Moderate needs for 2-4bay personal cloud NAS

[Enquiries]

Thanks for offering some advice!
I've currently got a Zyxel NAS 540 case with four Seagate 6TB ironwolf drives (2 in a RAID, 2 as backup storage)
That unit was good enough, performance-wise for network storage, archiving and the like. It was never good enough software-wise - it's administrative console was one step up from using pure linux commands.
In any evnt, with Zyxel exiting the NAS market, this unit is no longer supported. It's time to get onto something that's actually designed to do the job I need.
Which, primarily is about the administrative management.
Since this is truly a NAS, I need it to be seamlessly supporting PCs and Mac, with good security controls. I need to use smb and afp as well as HTTPS and windows protocols to access it from within the firewall. Externally, I'm using WEBDAV to mount virtual drives when I'm on the road.
The current unit is using 2 1Gb ethernet cables into the router, offering wireless access within our house;
Thoughts?
