SSD and RAM Recommendations for Legion 7i Gen 9

Hey everyone! I’m looking for recommendations for an M.2 SSD for my Legion 7i Gen 9. I have two slots available, but I’m not sure if the second slot has a different size. Any advice on which SSD would work well for both?

Also, I’m planning to upgrade to 32GB of RAM. Any suggestions for good RAM to pair with my system?

Thanks!
