Comment on ZFS: Should I use NAS or Enterprise/Datacenter SSDs?
Pete90@feddit.de 1 year agoI barely scratched the surface with ZFS, so I’m not going to touch another file system for a while now. I’m fine with detecting data corruption only, since those files (on the static data storage) can be replaced easily and hold no real value for me. All other data will be either on the redundant pool or is saved to several other media and even one off-site copy.
I already wrote down ashift=12 in my notes for when I set it up.
In general, I found there is a lot of FUD out there when it comes to data security. One I liked a lot was ECC RAM being mandatory for ZFS. Then one of the creators of it basically said: "Nah, it’s not needed more than for any other file system’.

Yeah ECC RAM is great in general but there’s nothing about ZFS that likes ECC more than any other thing you do on your computer. You are not totally safe from bit flips unless every machine in the transaction has ECC RAM. Your workstation could flip a bit on a file as it’s sending it to your ZFS pool, and your ECC’d ZFS pool will hold that bit flip as gospel.
