Did a fresh dd test just to confirm, same results:
[root at cpu_crew1 benchmark]# dd if=/dev/zero of=/shared/working/benchmark/test.cpucrew1 bs=512k count=10000
10000+0 records in
10000+0 records out
5242880000 bytes (5.2 GB) copied, 7.43695 seconds, 705 MB/s
[root at cpu_crew1 benchmark]# dd if=/shared/working/benchmark/test.cpucrew1 of=/dev/null
552126+0 records in
552125+0 records out
282688000 bytes (283 MB) copied, 37.8514 seconds, 7.5 MB/s

And the 70-80 is sequential, not random for reads, same exact test commands on the disk server are in the 2+GB/s range, so I know the disk server can do it.

If you are going to have many files with a wide variety of sizes glusterfs/fuse might not be what you are looking for.
