I'm looking to add a Samsung 950 nvme to my iMac and wanted to know how to go about setting this up? I know there's PCI-e to thunderbolt 2 expansion devices out there, but I'm wondering: 1. Which is the best option to take full advantage of the Samsung 950 (or similar SSDs with 4x pci lanes?) 2. How will the speeds through the thunderbolt compare to internal PCIe setup? Also in terms of IOPS and latency? 3. For people who do use PCIE to thunderbolt external adapters, what other devices do you use it with (video cards, etc) Edit: Also, if anyone knows a good SATA to Thunderbolt 2 enclosure, please let me know!
