SanDisk SSD Plus extremely low 4k read speeds

[Draken21]

For some strange reason I am facing the issue below. Problem is that the SanDisk is my main disk with all the games installed into it. Any easy solutions to suggest?

Crucial C:

Integral E:

Samsung F:

SanDisk (the problematic one) D:

I do understand that the Samsung one might be lying a bit but the difference between all disks (including the cheap Integral one) and the SanDisk is massive. Same happens with any benchmarking program I try. Obviously the cable/sata/etc is not the issue cause the sequential read speed is just fine.

Any ideas?

Random 4K writes are not important for gaming. If you were using this disk with a database, it might be different, but with 500MB sequential reads, you shouldn't be impacted.

Thanks. But I am still trying to understand why the huge difference between the drives and also the reason the write speeds are higher than the read ones.
