Mirror vs mirror gen 2

Hi, what are the differences between “My Cloud Mirror 4TB” and “My Cloud Mirror 4TB Gen 2”.
Thank you

The Gen 2 has a newer and faster dual-core processor compared to the Gen 1, which is single-core.

Either are fine for file serving, but the Gen 2 should run the services and apps better than the Gen 1 (I say should as I have a Gen 1, but don’t use many apps either).

thanks Darrel, with the reply I have solved some doubts, I will buy gen1.
