Hi, Yesterday I bought a Seagate Expansion 3 TB drive as a second off-site backup disk. It's my first USB 3.0 drive, but I'm only getting 50MB/s speeds. Now, I ran BlackMagic's Disk Speed test and here's the weird thing: When my target drive is the HD inside my Macbook I'm getting ~40MB/s seconds, whereas when I select the external drive I'm getting ~130-150MB/s readings. Obviously the bottle-neck is inside the computer, which is really weird. Can anyone help me out here? Thanks a ton.
