You never explicitly say what's the whole idea, what are you protecting against. By mentions of bitrot and of dm-integrity, you seem to think that when hardware is "starting to fall apart" the disks will eventually start returning wrong/corrupt data. Thing is, they do not. What you will get on disks going bad is uncorrectable read errors (UNC), not a silent corruption. The latter is still possible, but more likely to be caused by the SATA controller issues (or its driver/firmware), not disks. And those are hardly related to whether it's "new" or "old". -- With respect, Roman
