I just gave a try to OMV on an old Atom mini PC and I'm impressed by the ease of use and the flexibility of OMV. Really great !
Now I need something more serious. My needs are quite basic:
1) backup of personal data
2) media library for a Kodi box
I already have an external backup (through ssh) located at my workplace, so I believe a single disk NAS is OK for me (different places, different systems: the probability of a simultaneous fail looks negligible to me).
It looks that the Odroid HC2 is among the best choices for price/performance/energy efficiency. I read this post Which energy efficient ARM platform to choose? and I learned a lot.
About the above post by tkaiser, what does mean "local storage performance" ?
My main question for now is the choice of the HDD. I need something around 4To, but I'm a bit lost among the different characteristics (speed, cache...): what are the important things for use in an OMV NAS ?
Also the HC2 accepts both 2.5" and 3.5" HDDs, but 3.5" ones are usually cheaper. Is there any advantage of using a 2.5" ?
Thanks a lot !
