When I copy some videos from computer to my HDD, speed is decreasing from a good(70MB/s) to less then 600kB/s
I have Ryzen 7 4000, 512GB ssd, kde, btrfs partition, 8 GB RAM
I use this command to measure speed:
time (rsync -ah --progress '~/Videos/' '/run/media/user/HDD' && sync)
I experimented a little and noticed that transfer speed from live cd mode(ubuntu) is good at another notebook(at least 30MB/s), but without changes at mine notebook
I installed Windows as second OS at my notebook and speed was stable enough(a lot of vids - 18 MB/s, one huuge - 35MB/s), I can’t say speed is very high, but in any case It’s better
The most interesting things happened, after I had booted to manjaro back. Usually I was able to transfer about 8 gb of data, then - decreasing of speed. But now I was able to copy 15 GB, part of videos with amazing speed (70-120MB/s), and then just rapid fall from 70 MB/s to 3MB/s and below
I don’t know what to do next, Any help would be appreciated
Thanks
