I’m buying a new computer, and I’m really struggling whether to dish out $400 more for a 1TB SSD (instead of just 512). For context, I’m buying a 13” MacBook Pro (8th generation quad core intel i7 processor, 16GB 2133MHz LPDDR3 RAM). At the moment, I’m using about 220 GB on my old Mac. 30 of that is my LRCC library, 25 is my LR Classic Catalog. At the moment, that leaves a healthy half the drive open. Original images are stored on an external SSD. The question becomes, how tight can I get before it starts to impact cache performance? What should I have free for Lightroom CC and Classic to operate most efficiently?
