  FW800 is up to 80-95 MB/s fr 60 MB/s after clean install w/ OSX 10.9.1

  For some miraculous reasons, FW800 ext. enclosures are getting a 20-35 MB/s increase in read speed in 10.9.1. It’s actually in par w/ USB3 on the MBP Retina when it comes to read speed. On the exact same Mac Pro, when I boot in OSX 10.6.8, speed dropped to 60 MB/s. So there’s still life left for those expensive FW800 enclosures.

  I’m performing massive LTO-6 tape archives directly from these FW800 drives and read speed increase saves 2-4 hours of the total backup process.

  I assume you simply moved them over and didn’t reformat the drives?

  Correct. On the Mac Pro hdd bay 1, there’re 4 separate OSX partitions fr. 10.6.8 -> 10.9.1. All of those years FW800 bandwidth was limited by the OSX. Data was fixed and no reformat done. I was archiving to LTO-6. Didn’t have a chance to benchmark 10.7 -> 10.9.1. This was a clean install because of FCP 10.1 performance.
