- Piskvorrr 8y agoThey're capable of pushing down the odds, at a price.
- zaarn 8y agoWith some probability, yes, but it's still non-zero. There are other failures where ECC doesn't help (ie, bitrot on your SSD or Harddrive, cosmic ray hitting the CPU itself, anything that does DMA). The best we can do is deploy ECC, hope the cosmic rays don't hit our Datacenter too hard and design software to fail fast if it fails, even if math says it can't fail. Because it will fail.
