Built a new system with really good equipment running all sata 3/6.0 gb

Screenshots show my setup and results for benchmark. Before i updated my computer i was running only Sata 2 and got almost same benchmark results as i do now. Something isn't right.

Need help determining the problem, let me know what info i need to provide.

A SSD performance will be greatly affected when it is getting closer to full capacity, I usually suggest never going over 70% capacity. Further, from what I understand the overall lifespan can be reduced a fair bit if you have your drive near full capacity for a long time. I've also noticed that having the Intel C states for power savings disabled in BIOS can make a big difference on the performance of your SSD.

Double-check that your SSD is connected to a SATA 3 (6Gb/s) port.

Samsung Magician in your 1st post has a message that says "You must connect your SSD to a SATA 6Gb/s (SATA3) port for improved performance".

If your drive is already connected to a 6Gb/s port, then connect it to another 6Gb/s port.

The processor listed in the screenshot is a Haswell processor, which means the motherboard must be all SATA 6 Gb/s unless it is something that has an additional SATA controller (like a Marvell) or an add-in SATA controller. Still, it is a good thing to point out, usually this would be the most obvious cause of poor performance.

Ok i ran Crystal Mark and here is a screenshot.

I will next try to move around my SSD on another Sata Port...currently its on a Marvell controller...ill move it to the controller ran by the motherboard chipset see if that makes a difference.

1 thing to note, the D drive says 22% but 100 gigs of data are on my C drive for windows and thats about 60% full
