"As you said there are cases where putting the library and cache files on an SSD (even the system SSD) can help performance. However it can be difficult to determine whether this helps. Just because your spinning RAID array is chugging loudly doesn't mean it's overloaded. Lots of people speculatively put items on SSD, yet it may not help performance if the workflow isn't I/O-limited. If you measure the before/after timing of a specific workload and it's faster with library on an SSD, then that's good evidence but methodically doing such things is time consuming."

Tests like this are indeed time consuming, but so is waiting say 8 hours for waveforms to draw when the Library is on a RAID vs on the internal SSD, which is at times twice as fast. After a few years of cutting one recurring type of project with the Library on a RAID, then cutting the same project with the Library on the internal SSD, and seeing dramatic differences, the results were actually not difficult to determine at all —just move the Library to an SSD and compare the times. Granted, some of this speed improvement is moving to a beefier machine, but I tested the iMac Pro with the Library on a RAID and on the internal SSD and there is a huge gap in the amount of time it takes to draw waveforms.
