2024年11月15日 · 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).

2018年10月9日 · 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.

2018年5月14日 · Apple (Mac Mini) uses a PCIe 2.0 connection with a x2 link width, giving a total of 5 GT/s. PCIe 2.0 1x can handle 5 GT/s, and in System Information, the link speed is 5 GT/s. Since PCIe 2.0 requires 10 bits to encode 8 bits of data, 5 GT/s converted to Gbps (gigabits) would be 5*(8/10) = 6.25 Gbps. Divide by 8 to get GB/s = 0.78125 GB/s.

2012年4月20日 · SABRENT M.2 SSD NVMe to PCIe Adapter with Aluminum Heatsink and Thermal Pad, for SSDs up to 16TB, M.2 NVMe to PCI-E converter 3.0 X4 X8 X16 Card (EC-PCIE) At least Sabrent is an established brand. Likewise I put a Samsung 970 EVO Plus in it, also recommended by bookemdano above, and I think widely recommended elsewhere.

2020年10月6日 · The Samsung NVME Phönix controller APFS problem might be solved with Sequoia but i cannot confirm and the 990 is maybe not affected because of a different Controller and at least the Samsung NVME used with PCIe Card and Raid where showing up again in MacPro 7,1 after Sequoia update. So there is hope HFS+ is working anyway.

2017年2月2日 · 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).

2005年10月31日 · I have a moderately updated 5,1 Mac Pro - currently with a generic USB3 PCI-e card providing four additional fast USB ports. I now need to connect a USB-C device to the machine. I am not sure whether it is better to use a USB-A to USB-C converter plug or to add an additional (or replacement)...

2012年12月3日 · 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 ...

2014年7月12日 · The 7800GS AGP and 7800 GTX 512 PCIE were done by myself. I seem to recall that the 7800GS can run a 30". Most 6800 cards can NOT, but the Quadro version can, if you change the device id in the rom. Had a lot of fun …

6 天之前 · Considering a 1tb PCIe card, for a 2014 MBA Have read the the 2015 MBA & MBP use 4x PCIe storage, while earlier models used 2x. Question #1 can the 4x be used in a 2014 but perhaps run at a slower speed If so, might as well just look for 2x PCIe: Question #2 Apple 1TB SSD SSUBX is 4x? Apple...
