I stored 2tb of actively used data on zfs without ecc ram from freebsd 8 to 12. I had no noticeable corruption. I only post this because there is a weird assumption that not using ecc ram is a death sentence for your zfs data.
I use ecc ram now and I think it's the proper way to do zfs, but let's not pretend you forfeit your data by not using ecc.
- vermaden 5y agoECC RAM is useful for ALL FILESYSTEMS - not just only for ZFS. But from all filesystems ZFS works best of all when you do not have ECC RAM. The 'requirement' that ZFS needs ECC RAM to work properly is one of the biggest myths of the Internet ...
- dangerface 5y agoI am happy that worked for you but there is a huge difference between a 24 x 4tb pool and a single 2tb drive. 2tb is not a lot of data you would need to fill the drive 4 times a day before you would get close to hitting the single bit error rate, a pool of my size is guaranteed to hit that error rate just because of the volume of data. If we are talking about running zfs on a desktop then yea you are right you don't need ECC, but if you are running a storage server for data you want to keep then you absolutely do.
