- rbanffy 8y agoDuplication halves the write speed (and only tell you the data is bad, at half the read speed). ECC would reduce RW speed somewhat still, but, at least, would allow one to correct the data and rewrite it.
- fooker 8y agoDuplication does not have to be online, especially if speed is a concern.
- eximius 8y agoDuplication is a form of ECC (admittedly a bad one). If I write everything 3 times, I can correct from any single error, but I will erroneously correct on two errors. If you're limited to duplication, you'd want four copies for 1 error correction and 2 error detection.
- rbanffy 8y ago> 3 times That would be triplication. ;-) Duplication is only single error detection.
