Data HDD with SSD catch drive (lemm.ee)

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

bcachefs will fill this role someday.

For now there is ZFS which as a cache drive option. Keep in mind it will absolutely destroy the cache drive by wearing out the flash

You also could look into ZFS special disks. However, if you are going that way already you might as well get a bunch of disks.

Ill look into ZFS, but in meantime I found out my HDD is probably not bottleneck. Still want to learn about this so thanks for your comment

ZFS ZIL will not help in this case.
