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

40MB/s is very very low even for a HDD. I would eventually debug why it’s that low.
Yes it’s possible. FS like zfs btrfs etc. support that.

It’s probably a 5400rpm drive, and/or SMR. Both are going to make it slower.

5.4k + smr would explain it at write but not at read.

In my very limited experience with my 5400rpm SMR WD disk, it’s perfectly capable of writing at over 100 MB/s until its cache runs out, then it pretty much dies until it has time to properly write the data, rinse and repeat.
40 MB/s sustained is weird (but maybe it’s just a different firmware? I think my disk was able to actually sustain 60 MB/s for a few hours when I limited the write speed, 40 could be a conservative setting that doesn’t even slowly fill the cache)

agreed, I think there is something else going on here. test the write speed with another application, I doubt the drive actually maxes out at 40MB/s unless it’s severely fragmented or failing.

Its the cheapest drive I could find (refurbished seagate from amazon), I thought thats the reason for being slow, but wasnt aware its that low. Im also getting 25-40 MB/s (200-320 Mbps) when copying files from this drive over network. Streaming works great so its not too slow at all. Is there better way of debugging this? What speeds can I expect from good drive or best drive?
Ill research more about BTRFS and ZFS, thx

can you copy files to it from another local disk?

Btrfs doesn’t support using a cache drive
