Other thoughts: A 2-of-3 secret sharing scheme can guarantee that a breach of any single server would not result in any information being revealed, and the destruction of any single server would not result in any information loss. A more costly 6-of-8 scheme can guarantee that 5 servers can be breached without information revealed and 2 servers can be destroyed without information loss. The more servers the data is spread between, the greater the guarantees of privacy and redundancy become. Space usage is similar but worse than error correcting codes. 10 1TB shares can store 7TB of secrets while tolerating two failures. 10 1TB drives in RAID can store 7TB of data while tolerating 3 failures. Latency is not multiplied but you get the worse case more often.
