Opinions on large scale RAID or drive pools

Hey everyone,
So i currently have 32TB of raided drive space (RAID 5), that i am needing to replace. Combination of just old failing equipment and needing to upgrade. I am running it under windows server 2008 R2, and an LSI MegaRAID card plugged into a SAS expander. It acts as both media and business storage for my small business, but i've generally moved all my business stuff to cloud storage like one drive. So my home server is mainly used as a plex media server/storage.
Since i still get pretty good read/write performance out of it, i would like my next server to have that as well, what i'm now questioning is what kind of software i might run it all on. I have been looking at FreeNAS for quite a while and was planning on building the next server out of that, but the initial investment is really high and might not be feasible for me for a little while. You need server grade hardware (ECC-RAM, and therefore server motherboards and such), and you need to get your entire drive pool immediately as you cannot extend or change volume size once the drive is created. But all i need is SAS or SATA ports, no RAID cards are needed. That simplifies the setup a bit.
I also was looking at just building a windows 10 box with a HBA card and running Storage Spaces. But i've never used it, and all i've found online is that in parity mode the write performance is dismal. It also has stated that you can only do RAID 5 type parity, which i am not very keen on as its causing me potential headaches with my current setup (since the LSI MegaRAID setup is quite particular about what drives i can use, it takes me weeks to get replacement drives as they are all 3TB entry level enterprise drives and i can't get those easily in my city, during those few weeks, the potential for another drive failure is quite high). But this solution very much simplifies the hardware i need, as i can just use any decent spec hardware. I also like that it allows me to spec the logical drive size to any size want up to 64TB and then just add drives as i need the space.
My plan is to use 10 8TB WD RED drives in my next server, in a RAID 6 configuration. So i would really be interested in anyone that has used either FreeNAS or windows 10 storage spaces, or really anyone that has built servers out of other solutions (like unraid or anything else) that might be able to help me make a decision.

I agree with the above...consider a Qnap or Synology.

A year ago, I was considering a full rebuild on my house server.
Was a Win 10 box, with an older Pentium G840, 8GB RAM, bunch of drives, etc, etc

Was looking at a Server2016, i7 CPU, etc, etc...

Ended up with a Qnap TS-453a. 4 x 4TB drives, RAID 5.
Featurewise and pricewise, it crushed the Server2016/i7 concept.

Those things are no longer just simple storage boxes. Plex, music, dedicated Home folders for your desktops, etc, etc.

If/when I need to expand...either larger drives, or another similar Qnap. The Qnap OS can see multiple boxes as one large drive pool.
 

Yeah even the new QNap's have HDMI out. Amazing!

I have used solutions like that in the past. Do not like them. I find them underpowered and overpriced for what you get. I need to be able to run it as a plex server and potentially able to handle multiple HD transcodes. Those NAS devices just aren't able to do what i want them to do. Especially considering the size i want to do it in. The few pre built NAS devices that have the number of bays i want are ludicrous in their pricing. If i'm going to spend that much on hardware, i prefer to be able to dictate what goes into it.

Not really into dual purposing a machine. I like my file server to be kept as a separate unit. I don't really have use for virtualization outside what i do for work, and i do that all in Azure and AWS since they are much better suited to business applications.
I did take another look at something like the synology 2415+ and the QNAP TS-1635. They are actually pretty intriguing, but pretty expensive. They cost more than i could build a machine for. And expanding them with expansion chassis gets pricey too. They seem to have come a long way however, and might actually be a viable solution. Definitely more plug and play friendly than building my own.
So i guess i still have absolutely no idea what i'll do. :p

Yes, the -1635 is pretty damn pricey.
Which is why I suggested one of the smaller 4 bay boxes.

4 x 8 or 4 x 10TB drives. Expand as needed. Either with a dedicated drive expansion box, another compatible NAS box, or a 4 bay USB enclosure.

Won't be doing any of the 4 bay. I'm at 32TB of data now, and thats just going to grow. Want at least 10 disks since i want something that is going to keep for 4 to 5 years without any worry about drive space. Expanding 4 bay enclosures, the price is just going up exponentially with every expansion you add. They add up to basically the same as a single 12 bay enclosure.
