Well no, I have thought of exactly that scenario because that is exactly the scenario I'm currently in running a Pentium D SL88T with 4GB non-ECC on a 1TB RAID1, but I know not to come crying to the forum when my pool randomly self-destructs because of the current hardware situation not meeting minimum requirements........
So do I, so whats the point
............and I know to make sure to keep proper backups that never touch the NAS for just such an eventuality..........
So do I , so why are we discussing this?
..........and I know to really only use it for testing purposes until that point in time anyhow when I can save up for my planned build
You said you know to only use it for backup purposes but then eluded to the fact you keep actual personal data on it and do popper backups. Sounds like a contradiction but so what. What does it matter and what is the point. I mentioned just the same thing earlier that if your backing up your data, so flipping what if you have a bitflip or your RAID explodes, implodes or goes through a worm whole into another universe. You rebuild it off of your backup data. Why would you have to complain to anyone on the forum or not? I think too many maybe even the 'Experienced People' are implementing ONE RAID for their data without backup and hopping to design so much redundancy and fail-safe so that it they could only loose their RAID if all the planets align perfectly and they were standing on one leg, hopping counter clockwise with their tung sticking out to the right...... which COULD happen. Well if they are dong this and don't have a secondary backup I would sure hope that ECC of paramount importance to them.
I lament to a previous poster ............................
Richman,
To me, ZFS or RAID is not backup. I have a separate backup storage and so should everyone. As such I don't consider ECC memory to be all that important and use consumer based hardware on the FreeNAS systems I have. To me it is no different than a motherboard or cpu failing, or even a fire or flood at home. I can't protect against everything and I can only do risk mitigation, if so I choose.
With that said, I plan to upgrade to a mini itx server board in the distant future.
I am playing devils advocate hear, not that I am going to do this myself. Havn't actually made any definite plans.
What is wrong with the statement by engmsf. We are not talking about all the numb-skulls that never hardly read a thing and when they have issues come crying to the forum. Were talking in general.
We are not talking about data of a financial institution, or hostpital, CIA, NSA, corporate data or irreplaceable data of any sort on a server that just always needs to be up and as little corrupted as possible. Knowltey may say your better off going with OpenMediaVualt. That is personal opinion and I may even actually do that, who knows.
If you're just temporarily using the sub-requisite hardware to test and get yourself familiar with FreeNAS before making an actual investment than that is perfectly fine and expected, but if that's the case then why are you throwing up such a stink about the ECC requirements if you're already planning that route as it is?
What does it matter if you are using sub-requisite hardware for testing or real world if you have everything backed up?
Who is throwing up a stink about ECC? Who......me?

I think ECC is great to have and I think I only mentioned it on page 2 until now. The OP questioned it and I took his question further. Sometimes I may play devils advocate.
But for the people that are just simply wanting a server solution for their home so that htey can access their data from their desktops as well as all their laptops, TV, smartphones, tablets, etcetera, but really don't care enough about the data in questions protection to buy hardware specifically designed for that purpose, then it makes me wonder why they are looking into software and a filesystem specifically tailored for that purpose.
No need to wonder too much or loose sleep over it as I already explained the why. But to expound on the why to make it more specific and tailored to your question I will say:
1. FreeNAS is compelling in light of its feature set
2. Doesn't make sense to switch platforms after hardware upgrade if you are planning on implementing ECC at some point. I see the benefit of ECC even for personal home use even though that benefit isn't as large as it is for a corporate or business environment.
3. I'm a geek and like to play with things, even in the enterprise geekdom arena
4. I like the community and development team as I checked out several.
5. I wasn't specifically looking for a 'file system specifically tailored for that purpose' originally. I was looking into RAID and NAS about a year ago and stumbled on ZFS via that route.
6. For web server file storage ....... later in the works.
7. I could get better performance for media files but since I am gong to have more than one RAID array, I don't see the reason to have two boxes. I feel they can perfectly reside in one box and kill two birsd with one stone as FreeNAS will handle that.
Basically if you're just using consumer grade hardware temporarily while you save up for the kind of hardware that complements the OS and filesystem you are using with FreeNAS then you're the person buying the truck in anticipation for that farmland you're savins up to purchase later in the year. But if you're just using FreeNAS because it's the first NAS solution you came across in Google, or found about from any of the various life hack articles that are likely old and actually referring to the software that is now known as NAS4Free but don't really care all too much about the safety and integrity of your data then FreeNAS is probably just a little overkill for you,.....
It wasn't the first NAS solution I came accross, ..... more like the last or second to last.
Overkill? I don't care, I love overkill and sometimes I go overboard in overkilling the overkill.
Find me ANY motherboard under 50 dollars that isn't absolute shit. Server board or not a motherboard under 50 dollars is going to be shit. You don't find server boards under 50 as much because the server board manufacturers know this and don't waste their time with that market segment since people looking for server hardware are going to also be looking for quality hardware, it sort of th entire point of them looking at server hardware.
I found a two used boards that were almost like new for around $30 that had Atheros LAN, and the other had dual Intel LAN and they were not the junk end of the consumer line. If I could find a used server board for double that I would consider going that route immediately.
If you really want to get into the territory of unreasonably priced hardware get into "medical grade" computer hardware where a 4:3 1280*1024 greyscale computer monitor can be yours for a smooth $12K
Don't get me started on the medical field. Course, if I was a Dr. I would be paying someone to build my NAS and this conversation wouldn't be happening.
