but you originally mentioned explicitly it was for NAS - this is misleading.
I tried first with one dual core CPU low end motherboard with 4 SATA ports,
4GB RAM and 100Mbit connection at home - also multipurpose - didn't work
well. Now I have 4CPU with 32GB RAM and 2 LSI SAS controllers and 1Gbit
network. Now it works! I have 3 PCs and a popcorn. If all work together and
I also compile something, you feel it from time to time.
What I want to say is that these low power CPUs have their limits and might
be also not sufficient for multipurpose - well depends on the "multi"
Also consider NAS disks like the WD Red series. I stick to the 2TB (WDC
WD20EFRX-68) cause the 3 and 4TB fail more often according reports. With
those I never had issues in the past 5-6y and they are significantly more
performant especially when reading. I had few Seagate that died and I have
also 1TB WDC WD10EACS-00 Green, they are may be 8y old and survived, but
have worse performance.
The SSDs are rather expensive or better were, but they also tend to totally
fail
If you go for the arm based solution you should consider the board also and
look into the details - latency, cache, memory access speed and the bus to
the drives - which is exactly the problem if you do not get a proper
controller. In this context the FreeNAS makes a lot of sense, because it is
optimized. The configuration I described above consumes 80W when idle. Each
virtual box I starts adds about 10%. A NAS only solution would be very
power efficient compared to this.
