Correct me if I'm wrong here, but I remember that SSDs lifespan mainly depends on how much you overwrite the drive. For 128TB, it should take you a very long time to overwrite the entire drive, let alone couple hundred or thousand times to kill the drive. I know that bit rot also happens on SSDs, but that applies to HDDs as well, and good drive maintenance practices should alleviate the issue. Though for archival purposes/cold storage, tape drives are probably better.

The lifespan of your data isn't nearly as long as the lifespan of the cells storing your data. Due to leakage of of power from the cells, and the more and more dense these cells are being packed (leading to smaller differences between what voltage maps to what binary value), SSDs have issues with bitrot. With a disk this size you would need to have data regularly checked and refreshed (rewritten) to ensure the data being stored was still correct and not corrupted.

All storage has issues with bit rot. There haven't been any studies to show that SSD is disproportionately affected.

In 2016, HDDs were more reliable (MTBF).

In 2022, for the first 5 years, SSDs are looking more reliable. With more of a constant failure rate (1%/yr), than the increasing failure rate of HDDs after 5 years.

(Caveat: not just bit rot, but general failure data.)

There's a caveat there. We've had some new tech in SSDs come out very recently, new enough not to be in those charts will still have to see.
