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

Are you also talking about incomplete directory in qbit? Doesnt make it faster afaik, but I might be wrong. I havent tried anything yet, wanted to check is it something usual or not worth at all. Got zero experience with using SSD as catch drive, it just made sense to me

Yes, if the temporary directory where the files are being downloaded (incomplete folder) is on the SSD, then it will be faster, especially if you’ve identified a cheap HDD as your bottleneck.

Unless you are incorrect about the HDD being the bottleneck.

Yeah it will be faster, but its extra step before the files get available on HDD.

Even if my HDD is super fast and healthy it would still be a bottleneck for 2Gbps fiber? Ill deffo play with HDD more to find max speeds, wasnt paying attention before because it felt normal to me

Of course it’s an additional step. But it will download faster. Which was what you asked for, specifically in your post above.

If you write directly to your HDD it will take longer to download. If you write to your ( faster?) SSD the download will be faster but yeah, processing has another step of copying.

I’m sorry, but I have no idea what you’re asking.

Best of luck.
