[SOLVED!] Samsung 830 slow (read) speed?

Hi guys

I've got my first Hackintosh running (G5-mod) and everything is great. Everything besides Youtube-playback and SSD performance. I believe I'm supposed to reach around 500mb/s read speed with a Samsung 830, but I'm only getting about 300 running on Sata 3, which isn't much better than my M4 running on Sata 2. What can I do to improve this result?

Thanks for reading!
Mathias

Anyone?

I'm getting 370MB/s sequential read, 230MB/s sequential write in both BlackMagic and AJA, with my Samsung 830 256GB.

According to Samsung it should reach 520MB/s, which is why I want more from it

I'm wondering the same thing. Though in my case, I'm stuck with the Marvell 88SE9123 SATA controller, which may be the bottleneck.

SOLVED!!

Thanks mate, you sorta gave me the answer there. I changed my SATA-ports from the Marvell-one (which I had it connected to before) to "the other one" and gained like 100mb/s reads, which still isn't 520mb/s, but I feel it's acceptable now. Here are screen shots from before and after changing ports.
