After upgrading my internet connection I immediatelly noticed that my HDD tops 40 MB/s and bottlnecking download speed in qbittorrent. Is it possible to use SSD drive as a catch drive for 12 TB HDD so it uses SSD speeds when downloading and moves files to HDD later on? If yes, does it make sense? Anyone using anything simmilar? Would 512 GB be enough or could I benefit from 2TB SSD?

HDD is just for jellyfin (movies/shows), not in raid, dont need backup for that drive, I can afford risking data if that matters at all

All suggestions are welcome, Thx in advance

EDIT: I obviously have upset some of you, wasn’t my intention, I’m sorry about that. I love to tinker and learn new things, but I could live with much lower speeds tho… Please don’t hate me if I couldn’t understand your comment or not being clear with my question.

HDD being bottleneck at 40 MB/s was wrong assumption (found out in meantime). I’m still trying to figure out what was the reason for download to be that slow, but I’m interested in learning about the main question anyway. I just thought I’m experiencing the same issue like many people today, having faster internet than storage. Some of you provided solutions I will look into, but need time for that and also have to fix whatever else I’m having issue with.

Keep this community awesome because it is <3

    Any HDD should be able to get at least 100MB/s sequential write speed. Unfortunately torrent writes are usually very random, which just kills hdd performance. Multiple parallel downloads or concurrent playback from the same disk will only make it worse.

    Using a SSD for temporary files will absolutely help. It should be big enough to hold all the files you are downloading at any one time.

    You could also try to find a write cache setting that works for you. That way what would usually be many small writes can be combined to bigger chunks in memory before sending them to storage. Depending on how much ram is available I would start at 1GB or so and if it is still bottlenecking try in- or decreasing until it improves. Of course always stay in the range of free ram.

    Back when I was torrenting (ages ago) write cache helped a lot. It should be somewhere in the settings menu.

      My solution to this was to put the default download folder on an nvme and then move the torrent to a storage hdd after completion

      Oh, you are talking about torrent client settings? I could spare 1-2 GB of RAM, but not more than that (got 16 GB in total). I see this might help a lot, but I would I still be limited with HDD max write speed? Using SSD for temporary files sounds great, but waiting files to be coppied to HDD would slow it down if I understood correctly
