I wasn't talking about the disk buffer. The OS buffer is only a few 10's of Mb in size at most. I don't know why you think there is no limit to its size. Buffers are allocated out of the OS memory pool. Its not possible to have 50Gb of I/O ops waiting to be written out. That would exceed the total physical memory on the Server. Robocopy chokes on large files (i.e. over 10 GB) because of how it does copy operations (buffered vs. non-buffered I/O), and since we have some rather large files (videos, exchange, etc.), robocopy doesn't work. Although I sure tried to make it work. And learning about diskshadow commands to create your own VSS copies was fun.

Given the 2 functions below one for calculating the md5 of a given file and one for copying a given file, I want to merge the two functions so that in a single read (pass) of the source file the file is copied and checksum'd at the same time reducing the disk I/O by half, the reason for merge of the two functions is I am copying 200gb+ of data

I was looking at the actual syscalls that robocopy makes and one of them is to NtQueryVolumeInformationFile to see if either path is a remote, UNC or not. If so, then it disables local file buffering and it also uses different I/O buffer size.

Later versions include multi-threading and un-buffered I/O support. Important. Robocopy does not copy exclusively locked files. If users tend to lock many files for long periods on your file servers, consider using a different preseeding method.
