...stination needed.
My ultimate would be something like:
while (files) {
while (data_in_file) {
read user_defined_blocksize to ram from file
write user_defined_blocksize from ram to file
}
fsync() ensure 1.5 GB file is on disk
} endwhile
Thanks

...ent source media, but the same destination (It's a faster drive
than the source media).
I got 120 MB/sec write speeds to the destination in that mode. Both

I moved it to a linux box and the behavior is much better. I get a
nice smooth 85-90 MB/sec. That might be the max speed of the source
drive.
I'd still like a way to improve rsync's performance in cygwin, but I
can understand it is a low priority.
Thanks
