Bought a new SSD, speed slower than expected

So did some experimenting and research.


My motherboad, an ASUS Sabertooth X79 has 8 Sata ports.

2x Sata3 6.0 Gbps Intel
2x Sata3 6.0 Gbps Marvel
4x Intel Sata2 3.0 Gbps Intel

The first two Intels are taken up by my RAID 0 SSD and they get great performance (~1 GBps read/write).

Now, my new SSD is just a single drive. So when connected to Marvel, he gets 400 MB/s read and a paltry 180 MB/s.
When connected to the 3.0Gbps, he gets 280/260 respectively.

Based on what I read the Marvel Sata3 chips have terrible performance and looks like that appears to be true.
