SSD operating bellow expected performance

[IndioBravo]

Hi everyone!

 

Simple question, I recently made a fresh windows install, got all set up and made a benchmark. Everything works fine, except my OS SSD, which is bellow expected performance:

 

 

Is there anything that I can do to make it better?

 

 

Thanks for the help!

Run a proper disk benchmark like CrystalDiskBench and see if your performance is good.

Honestly I wouldn't worry about it. Random performance is more important for single user OS usage and it looks about where it should be.

The sequential numbers are definitely good for that drive, the random numbers are toward the lower end of normal but it's the deep queue speeds (175MB/s when their test should be reporting >300MB/s for an 860 Evo) which are getting you the "below expectations" remark. Also despite the initially good sequential values your sustained writes show a larger than expected fall off when run repeatedly.

 

Given those two factors the first thing I'd check is what temperature the SSD is reporting during the benchmark, it feels a lot like the controller is overheating under high load and throttling down. Check that the drive has adequate ventilation.

How good or bad is 53C? For the SSD under load.
