Using Windows 10 Pro. My m.2 SSD drive gets about 450 MB/s random access read/write performance in benchmarks. But in real-world usage peaks out at about 50.I'm using a Ryzen 3800x and I've assigned 4 PCIE lanes. Why is my real-world performance so bad and how can I improve it?

Samsung SSD 970 EVO 1TB

NTFS formatted, compressed, and indexed

That's where your problem is. It's advised not to use Windows software compression and let the SSD controller manage that (it does that automatically under the hood).

Make sure to check you don't have some SATA devices on a port that also shares the PCIe lanes with the M.2 port.

Okay, I'll try that

Decompressing (14 hours remaining) lol

Check your motherboard's user guide settings to make sure the M.2 port isn't shared with another SATA device. If that's the case, move your SATA device to another port to free the PCIe lanes for the M.2 port.

Compression and indexing take up a lot of overhead. I'm saying this without knowing exactly how you accomplished those things. Been in IT for about 15 years. I've never compressed an hard drive and I leave the indexing at the default out of box level.

Install all BIOS updates, and any updates you can find from AMD for the processor. I know AMD chips have issues related to performance that are only fixed by updating firmware and drivers. They're great value but seem to require more tweaking than Intel chips.

Also install the Samsung management software and enable Over Provisioning on the SSD. You never want to use up more than 80% of the storage capacity on the SSD for an extended period of time. If you're doing backups or moving data around it's fine for a few days to be above 80% but it does absolutely destroy performance and greatly reduced the life of your SSD.

Can confirm. Ran a couple of ssds into the ground being mostly full for just a few weeks.
