Thank you, Simon. Fascinating and helpful. I think yours is the first-ever mention of advice where to store the generated tracks for best speed.

My empirical experience, with absolutely no scientific tests, is that starting and using the program feels ‘snappier’ if it’s on an SSD. But generating songs works remarkably the same on my two computers, one of which has the RealTracks on a 10k internal hard drive and the other on the supplied PG Music external drive. On both computers, the program loads from an internal SSD, so the only difference is the location of the RealTracks. Note: audiophile version on both.

Simon, would you consider writing a post for Tips and Tricks? Perhaps something like, What speeds up BIAB, and what doesn’t?
