I have a Patriot Supersonic Xpress USB 3.0 drive, 128 GB. In a Windows computer, plugged into a USB 3.0 port, it's very fast. On my Retina Mid-2014 13" Base, it's very fast... to start with.
But for some reason, when I open specific files, in particular, 500+ page PDF files from the drive, they run exasperatingly slow. And on the Windows machine they run quick. It's strange. And this happens after about 30 minutes that the drive has been plugged in. If I eject the drive and plug it back in, it's fast again.
This is with any drive I have. Trying to run movies, music, PDF's... A lot of the things I put on my drive BECAUSE they don't require fast speed and run fine even on USB 2.0 speeds... They all have choppiness and color wheel slowdown. Again, this is with ANY drives I have.
The performance starts out quick and then runs painfully slow.
