MTBF of samsung flash parts is allegedly around 1.5Mh. That's one in 171 years. A battery, on the other hand, is (almost) guaranteed to need replacement after ~2000 cycles, or 32kh. That's a difference of 46x.

SSDs fail not because of their NAND reaching MTBF. That would be the perfect world if that was the only variable.

  This is MTBF of the entire drive (I used a Samsung 980 MTBF for reference). I think it's pretty clear that, barring accidental damage, the battery is by far the most likely failure point on macbooks.

    It is, but I've seen enough laptops go back to the IT department due to SSDs randomly dying on them way before their batteries died or them reaching their claimed MTBF which mostly applies to laboratory controlled conditions, not real world usage. Same with my old corporate HP. SSD (SK Hynix) died within one year.

      That's the point of the M in MTBF: it's a mean. Some drives underperform, others overperform. One sampling from Backblaze shows this MTBF to be (roughly) accurate: https://www.backblaze.com/blog/ssd-edition-2022-drive-stats-review/ https://www.backblaze.com/blog/ssd-edition-2022-drive-stats-...
