- M4 Mac Mini - Thunderbolt PCIE Expansion - MacRumors Forums
The 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)
- PCIe SSDs - NVMe AHCI | MacRumors Forums
Note 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
- Fastest Thunderbolt NVMe enclosure speeds - MacRumors Forums
OWC's own page states that the slots are "(4) M 2–2280 “M Key” (PCIe 3 0 x1)" and PCIe gen 3 0 x1 max out at 1GBps The 2600 speeds were because it was in a RAID-0 configuration, but individually it will be limited to 1GBps by the hardware My needs would be to configure it to RAID-1
- MAC PRO 4,1 and 5,1 PCIe AUX Power | MacRumors Forums
The PCIe specifications don't required pin number two to have power, but it also does not prohibit it either In the MAC Pro 4,1 5,1 it is connected To be clear, this delivers the same power as a 8 pin connector without the extra sense and grounding pin on the 8 pin plug Just buy the correct 6 to 8 Pin PCIe AUX cables and you are all set
- PCIe x4 vs x16 for single NVMe SSD speed increase?
With a x16 PCIe switched adapter you are limited to x16 PCIe v2 0 that the switch convert internally to PCIe v3 0 x4, real world ~3200MB s for one blade and ~6200MB s for two or more blades PCIe switched cards start at around US$ 190 for IO Crest IO-PCE2824-TM2 (aka Syba SI-PEX40129), the most used by MP5,1 owners that want high performance is
- PCIE M. 2 NVMe on MacPro - MacRumors Forums
PCIe 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)
- USB 3. x PCIe Cards for Classic Mac Pro - MacRumors Forums
HighPoint RocketU 1244A (untested) PCIe 3 0 x8 switch Each port is provided by a separate ASM3142 With PCIe 3 0, all four ports can do full 10 Gbps simultaneously With PCIe 2 0, 3 ports can do full 10 Gbps simultaneously x8 allows even PCIe 1 0 to do full 10 Gbps HighPoint RocketU 1344A PCIe 3 0 x4 switch Uses two controllers to provide
- PCI-X NVMe raid card. . . | MacRumors Forums
Yes, ASM2812 is PCIe switch but is a PCIe 3 0 switch with only 4 lanes upstream, that is the reason for it to be so cheap Even if is possible that ASM2812 is macOS compatible switch like the big brother ASM2814, no one tested it yet, the card depends on the firmware installed to the PCIe switch to be Mac compatible
