Quicksync
Yeah, it doesn’t sound like you’re transcoding in a way that’ll show any particular benefit from Quicksync over AMF or anything else. My ‘it’s better’ use case would be something like streaming to a cell phone at 3-5mbps, and not something local or just making a file to save on your device.
DDR4 and no ECC
That’s what my build is: 128gb of Corsair whatever on a 10850k. I’m sure there’s been some silent corruption somewhere in some video file or whatever, but, honestly, I don’t care about the data enough to even bother with RAID, let alone ECC.
I will say, though, if you’re going to delve into something like ZFS, you should probably consider ECC since there are a lot more ‘well shits’ that can happen than what I’m doing (mergerfs + snapraid).
power consumption
A $30 or whatever they are kill-a-watt plus something like s-tui running on the NAS itself to watch what the CPU is doing in terms of power states and usage. I’ve got a 8-drive i9-10850k under 60w at “idle” which is not super low power, but it’s low enough that the cost of hardware to improve on it even a little bit (and it’d be a very little bit) has a ROI period of longer than I’d expect the hardware to last.
I just select the files I want from the bigger torrents, and then proceed to not touch it ever again, unless I want to add more stuff to the downloaded files.
I also don’t move things around - I’m on Linux so all the torrents live in one place with symlinks pointing to where I need/want the data to be as I figured out yeeeears ago that trying to manage a couple thousand active torrents while having the data spread everywhere is a quick trip to migrane town.
