Nome SSD and motherboard compatibility

[nuclear465]

Hi there.

 

I have this motherboard: gigabyte aorus x470 ultra gaming. It has 2 m.2 sockets for nvme SSD. My M2A_SOCKET is already populated with an adata xpg sx8200 pro 512 GB and i get full rated speed. And i would like to get a second nvme SSD (adata xpg gammix s11 pro 1tb) the rated speed is 3500 MB read/3000 MB write, it's similar to the sx8200.

 

I was wandering if the the second nvme SSD in the M2B_SOCKET will lose performance since it's PCIe 2.0 instead of PCIe 3.0. Maybe i should get a cheaper and slower nvme like the wd blue sn550 if i am going to lose performance on that socket anyway.

 

motherboard specs states this:

1. 1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe 3.0 x4/x2* SSD support) (M2A_SOCKET)
   * Actual bandwidth may vary by CPU.
2. 1 x M.2 connector (Socket 3, M key, type 2242/2260/2280 PCIe 2.0 x4/x2 SSD support) (M2B_SOCKET)
3. 6 x SATA 6Gb/s connectors
4. Support for RAID 0, RAID 1, and RAID 10

PCIe 2.0 x1 = 500MB/s

Theoretically you are limited to 4 x 500MB/s.

It will only run at a maximum of x4 PCIe 2.0. 4 x 5 Gbps x 8b/10b encoding x .9 overhead = 14.4 Gbps = 1.8 GB/s. This only impacts sequentials however, yes, the 1TB SN500 would be a good fit.
