Just wondering if it is better to get the nMP with only 256GB SSD (for the OS, apps) and hook it to a Promise Pegasus2 TB array, which can deliver data faster than the internal SSD, versus upgrading the internal SSD to 1TB? I have on order an nMP with 1TB SSD, but I am wondering about changing it. What do you guys think? (My usage is Lightroom and FCPX and I am ordering a 6c model with D500) ps: Would LR5 benefit significantly if I went to 32GB RAM or is 16GB plenty if I am not running other apps at the same time? My MBP with 16GB ram doesn't seem to use much ram with LR.
