I'm not using tapes through, I'm using ssds, flash drives, and hdds. I'm sure they have some internal ecc, but is it enough?

- dmitrybrant 5y agoCorrect, all modern storage media perform plenty of internal ECC. That's basically what "bad sectors" means: the drive wasn't able to correct the data on that sector using ECC. The drive will never return the actual "raw" data -- it's either valid data or a bad sector. This means that if you want to add your own application-level ECC, it would need to be enough to correct an entire sector's worth of missing data. For most applications this would be a prohibitive amount of extra overhead.
