those are all reasonable points, if I were doing mine again I would spend a little more and go up to 100gbe

if you run all older mellanox gear the cx3 can do the kinda nonstandard 56gbe as well

What are you doing that you need 100gbe?

I am still on 1gbe... I guess I don't transfer anything bigger than a few GiB time to time.

No individual connection other than like a cr tral storage server needs 100gbe, at least for me, but a 100gbe backplane is good for a lot of 1gbe poe devices as an example. With residential fiber/coax reaching 5gb, 1gb is not enough.
