I have a 900gbps connection, should I just allow like, 30 downloads in qBittorrent at once to try and max it out, or will all that writing to disk reduce the download speed or something?

 

Just trying to optimize my downloads.

 

Thanks

Another question; will there be any difference in using a 3,500mb/s NVME drives in raid1 for the cache versus 7,000mb/s NVMEs? because the former are liker £25 and the 7k ones about £70.

Set it to 99 downloads and see.  In my case with a 400mbps connection, I see no difference between 50 and 99.

 

For nvme write speeds... I don't think gen 3 or gen 4 would be noticeable in your downloading endeavours.  

Not for downloads but for the cache drive - will gen3 vs gen4 be noticable at all? does unraid actually use all speed available or is paying more for faster NVMEs a waste? 

 

Like right now I have 2x 2TB SSDs which my plex stuff is on and that's at 510gb now, will swapping them out for a couple gen 4 nvmes be noticable?

 

Thanks

Would depend the amount of streams.  Try to max out how many streams you aim to host and then check the drive speeds on your nvme under main.  Should give the a reasonable answer.

Currently my downloads go to the array. I've bought a 4tb NVME to use as a download drive because I noticed having downloads on while doing a parity sync made it slow to a crawl.

That's certainly a good idea.  Let mover take care of it's thing when nothing is going on.

Yeah that was it really. Downloading and even just having 2 torrents active would slow it from 220mb/s to like 30-40mb/s. It levels out at close to 200 now but strangely it still can go higher if I disable docker and have none of them doing anything to the array (like watching something on plex etc)
