Thanks for the links, I'll look into it.
USB is the fall back solution. I'd rather stay with what I already know works well.
I've been using my current NAS with ZFS for over a decade (I've built it late 2008... running with OpenSolaris at the time when Sun Microsystems still existed).
It has survived several disks failures, power supply failure, power outages, etc. without loosing a single data.
I know ZFS with RAID-Z2 is rock solid at keeping data, even through several architectures: used on SunOS, FreeBSD, illumOS, Linux over the years, still the same data-pool created in 2008, imported and upgraded with larger disks every 3 to 4 years.
Daily snapshots (keeping one for the last 7 days, last 7 weeks and last 7 months) saved my life more than once, digging up a deleted file on the fly with very little wasted space. Copy-on-write also saved me more than once with power outage during modification on files. The NAS has been ON 24/7 since I first started it up, except for maintenance and replacing power supply once.
And I want to upgrade the hardware to something newer (and less electricity hungry) but still keep the same usability as the last ten years. I'm not willing to spend thousands, but a few hundreds is fine if it last me for the next decade.
