View Full Version : Very slow copy speed to external drive

12-07-2012, 11:45 PM
I have a Voyager enclosure attached to my Mac Pro via eSata, with a WD 2 TB drive in it right now. I'm copying about 500 GB of media from one of the internal drives to the Voyager using SuperDuper, and I'm seeing a copy speed of 4 MB/s, which is incredibly slow. That's not right; eSata should be 40 MB/s at a bare minimum. Any idea what could cause a slow down like this?

Bad cable, connection, case, slow drive (source or destination), other applications interfering with copying (AntiVirus, etc), Spotlight?
