I wouldn’t bother getting an external drive for storing music on if you laptop hard drive isn’t overflowing – I keep all my music on my hard drive – which is a SATA 1 500GB disc in my now getting-on-a-bit Dell laptop – and I have no problems loading tracks in VDJ. You would find that the track loading time would be increased using an external disc – any drive not attached directly through SATA will be slower than a SATA disc..
A prime example would be that I have a version of windows 8.1 installed on an external drive (USB 3.0, 300Mb/s drive) as a backup – and that takes over twice as long to boot as windows 8.1 does from my hard drive.
When you say it stutters, do you mean that the audio output stutters when you try to load a track? If it does, try increasing the latency on your soundcard – I had that problem (I was running mine at 3ms though lol) and that fixed it.
