OK - so they do a block level checksum (no error correction but it would let you know that something went wrong). Now something goes wrong with checksum. Is this a "zero cost" feature to have every app updated to handle this checksum error. What is gained? If you need reliability do something like SSD or a raid option and a backup.
- wang_li 7y agoThe apps don't have to deal with it. It's a read error. Presumably something they already deal with. There's no operational difference for the end user between a block that can't be read and a block than can be read but with corrupted data. And yes, storage would ideally be paired with another physical device to provide redundancy and a mechanism to correct the error on the erroring device.
- zeotroph 7y agoOr just pair it with iCloud and "cloud heal" the corrupted local data. Then mark the sector as bad and enjoy longer lifetime for the device.
