Is Riplock something that is initiated by the operating system? I connected my external Blu-Ray drive (Samsung SH-B123L) to the iMac and began backing up Iron Man 2 with Pavtube's Blu-Ray Ripper for Mac. I noticed it was taking a while, so I checked Activity Monitor and noticed the drive was peaking at ~6mb/s. I cancelled the backup, and connected the drive back to my Hackintosh and ran the same process with same programs and movie and this time activity monitor showed a peak of ~12mb/s (twice as fast as on the iMac). I also noticed slow backup speeds when I tried this on my 2011 i7 MBP, but didn't give it much thought at the time. I would think if this was Riplock it would be uniform on all machines (expecially OSX machines), but this seems to indicate that maybe Riplock is something built into OSX? Anyone have any ideas or noticed the same?
