Thanks, Facej. I’m doing a poor job of asking my question. I don’t expect to beat the internal drive with anything plugged into a port. I’m actually headed the opposite direction - meaning, I don’t want to buy a more efficient EXT drive than I need because fast drives are both larger than I need (more than 128gb) and expensive. Let’s say I want to stream HD video instead of logic library data. I might might automatically feel compelled to buy 180 Mbps based on the false notion that faster is always better. But you might stop me and tell me to save my money because all I need to effectively stream HD video is 5Mbps. This is where I’m going here. I’m wondering if good library performance really requires a fast and subsequently expensive external drive. I’m going to put the library on a usb flash card and check for myself. I don’t expect to break anything trying.
