Want to get a 2014 Mac Mini for use wth LR and my twin Apple 27" LCD monitors. I am caught between what would be the best option for it, my indecision is on the drive setups, I will be getting 16GB of ram and the 3.0 GHz i7. Should I: 1. Get the 1TB fusion drive, and replace the 1TB HDD with a (spare) 1TB SSD, but as a separate drive. Will the internal 128GB SSD be enough for running the system, LR (Classic CC) and occasionally PS with the system files comfortable? I will put the LR preview cache files (somewhere around 250GB) on the 1TB SSD, the actual photo files, 1.5TB, will be on an external USB3 drive. LR is much faster with the preview cache files on the SSD. Currently the cache files are on the same 1TB SSD as the system files and I am very happy with its performance. 2. Get the 256GB SSD option. I would set the system, preview cache and photo files the same as option #1. I am not quite sure if the most current Mac Mini SSD blade only model comes with a cable to allow me to add the 1TB SSD as a 2nd internal drive. This option gives me a bit more room for the system files, but may I have to get a cable. Both option 1 & 2 are the same price. 3. Get the 512GB SSD. Same situation as #2, just a bit more system breathing room and I should easily be able to put the system and LR cache files on the 512GB blade. I would most likely put a 2TB HHD internal drive in the 2nd drive slot and not have to deal with the external USB drive (except for backup) for my photo files, which I like. The difference is $150. Don't really want to spend for option #3 unless the 256GB option 1 & 2 will detract in LR performance. Same for the 1TB blade option, $300 more. I have a really great 2012 MacPro hex core that I use for heavy lifting in PS and LR, it's just that it is a heat generator in the summer months and since I live in the desert, I am constantly running the AC in the house to cool down the room I am in. What pros and cons can you LR users suggest?
