I've recently installed a SSD to work as a dedicated cache drive, and I've directed the 3 cache settings in AE (CS6) to it.
The drive is 240GB, but I can't put the cache size over 150GB without getting a warning that it's set too high. Is this true? Am I wasting almost 100GB?
Use your drive for something else. 150GB is a huge huge cache. The CS6 disk cache is glitchy anyway. I have mine turned off most of the time.
