G.Skill memory is generally well priced. Well, that's relative given the price of memory at the moment!
This model is CL14, which means that it has a shorter latency than the CL16. Always good to have... for a price difference of 10%.
64 GB for a data server (sshfs, web, nextcloud, git, Linux mirror...) is more than comfortable, but I'm not limited in case of new project.
