Second, Sia uses high-scale redundancy which makes the platform substantially more reliable. Probabilistically, a 10-of-30 redundancy scheme is far safer than a 1-of-3 redundancy scheme, provided the reliability of each is higher than 33% (Sia targets 95% reliability for hosts, drives will typically have 98%+ reliability). As the confidence in our software grows, we plan on reducing to as far as a 30-of-50 scheme, which probabilistically is more reliable even than a 1-of-5 redundancy scheme for the same quality of hard-drive, despite being only 1.66x overhead instead of a 5x overhead.
