SSD slow write speed

[matheo1234]

Hi there.

I'm facing a problem with low write speeds on my Intel 540s 120GB ssd.

This issue happens on High Sierra 10.13.6 and on Mojave 10.14 , too. It happens also on hfs+ and apfs.

Here is a screenshot of the speeds.



Need your advice.

Thank you.

Intel SSDs are a poor choice on hacks. Better result with other OEMs such as Samsung.

Note also:
Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.

I'm facing the same thing on Windows 10. Also , I tried another ssd (Samsung 830) and it shows low write speed , too. So , maybe it has to do with my Laptop after all.

AJA shows that maximum write rate is 489 , but it is not consistent.
What is happening ?

Hardware problem/limitation.
