All my disks are 2TB so it shouldn't be a massive issue
I personally wouldn't use raidz1 because it seems too risky to me. I'd have higher redundancy.
Some links

https://magj.github.io/raid-failure/
The last link is talking about actual raid and not zfs. But it has a 50/50 chance with a URE rate of 10^14 to lose the array. Raidz1 maybe won't have that catastrophic of a failure, but you'd still be rolling the dice on some corruption.
