, install new drive let it auto rebuild. Software raid requires you to mark a drive as bad, eject the disk from the array, shutdown the server, replace the drive, mark the new drive as a replacement and then rebuild the array.
Just different management/maintenance process.

I think everything but shutdown the server. I was able to replace a drive hot with MD-RAID on my little test box.

@dustinb3403 Ah, gotcha, I didn't know if there were other aspects to managing the array that I wasn't aware of. If it's really only when a drive dies that's not too bad. I've been thinking about getting some refurb hardware for home and would love to skip the expensive hardware RAID cards.

Each system depends, you might have blind swap capabilities.

None. Same as hardware RAID. RAID isn't something you touch until you replace drives that have failed.

All enterprise RAID is hot swap. No "business class" software RAID requires you to shut down the server. That's FakeRAID only.

WIth Software RAID and Hardware RAID
In what way? I've always said software RAID is faster and more enterprise, hardware RAID is simpler and more applicable to the SMB.

What are you going to run on it? KVM?

Then yes, MD RAID is built in and will work great. Only thing you lose is blind swap. Other than that, you get a faster, more enterprise system. And as it is for home, you don't have to worry about handing off drive swapping tasks to junior or bench staff.

Or maybe I am confusing Software RAID with FakeRAID...
