You're spending weeks of time reinventing wheels so chasing a wee bit of
disk io speed doesn't compute.  Also using the 9 branch flies in the face
of your stated desires.

A single SATA is going to do about 1GB in 10 seconds which is an order of
magnitude more what a 1Gb NIC would allow to transfer.
