write speed seems slightly on the lower side though, maybe some activity in the background?

jelouuu, is my ssd fine? its working at his 100% speed?, i dont know about ssds i have Ssd 500gb Western Digital Disco Duro Solido 2.5 Laptop Pc WDS500G3B0A

 

this is the test i made, is read/write/speed etc ok? how do i know if its not working at its max sppeed/read/write?

Those numbers look perfectly normal 👍.
Your WD Green/Blue SATA SSD is rated around 550 MB/s read and 500 MB/s write, and your CrystalDiskMark results 552/517 line up exactly with the spec.
Keep in mind:
Random 4K speeds like the last two rows are always much lower, that’s normal, not a problem.
Being a 2.5 SATA drive, it will never hit NVMe speeds thousands of MB/s, so don’t compare it to M.2 NVMe results.
As long as the drive health in CrystalDiskInfo says 100% or Good, and you’re seeing 500 MB/s sequential speeds, the SSD is working at full performance.
So yes, your SSD is fine and running at max speed for its class .

Writes will suffer some as the SSD increases in capacity usage. For example, you're at 80% full on that drive. So when a write operation occurs, there's less free cells to write back to NAND flash simultaneously. It's normal to see that.

so how much full must be this ssd to have the 100% speed performance? 80?

It really depends on the SSD make/model. But generally as your SSD fills up its storage with little free space left, the write-back performance drops. Usually because of needing to zero out the cells before writing your data to it. Also there's wear-leveling algorithms where data is shuffled around which also incurs a performance penalty.

 

Exactly what's the most you can store while maintaining maximum write-back performance isn't really known. I usually keep my SSDs no more than 70% capacity.

It's ok to fill up the SSD if you need too. Just understand performance writing data will drop.

Reading data on the other hand shouldn't degrade regardless of how little or how much you have stored on the drive.
