Does anyone know why. I was using two Crucial M4 drives that showed they were running at 6Gb/s.

Are the Intel® SSD 530s connected to the Intel® Z97 chipset (gray ports) or the ASMedia* SATA controller (black ports)?
Where did you see the Intel® SSD 530s running at 3 GB/s? Can you provide a screenshot?

The drives are on the Intel Z97 chipset. I got the 3Gb/s from the Intel Rapid Storage Manager applet on the advanced tab of the drive information. I installed Crucial drives on the same ports and they showed as 6Gb/s transfer rate. I don't have a screenshot because I installed the Intel drives in an X58 System for now, until I can figure this out. I created a system image so I can restore the drives when needed.

Do you have the latest BIOS, https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18363 Intel® SSD firmware, and https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24293 Intel® Rapid Storage Technology?
Do you get the same result when the drives are not in RAID or when they are connected to the ASMedia* controller? You may need to use a similar application (designed) for the ASMedia* controller since Intel® Rapid Storage Technology will not see the drives connected to it.

I installed the drives on an X58A board. It has a Marvell SATA III RAID controller. The Marvell RAID Utility shows the drive speed as 6Gb/s which is what it is supposed to be. I tested the drives with ATTO and found the Z97 chipset to be substantially faster than the X58 Marvell. I still don't understand why the Z97 IRST shows the transfer rate as 3Gb/s. You would think that an Intel SSD running on an Intel chipset using Intel software show the right information. I have the latest firmware on the drive and the latest BIOS and IRST software. I took some screenshots which I have enclosed.
