    Thank you a lot for being patient with me :D

    dd if=/dev/zero of=1g-testfile bs=1G count=1
    1+0 records in
    1+0 records out
    1073741824 bytes (1.1 GB, 1.0 GiB) copied, 4.62269 s, 232 MB/s
    

    This HDD is obviously working fine and much faster than I thought it can. I guess I have to find bottleneck elswhere

    Thank you. The files I download are usually 5-30 GB size. I don’t want to max out my internet speed, I just want to get the files in media library ASAP after requesting download manually (happens maybe few times a week)

    It makes sense, Ill test sequential and random write performance and maybe even test it since I have the hardware available.

    At first I wasn’t aware that my speed is super low for HDD, therefore I was looking for some magic solution with SSD speeds and HDD storage that might not even exist. I have to do more testing for sure

    Thx. Ive seen dd commands in guides how to test drive speed, but I’m not sure how can I specify what drive I want to test. I see I could change “if” and “of”, but don’t trust myself enough to use my own modified commands before understanding them better. Will read more about that. Honestly I’m surprised drive speed test is not easier, but its probably just me still being noob xD

    I have managed to copy with rsync and getting 180 MB/s. I guess my initial assumption was wrong, HDD is obviously not bottleneck here, it can get close to ISP speed. Thank you for pointing this out, Ill do more testing these days. Im kinda shocked because I never knew HDD can be that fast. Gonna reread all the comments as well

    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

    It will download faster to SSD, but then I have to wait the files to be moved to HDD before getting them imported in media server. Im not after big numbers in qbit, I just want to start watching faster if possible. Sorry Im probably not explaining well and Im not sure if Im asking for something that even make sense

    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

    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

    Thx. I use ext4 right now. I might consider reformating, but so many new words to reasearch before deciding that. I heard about ZFS, but not sure is that right for me since I only have 16 GB of RAM.

    Downloads are 100-200 GB max, but less than 40 GB most of the time. I have 512 GB in use and 2TB SSD not in use, can swap them if needed

    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
