I would say no, you'd want the whole disk to fail then so you can just replace it vs. it getting smaller over time, which would make capacity planning pretty complex.

We're talking about RAID1 here, so multiple SSDs. I'm saying you don't want multiple disks to fail in rapid succession, which is what you'd maybe get if you exactly equalized the wear on them.

That makes sense, and you actually do see RAIDs fail like that in the real world sometimes even on non-SSDs.
