Z390-e M.2

[Nahiko]

Hi LTT,

I'm new here and wanted to ask about installing a second M.2. I currently have a Strix Z390-E board with a Samsung 970 EVO Plus Nvme installed in the bottom M.2 Slot (below the GPU). The boards manual doesn't really offer much detail about the second slot and i don't really understand M.2 form factor that well so i am confused about 2242-2280 and 2242-22110. 
Essentially i am asking if i can install the "Intel 660p Series M.2 NVMe SSD 2TB" in the top M.2 slot without any drawbacks. I intend to use the 2TB as a place to store my steam library

More details about my current build:

Intel 9700k
RTX 2070 Super
Strix z390-E board

Samsung 970 Evo Plus 500gb (boot)
8TB seagate Ironwolf HDD (Archive)

Any assistance is greatly appreciated!

you should be good, the different numbers you're confused about are different form factors for m.2 drives

 

If I remember right the 970 evo is technically using 1 of the free PCIe lanes that your CPU has (it has 16) and the 660p will also use 1. You won't notice any differences, though

in most all zxxx boards, the m.2 drives run off the chipset pcie lanes, so the cpu pcie lanes won't be used for these drives at all.

that's just talking about the length of SSDs. Both 660p and 970 evo (as well as majority of M.2 SSDs) are 2280, 80mm long.

Thanks guys, that clears things up - i can get a good deal on this drive so glad for the quick responses.

Sometimes the motherboard also indicates the size of the SSD that you can install, the 22 indicates the width of the M.2 and this standard never changes, the other numbers 42, 60 and 80 refer to the length of the SSD.
