Data HDD with SSD catch drive - eviltoast

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

    qbittorrent moves the completed files to the assigned literally as soon as it is done.

      but if the disk is actually bottlenecking at 40MB/s it will still take time to copy from the SSD. That plus the initial download to SSD will just end up being more time than downloading to the spinning disk at 40MB/s in the first place.

        I doubt the disk will bottleneck at 40mb/s when doing sequential write. Torrent downloads are usually heavy random writes, which is the worst you can do to a HDD.

        That’s not how hard drives work, and doesn’t take into account that OP might want to download more than one thing at a time.

        Hard drives are fastest when they are moving large single files. SSDs are way better than hard drives at lots of small random reads/writes.Setting qbittorrent up so that all the random writes inherent to downloading a torrent go to a small ssd, and then moving that file over to the big hard drive with a single long writer operation is how you make both devices perform to their best.
