Re: low 4K-64K with AS SSD

If I understand correctly, this problem shows up after long time use of the drive?


No, in my case it was like I reported (poor) from day 1. Also in my case a secure erase had absolutely no effect.

All this assumes the AS SSD benchmark is sound.

Is it me or my four weaks old SSD is very slow not only in 4k-64k test but in every write tests?

Have you tried different SATA ports:

Yes, Intel SATA 3Gb/s and 6GB/s on my Z68 mobo

Have you tried different SATA cables:

Yes, 3 different cables.

And this drive was "very recommended" by users even though it had this problem?

 

What are the normal speeds for me to consider I have a normal M4? Here's my AS SSD test:

They look very bad to me. Something must be wrong.

Can you try the msahci drivers?

It means I'm not affected by this issue?

MJF thanks for your reply and help, I tried the msahci driver but it's almost the same

We have no idea what PC/Laptop or hardware you are using, which is a must before anything can be determined. Looks like a SATA II connection from the read speeds, but your write performance is terrible.

 

I noticed your previous driver was "nvstor64", do you have a Nvidia chipset?

The pic of your AS SSD benchmark is not showing with that link.

 

This "issue" does not affect everyone, and has certainly not been recognized as a true issue with the M4. I use three M4s and they work great, I have no problems with any of them.

 

The normal performance of a M4 depends on the SATA interface used in your PC, and also varies with the SSDs capacity, smaller capacities have generally lower write performance.
