Hello everyone!
I'm replacing my current NAS (a very cheap QNAP TS-212P) with a DIY one.
I already have almost everything: MoBo (MSI H110M Pro VD), Processor (Intel Core i3 7100), reusing the case of a PC I was given at the end of an internship, etc. All I'm still waiting for (and am not fully sure of) is the RAM (which should be in my hands on tuesday). I chose 8GB of DDR4 3000 MHz (I know 3000 MHz is overkill but it was cheaper than slower modules and I was mainly shopping for my main rig with a core i7 8700K so I just added a module to my cart).
I even have my dedicated USB drive ready. All I'm waiting for is RAM and choosing the OS.
I was hesitant between OMV which I already used (on a Raspberry Pi 3) and FreeNAS. I chose OMV just because of the gigantic amount of RAM FreeNAS requires. And this is what bugs me. Why such a difference between the two OSes? I know they don't share the same foundations as FreeNAS is built upon FreeBSD and OMV upon Debian but I'm sure it doesn't explain everything?
All I want to do with it is streaming my personal Blu Ray/DVD rips from the NAS to my TV and my mom's, knowing that mine is a LG Smart 4K TV that connects directly to my current NAS through DLNA, and my mom has a "dumb" Samsung Full HDTV hooked to a Raspberry Pi running LibreElec (Kodi). Eventually I want to make a shared media collection for movies we both love, and one for each one of us (so she isn't bothered with my Star Wars movie collection in example).
Also, I want to protect my data with a RAID1 (software based I guess), but I only have one of the two hard drives for the moment. Can I configure the RAID Array later without losing everything?
Finally, do I need a cache SSD/HDD for storing the temporary data on the RAID array in the NAS? My goal is to have the following HDD configuration:
2 6TB HDDs in RAID1
1 smaller (1 or 2 TB) HDD for temporary/not important data
(if needed) 120 GB SSD for cache.
If anyone can answer my questions, and help me with my configuration, thanks in advance.
Regards.
