- 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
- When Will Apple Silicon Support PCIe 5? | MacRumors Forums
PCIe is only used for WLAN and Bluetooth and Thunderbolt Looking at the ioreg of an M1 MacBook Air, the PCIe root port for WLAN and Bluetooth devices says it's capable of 16 GT s x1 (PCIe 4 0) but the status says it's running at only 2 5 GT s x1 (PCIe 1 0) which is strange because the devices (wlan and bluetooth) that are attached to the root port have capability and status of 5 0 GT s x1
- PCI Express Terminology | MacRumors Forums
The M2 Ultra Mac Pro has four PCIe 4 0 x8 and two PCIe 4 0 x16 slots That adds up to 64 lanes vs the 24 lanes available The M2 Ultra talks to the expansion slots via a PCIe switch chip that routes those lanes as needed based on what cards are actually in use, similar to how a network or HDMI switch operates
- Mac mini M4 Pro Dock — Thoughts on Beelink’s new Mate mini?
Model A: dual PCIe SSD slots, up to 16TB; Model B: single PCIe x4 slot, with read speeds up to 6228MB s; Specs look solid, and the design seems pretty clean Anyone here ever used Beelink products before? Wondering how their build quality and performance stack up Might grab one when it’s available, but would love to hear your thoughts first
- Intel 750 nvme pcie SSD on the G4 G5? - MacRumors Forums
The Samsung SM951 (PCIe 3 0 ×4) has been shown to hit 800 MB s in the Quad (PCIe 1 0 ×4), but it can do much more via PCIe 2 0 or 3 0 Attempts to raise that limit can be made using the SM951 I suppose, although an NVMe driver for OS X on PPC would definitely be cool
- PCIe card to upgrade all internal HD bays (Mac Pro 5. 1)
At the moment, I'm using 2 Syba PCIe RAID cards (due to 2x PCIe speed capping data transfer at around 700MB s) to run 4 SSDs in a RAID 0 The 4 SSDs are arranged and held together with foil tape to fit the space of 1 internal bay (Bay 4) I use another SSD for Windows in Bay 3 via an Icy Dock
- 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
