Steam downloading speed stuck at 0KB/s

[Mini Mushrum]

It's been too long since i had that issue, I need help to fix it.
My top speed is 90MB/s but still, steam stops at 0KB/s very often for no reason.

Check the disk usage graph when your download speed drops, you’ll probably find you’re I/O limited. Are you downloading to a HDD or SSD?

HHD, but I have the same issue with my SSD

Is it a SATA SSD or an M.2 SSD?

Sometimes downloads are like that. There is some misinterpretation that downloads should always be a complete zero to 100% at full speed all of the time. There is so much going on between Steam and your drives that no one can guarantee that.

Exactly. Steam is optimized to use as least internet traffic as possible by using diff files and compression. An idle internet connection is not an issue.
If you have a connection beyond 100 megabit/s, you will notice that the bottleneck shifts from being the internet connection to being the drive itself as the data that was downloaded way too fast has to be worked into the target.

Yep, that's the bottleneck for gigabit connections. You need a M.2 drive to keep up with the download speed.

Due to the nature of random access, for such fast connections, the applying of the diffs needs a lot of I/O, in which SATA is too slow.

i have the same issue but don't have gig speeds. its not that.

I'm also experiencing download problems when downloading the Forgotten City. It works if I tried to download Sekiro but the Forgotten City won't continue. Could you please help us steam support team? @Doctor Ice

For a start, steam support ain't here. This is purely a USERS forum.

Second, it could be your drive is too full if you can download one game but not another.

You shoudl NEVER have more tahn 90% of your drive's space used, and when you download a game on steam it's compressed and encrypted so you need up to THREE TIMES the total file size for it to unpack and do it's work.

In other words, if you have say, a 1TB drive and you've used 800GB you have 80% used and are fine. However, if you then try to download a 100GB game, you likely won't have enough as you'd need up to tthree times that, 300GB.

Typically what happens when you're low on space is it won't download, or it will download to the wrong drive, or other weird behaviour./

So, basicaly, what to do ? I'm using a SATA, and I knew about that already Crunchyfrog, so this ain't the issue for me :/

What about AV qurrantine folder then, or missing allow rules "steam.exe"

ps.
if this work in safe boot mode then you have interference issue.
thats what steam call it, not sure a security expert will call it interference, then your own app block you.

well ARK is a known issue, you just dont get the most have way more free room and its here i and other helper disagree how much free space is needed. i use 1 to 5 in unpack ration other say 1 to 3, but both is correct , but there are such things as temp files created in the system doing the process, until it clean up after itself. ( + AV scan or unpack archive sametime, they did that in the past ) + new compression is fare better today then in the past and again what game use it, not that simple, even seen a game devs in the past change packing programm because ppl complaion over it took aged to do.

ps.
in other words your problem to have enough free room , and its funny noone complain then disk is new and empty, you need a faulth disk for that topic.

Dont forget the clear download cache and validate game files, ark is famous for DL issue or change they do.
