- M4 Mac Mini - Thunderbolt PCIE Expansion - MacRumors ForumsThe Express 4m2 configures (by hardware or firmware) the PCIe switch of the Thunderbolt controller into four x1 slots. The Accelsior 4m2 has a PCIe switch to convert an x8 slot to four x4 slots. The Accelsior 4m2 is going to be more expensive because of the extra PCIe switch (plus the larger Helios Thunderbolt enclosure).
- Upgrading 2013-2015 Macbook Pro SSD to M.2 NVMeThe 2013-2014 15" MacBook Pro originally shipped with 2x lanes PCIe 2.0 AHCI SSUAX SSD (speed ~700MB/s). They all support NVMe SSDs at full 4x lanes PCIe 2.0 speed (~1.4GB/s) with no size limit. The 2015 15" MacBook Pro originally shipped with 4x lanes PCIe 2.0 AHCI SSUBX SSD (speed ~1.4GB/s).
- PCIe SSDs - NVMe & AHCI - MacRumors ForumsNote that PCIe SSDs installed in a Mac Pro 5,1 (MP6,1 have exactly the same PCIe 2.0 limits too) are limited to ~1,500 MB/s unless installed on a PCIe switch card in slot 1 or 2 such as a HighPoint SSD7101A-1 or Amfeltec Squid that converts the Mac Pro PCIe 2.0 x16 to the PCIe 3.0 x4 needed for full throughput.
- PCIE M.2 NVMe on MacPro - MacRumors ForumsPCIe SSD may help on loading very large apps with huge library. But in general (I mean loading apps, but not copying large file etc.), should makes very little difference. Anyway, this is a video to show the apps loading time on my cMP with the 840 Evo just plug in the optical bay (SATA II connection).
