Motherboard: Asus ROG MAXIMUS IX HERO
CPU: Intel i7-7700k
RAM: 64 GB

Hey, I've just checked my Samsung 970 Evo 500GB SSD drive speeds and it's looks like drive is terribly slow. What can I do to speed it up?

Crystal Disk Mark:

It's looking like write speed is capped at 700MB/s

Crystal Disk Info:

AS SSD Benchmark:

I've installed SSD in M2_2 (this is screen from motherboard manual):

read look fine. write is slow. how full is the ssd?

You're writing directly to the TLC flash, the Drive is too full I think.

You can see on first screenshot that drive is 78% full.

You're writing directly to the TLC flash, the Drive is too full I think.

Dip in those speeds are with 1GB test files, those test dindn't copy 20GB+ of data.

So how much data is optimal to store on ssd drive without writing speed compromised? 60%?

what the os?

Can you run WinDirStat as Admin and let us see how full the drive really is.
W10 is notorious for not showing the real usage.

Right now it looks like this:

did you use the samsung tool to check ssd health?

Not all M.2 slots are the same... You have to understand that your SSD and motherboard are M.2 SATA types, not M.2 NVMe ports. As such, the performace will be a lot slower than NVMe SSDs (~600MB/s) which are up to six times faster (~3500MB/s)...

both the motherboard and ssd is pcie
if you look at the first post, his read is about correct, just the write is slow.

I couldn't use Samsung Magician on this drive:

But I checked with HDDScan, and here results:

Yes, it was a problem with amount of data on the drive.
