Hi guys, I'm quite curious about the PCIe 4.0x4 for M.2 ssd. I'm planning to buy a Corsair force mp600 and a MSI X470 GAMING PLUS MAX. I see that the Corsair force MP600 SSD Interface is PCIe Gen 4.0 x4 and the motherboard only has PCIe 3.0 and 2.0, do i need to change the motherboard to one which has PCIe Gen 4.0 x4 motherboard or am I understanding the problem wrongly? Thank you.

 

 

 

 

So, PCIe 4.0 is the new standard for Peripheral Component Interconnect express. In order to meet that spec, and thus, get the advertised (loosely) speed, you need all the components in the chain to also support PCIe 4.0 standard. This would include CPU, Motherboard, and SSD. If any of those 3 components only supports PCIe 3.0, then the other components will only work at PCIe 3.0 speeds. So, with your X470 board, it only supports PCIe 3.0 NVMe drives. Spending the higher amount on the PCIe 4.0 SSD would mean you are paying for a feature set that you can't use. Since PCIe 3.0 speeds are plenty fast for a vast majority of users anyways (unless you've got a need for ~5000MB/s), you can either spend less, for the same capacity drive, or spend the same amount for a larger capacity drive.

 

To answer your question in short: Yes, you'd need a new motherboard (X570) to use that SSD. But instead of getting another motherboard, you'd be better off buying a different SSD.

 

NOTE: I don't know if the PCIe 4.0 SSD will run at PCIe 3.0 specs, so worst case: you can't use the drive. Also, you haven't mentioned what CPU you are going with, which will help in directing you to a better option.

 

A whole lotta stuff that got answered before I could post, making this information irrelevant/redundant.

you dont sound like PCIe 4.0 speed will help you. Mind clarifying?

I'm so sorry, but I actually just started on pc building, can you say it in a simpler form?

I believe Jurrunio is asking you about the workload/task you might do, to see whether or not you can take full advantage of the PCIe Gen 4.0 speed.

Thanks Azura Lightfeilt for helping to clarify. I'm actually using that PC to play competitive games, some editing and I'm getting like 2 or 3 monitors.

NVMe SSDs are good for storing footage and stuff while editing so I wont recommend staying on SATA, but in this case PCIe 3.0 x4 drives are enough and there's no need for PCIe 4 drives like the MP600. PCIe 3.0 x4 examples are the HP EX950, Corsair MP510 and WD SN750

 

If you use a PCIe 4.0 drive on this board, it will run at a max speed of PCIe 3.0 x4 bandwidth which means it wont run at its fullest.

pci-e 4.0 is backwards compatible with pci-e 3.0 - anything that can "talk" pci-e 4.0, will work in pci-e 3.0 mode (at its slower speeds).

 

So a M.2 pci-e 4.0 SSD will run perfectly fine in a motherboard that only knows pci-e 3.0, it will simply be limited to pci-e 3.0 speeds ( 4 lanes x max 970 MB/s per lane = 3880 MB/s maximum theoretical)

Since Corsair MP600 is like one of the fastest M.2 SSD on the market, will it the pc crash or spoil easily?
