DLNA server - SSD caching

[MotleyCrew]

I'm in the process of replacing our family desktop PC and among other things, want the replacement to work as a DLNA server, to store our home video projects, ripped DVDs and music, digital photos, etc. The idea is to have access to this content from a DLNA-compliant device connected to our TV or directly from a "smart" TV.
The replacement PC (Windows 10) will have an SSD primary drive, with one or more larger capacity spinning rust drives for media and other data. For energy conservation, I'm interested in caching options for media served up by DLNA. The idea would be to have the server use some capacity of the SSD as a cache to temporarily store "queued up" media, allowing the traditional drive(s) to spin down and conserve energy and avoid unnecessary wear. For longer queue/play times (e.g. full-length movie), it would also be nice if the TV or TV-connected DLNA client would do local caching, so the server could go to a low-power state. Ideally, the server and drive(s) would transparently wake/spin-up as necessary.
Are such features available in Windows or third-party software/hardware? It looks like many (most/all?) DLNA clients support caching of some form. I'm guessing power settings + wake on network activity on the server would answer one concern I mentioned. So maybe the idea of also caching to SSD on the server side is unnecessary...

Thoughts, tips, suggestions are welcome--thank you!

Windows 10 wont use the ssd to cache the DLNA content. I think you will need to use something like PLEX which can ssd cache, I'm just not sure how much of the actual streaming content it will cache.

Faster performance, um... OK but energy saving? Would you be surprised that a spinning 3.5" drive consumes a mere 9 watts? that's what I measured on my 2TB seagate. The major energy consumption is on spin-up, so you gotta weight whether "cruising" mode or constant spin up/down is better.

A sidebar about DLNA is, I hate it. Usually the TV had got no umph to do things smoothly. Jumping from media to media takes forever, trying RW/FF may freeze. DLNA OK to wet appetite but am much happier with my HTPC. I know HTPC going out of vogue (a little difficult to configure at first), but my FF goes full speed
