Yeah i saw some build reviews on freenas, they recommend ecc but it is not mandatory (and actually after reading some tests i don't get all the fuss on ecc ram).
Saw that too and i don't get it, i mean, what the hell? You can replace disks with bigger one but you'll have all this trouble if you want to expand the array? That doesn't feel right.
I'm a developper so i might get into a situation where some zfs expertise might come handy, i spend most of my time (10hours + daily even on weekends) on my computer so no problem.
Thing is spending 600+$$ on a nas doesn't seem worth it compared to buying an high end raid card.
Also it's either having a second case or buying a dual system case which cost more than 500$$, those guys...
Spending much money on a raid card also seem like spending money for nothing too as it seems i'll have better performances with hba card + zfs that using a raid card. (did some research meanwhile)
If only there was a list of compatibility that would solve my problem, i emailed lsi support but didn't get a response yet, the adaptec card seems a bit pricey for what it is.

I choose zfs.
I will probably end up buying a little server since i cannot find compatible hardware cheaper than an full server...http://zfsonlinux.org/faq.html#BasicRequirementsThey recommend 8G RAM minimum, and ECC. Most sites where VM images are used on ZFS recommend SSD for ZIL and L2 ARC to help make up for the IOPS limitation. So don't make the server too little.Also note that growing a pool isn't as easy with ZFS as with either mdadm or LVM. You either have to create a new raid6 vdev (at least 4 drives) to add to the pool, or you have to replace existing drives with larger ones, resilvering between each replacement.I'd do some research before committing to this. It's way more involved than the other suggestions. That doesn't necessarily mean it's a bad idea, just that it'll be a pet needing a lot of attention.Chris Murphy
