My copy speeds are half the rate when I copy to the same HDD (same partition) compared to copying to a different physical drive. All partitions in my comparison are formatted with the same large cluster size and I am copying the same large files (8Gb vmware disks.) I use SuperCopier2 to copy.
Same disk average 30Mb/s
Different disk average 60Mb/s
Also, my normal USB 3.0 transfers for large files average 50-60Mb/s.
What gives?
