"I am pleased to announced that starting version 1.0.2, EasyNAS will support RPI hardware on 64bit (can run on RPI4, RPI3b). This is a huge step into bulding a DIY NAS from RPI, I’m planning to buy a kit and build a great NAS based on EasyNAS. The current RPI version will only support ethernet , but I’m planning to add wireless support" -Yariv
