Oh, interesting. I was inferring that from the Go code out there that uses machine code directly: https://github.com/minio/blake2b-simd/blob/master/compressAv...
I guess it must be a recent addition.

What Hacker News says
4 sourcesYes true. OpenSSL version gives a great boost. Rather than SHA512 we ended up using Blake2b - https://github.com/minio/blake2b-simd (also optimized with SIMD instructions) internally for bit-rot verification in https://github.com/minio/minio
In Show HN: Accelerating SHA256 by 100x in Golang on ARMHello HN,
Here is a bit more explanation about erasure code and bit-rot protection.
Minio along with being S3 compatible also protects data against hardware failures and silent data corruption using erasure code and checksums. You may lose roughly half the number ((N/2)-1) of drives and still be able to recover the data.
Minio uses Reed-Solomon code to stripe objects into N/2 data and N/2 parity blocks. This means that in a 12 drive setup, an object is striped across as 6 data and 6 parity blocks. You can lose as many as 5 drives (be it parity or data) and still reconstruct the data reliably from the remaining drives.
Minio also supports bit-rot detection transparently which works along with erasure code using high speed BLAKE2 - https://github.com/minio/blake2b-simd hash based checksums.
