Will m.2 eat up my pci-e slot

[TrYeX]

If i put a m.2 ssd in my msi z270i will it eat up my pci-e slot ,so my graphic card will collaps due to being bullied by me for being slow.

m.2 is a different connector, it uses electronical pci-e lanes not the actual connector.

No. For one NVME uses the chipset's PCIe lanes, not the CPU's where the graphics cards go to. For another, using NVMe may instead disable two SATA ports.

NVMe usually disables a PCIe slot, either an x1, x2, or x4, or eSATA ports.

Ahaa i get it m.2s only eat satas, thanks!

No they don't. they disable U.2 usually. SATA doesn't use PCI-e

I think it's different on every board model.

 

And SATA does use PCI-e.

SATA Express does, but not SATA III (normal SATA)

if it did, then why would it be capped at 6Gbps

[knightslugger]

Both SATA and SATA Express use PCIe Lanes, just like USB, just like thunderbolt, just like HDAudio... Just like every single I/O on the MB.

 

It's a matter of HOW MANY.

 

Not sure if i should really dig into why some I/O is capped at certain speeds and why others aren't...

motherboard manual will tell you which ports are shared with m.2.

The 100 series PCH contains 20 PCIe 3.0 lanes to use for connecting peripherals. How these lanes are used are up to the motherboard manufacturer. In this case, there are three NVMe capable drives, and using them would disable all of the SATA ports and three of the GbE ports, because it has to use one or the other.

whats funny most professional reviews dont mention what ports are shared or disabled.  This is important part of the buying processes now since we have limited sata and PCIE lanes

[brighttail]

Bottom line it depends on your motherboard.  Different motherboards treat m.2s differently.  I've seen some say you can only use an m.2 or U.2, not both. Others will take the lanes from a Sata or Sata-express ports and other still will actually disable a Pci-e slot, all depending of course if you use the actual m.2 slot or a PCI-e slot.

 

I suggest you check your manual.
