SSD underperforming

[fluxdeity]

My new 500GB SSD that replaced one of my 128GB SSD's is under-performing according to userbenchmark. According the Samsung Wizard the firmware is latest version. Is there anything else I can do?

Try a different benchmark first.

 

Can you check it in anouther system?

Try a new sata cable.

Ignore it, I did a user benchmark the other day and on run one the SSD was performing well above average and in the next well below. 

 

Unless you notice slow down don't worry about it.

I did another test though and the 4k64thrd results on Samsung Wizard were extremely low as well. As you can see I'm only getting 38 MB/s read and 89MB/s write. It should be over 200MB/s for each of them according to everyone elses userbenchmark scores.

My 4kDQ(64thrd) results are well below the minimums reported by userbenchmark. Haven't tried switching the SATA cable yet, will try a new cable on the same port. My MoBo is Gigabyte 990FXA-ud3 Rev 3.0 so there's no gsata3 ports that I'm accidentally hooking into.

Looking back at the AS-SSD picture i notice that it says pciide - bad. I google around and figured out I need to update my drivers for my motherboard. I guess after my fresh windows install it got wiped. Will report back with updated benchmark.

I have found the issue. The gigabyte 990fxa-ud3 SATA ports 4/5 are IDE and not AHCI. Switching from SATA port #4 to #3 solved the issue.
