What is the difference between the deduplication algorithms available in QES?

SHA256: A common algorithm which belongs to the NIST SHA-2 family. This was the default algorithm before QES 1.1.3, and is still included for legacy reasons.
SHA512: This algorithm can take advantage of 64-bit architecture. Performance is 50% faster than SHA-256 on 64-bit hardware.
Skein: A high-performance algorithm which belongs to the NIST SHA-3 family. Performance is 80% faster than SHA256. This is the recommended default algorithm.
Important: Before QES version 1.1.3, the default deduplication algorithm in QES was SHA256. If you update a pre-QES 1.1.3 NAS to QES 1.1.3 or later and then change the deduplication algorithm to SHA512 or Skein, data might become inaccessible.
