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.
