"Does the SSD iMac have an SATA connector?"に関する回答I agree with Dan When I upgraded my iMac 2015 27" 5K, I tried all the possible ways. I replaced the original 3.5 hard drive to Samsung 850 Pro SSD 500GB, installed an external enclosure thunderbolt with same Samsung 850 pro SSD 500GB. And finally installed a PCIe blade SSD.

Using Black Magic: (1) Original HD was 100 MB/s (2) Updated the internal HD to Samsung Pro 850 SSD was 350-400 MB/s (3) External enclosure with Samsung Pro 850 SSD was 300-400 MB/s (4) PCIe blade SSD was 600-700 MB/s As you can see the enclosure with SSD has only minor difference. but you don't have to open your brand new iMac and having the warranty void.
