File system for nas?

[bobhays]

Hi everyone I'm planning on building a small home nas and before I decide what os and parts to build I need to decide what file system I want the nas to run.

 

I know that as storage drives and files get bigger and bigger bit rot/data rot becomes more and more of a pressing issue.

 

Other than ZFS (which I would use FreeNAS for), are there any other ways to prevent bit rot?

I heard of ReFS for windows which also does checksumming to prevent bit rot. Is this a viable option (windows 8 pc with shared pools?)

 

Are there any other options that I don't know of or a way to scrub and NTFS drive?

 

Thanks for the help.

Hey there bobhays,

 

Bit Rotting is a known issue that neither RAID nor backups will help unless checked manually. Although you are not particularly likely to suffer from this, you may have to deal with this problem if you are using older drives or keep files for a longer period of time without refreshing them. I believe this article can give you some useful info: http://arstechnica.com/information-technology/2014/01/bitrot-and-atomic-cows-inside-next-gen-filesystems/

 

Using NAS/RAID-class drives in the NAS should lower the chance of suffering from bit rotting.

I am looking into using ZFS/BTRFS/ReFS to help prevent bit rot by using check sum. If I do decide on ZFS I will go with freeNAS but would it be possible to use ReFS (windows supports it). I'd use ECC ram since that's will improve the protection. The reason I'm looking into ReFS is so that I don't have to buy as much RAM as required by FreeNAS and so that I can use a cheaper AMD processor.
