The second is that I've heard a lot of anecdotal evidence that an SSD for the primary drive, and for the lightroom catalog will make a big difference in performance. The one person I was able to find who benchmarked this found no difference in performance: http://www.computer-darkroom.com/blog/will-an-ssd-improve-adobe-lightroom-performance/
first, those were clearly compute-bound tests, so the SSD didn't really get tested; because of that it doesn't matter that he put the SSD on the slower of the two internal buses on the MacBook Pro in question, though it would have made a difference on i/o bound tests
further, that's four years old — even if your Mac is that old, Lightroom and SSDs have both changed significantly since then
Has anyone done any actual benchmarking on this?
not me
SSDs do give a benefit in latency, but do they have any higher of a data transfer speed? What about PCI-Express SSD cards? Are they any better than SATA SSDs?
today's SSDs almost always outperform spinny disks in transfer rate, and SATA can be the limiting factor on fast SSDs; external buses like Firewire, USB-3 or even Thunderbolt 2 can also be a limiting factor
what i think you need to find out is whether i/o speed is important to your workflow; i understand LR6 has *some* optimizations to use GPUs on Macs now, and likes quad i7 CPUs; and i would expect maxing RAM would be important too; after addressing those, as the processing part gets more efficient, the relative importance of file system performance will increase
