SSD very slow for Asus P6X58D-E motherboard

[crazy.wingman]

Hi Everyone,

I am having speed issues with my new Samsung Evo 850 120GB SSD.

I have successfully migrated my win 10 onto my new SSD but not receiving speeds as advertised by Samsung 850 Evo.
Currently I get around sequential 267 MB read and 250 MB write speeds, actually I am getting only 50% of speed for my SSD if compared to samsung Evo benchmarks.

I have read a lot of forums on web, and confused what could be the exact reason for slow speeds.

I have benchmarked the SSD with samsung magician tool and AS SSD, both tools are showing the same results.

I have connected my SSD to Sata 3 port "0".
My mechanical 500GB drive is connected to Sata 3 port "1".

and

My mechanical logical 1TB drive is connected to one of the 4 Sata 2 ports.

All drives are on IDE mode, as Drive magician tool is not detecting any of my drives with AHCI mode.
Regarding bios, I have turned the AHCI option on in storage configuration but could not see my SSD displaying there.

Please help me find the root cause of slow speed with my SSD.

Thanks!!

You aren't going to get much faster with that board. It only has SATA2 ports and a couple watered down Marvell sata3 ports. I'm getting about the same speeds with my samsung 850 pro ssd, P6X58D Premium. You are going to need upgrade to a newer chipset if you want faster SATA3 speeds.

Those speeds are fine. Unless you are copying a lot of data from 1 SSD to another, you will rarely see speeds reach that high.

I used to run an 830 on a Sata 2 interface and had disk speed monitors on my desktop. During normal use I only rarely saw it peak above 250MB/s, and even then it was only for a split second so nothing really noticeable.

What is important is your 4k read and writes and the like. They will still be over 100x faster than if a HDD tried the same tasks.

Marvell SATA 3 motherboard owner here; try connecting the drives to the SATA 2 ports. Marvell SATA controllers are not very good.

You won't get advertised SSD benchmarks on an SATA 2 interface so adjust your expectations.

While your in windows IDE mode change the ssd to Ahci drivers.
Restart go into the bios and change the ssd to achi.
Reboot to the bios to recheck ahci mode.
Save and try windows.

Have you tried to do this to enable AHCI?

you need SATA 3

 

[tweakboy]

or AHCI like glare said.

Hi Guys,

Thanks for the replies.

Now, I have backed up my boot drive and formatted the SSD to enable the AHCI mode.
Also restored the boot drive with AHCI mode enable.

Now Samsung magician detects my SSD as AHCI mode enabled and connected to Sata 6Gbps port.

But, still I am not getting performance as compared to as my friends PC with same SSD model. (He has intel i5 4th Gen with intel mobo)
Also checked my SSD performance on his PC, which was comparatively less than his own SSD. (We both have the same SSD model and capacity)

To note:
I have turned on the marvell 9123 controller in bios and turned off the default controller.
Rapid mode is enabled for the SSD


Below I am sharing benchmark of Samsung magician tool.

Of course you don't get the desired speeds, your marvell sata 6Gbit port is not really 6Gbit.

The you won't get much faster storage performance on that board, regardless of using the Intel Sata 2 or the Marvell Sata 3. Using AHCI mode is a start, but you are limited by your boards storage interface. If you need more SSD speed, either get a newer board with true Intel Sata 3, or use a PCIE SSD.

MY SSD is working slow on my friends motherboard too where as his own SSD is much faster than mine. (We both have exact same SSD)
I have tested the SSD on his intel mobo with SATA 3 port with AHCI enabled. I have also tested my SSD raw speeds without any OS on it. (The transfer speeds are also much low than my friends SSD)

Could the SSD be faulty?

Could this happen, how do I check if there is some issue with SSD?

Ummm those screenshots you posted are completely different results than what you stated in your post. They also look to be impossible.
