There was a problem hiding this comment.
For some more context, the approach I had in an earlier iteration of this was that I pre-allocated a single array that would hold the contents read by the diskarray. Then you could readblock! directly into that array allowing us to get away with minimal allocations.
However, this approach seemed to be slower than even the current approach, not sure why.
