Slow SSD Speeds

[Glowbit]

Hi, I am getting slow speeds with my OCZ Agility 3 120GB, it says up to 550MB/s, I know this is the max speed, but at least I should get 300MB/s. http://prntscr.com/674jmm

What do I need to do to get the max performance?

Specifically, what SATA port is it connected to?
SATA II, SATA III?
Native AMD, or Marvell?

And is this a new condition, or has it always been this way?
How full is the drive?

SATA III navy blue ports.

It has always been this way. It has 70GB of free space.

All of your ports are SATAIII, so no problem there. I would try swapping the drive to the gray ports, see what that does. Also check the settings for AHCI in the BIOS.

I just did a quick search, see this thread. Supposedly that drive simply isn't as fast as stated.

Yes, there apparently problems with that line of drives.

Now it's connected to the grey port but the speed is the same. So what do I have to do? Install an old drive version?

The connection is fine, if you read through the link above, it explains that your drive is simply slower than advertised, when using these benchmarks.
