So I built a zfs raid nas box with 6x3Tb drives. I have it resilver every 2 weeks. So far, NOTHING has failed checksums for almost 2 years. So while the maths behind a 3-4 tb drive returning incorrect data I'm sure is technically correct, I've not seen issues.
If you want "proof" i can dump out zpool status/info/log/etc to show i'm not lying. Note the pool is ~50% in use so its not a great example. Also its raidz2 (raid6) so not a direct comparison. I also bought each drive from different lots to hopefully ensure if a drive failed i'd have 2ish days to get a replacement.
