Steam Write Speed Slow on NVME

[HAZZZZZZA]

This my first time posting anything anywhere, help me steam people, you’re my only hope...

So I just got a Seagate Firecuda Gen 3 NVME SSD drive and installed it into my PC. I cloned my previous SSD (a seagate sata SSD) over to it so I could boot windows from there, and wiped my old SSD to use as extra storage.

Everything was working great and it was super snappy, but for whatever reason, Steam and Origin are writing to it at 500kbs when I download a game.

I checked the bio’s, the drive is set up fine, I even tested it by moving GTA to my old drive at 500mbps, then back again at 500mbps (the speed of my old drive bottlenecks the NVME when moving between them).

When I look at task manager, the network usage of steam is 5mbs but the disk usage is 500kbs. I even disabled lots of background programmes, firewalls (basically turned off Norton completely) but nothing I do will bring the write speed up. Have I missed something here?

Working as intended, actually.

If you're downloading at 5mbps/second, that means the disk write should be around 625KB/second -- Task Manager reports the network usage in bits and disk usage in bytes. So to get the appropriate disk usage, you'd divide by download speed by eight.

note your download speeds are primarily limited by yoru cpu and/or disk write IOs which by the way even on nvme you will never get teh 'maximum' throughput because steam patching does the worst case scenario of read/writes on an nvme so comparing to a siple file copy speed is not indicative of what steam is doing

yeah turns out it was just my connection being very bad and steam was working as normal. I was too hung up on those task manager numbers haha, and didn't realise this was how it worked with steam downloads.

Got it fixed now by cleaning the router out with a can of compressed air.

Thanks all, appreciate the help on this.

This comes up in google as result so ... i necro it for others to see.

In my case my NVME was stuck at 5mb/s and not updating / writing fluent on steam , it did something and then stopped.

this was during the ARK Survival Evolved Updating process.

My fix was weirdly Disabling WIndows write cache on the NVME ENTIRELY
it jumped instantly to 500mb/s writing and the update was done in literarily seconds.

my download speed goes up to like 67 MB/s, the install speed is around 70-90 MB/s and it's about the same after it's done downloading instead of going faster (sometimes goes up to like 120-150 MB/s)

my NVMe should practically reach 7.2-7.4 GB/s write speed, yet it's not

CPU: Intel Core i7-13700K
RAM: Corsair Vengeance LPX 4x16GB (64GB kit) @ 3600 MHz
NVMe: fanxiang S880 2TB

It is a cheap SSD without a DRAM Cache.
Those usually suffer from abysmal performance in IO heavy tasks like processing data.

This thread was quite old before the recent post, so we're locking it to prevent confusion.
