Even more information ! quote "She may be only looking at one hard drive at a time too. But, I have two drives not one. So take the speed she sees and multiply it by two and we get PIO * 2 = X. X would be the true speed overall. What X is I do not know. I will come back to this in a while when I get more information."
The PIO speeds can vary from 3.3 to 16.7 MB/s ( http://www.pixelbeat.org/speeds.html ),So the formula can be 3.3 * 2 = 6.6 MB/s for the low side. Here is the high side 16.7 MB/s * 2 = 33.4 MB/s I have HDTACH reporting an AVG read of 68MB/s and HD Tune reports 34.1MB/s AVG speed.

More interestingly (FYI) I found the manual for the mobo stating the PCI CLOCK speed is 33MHZ Which can be translated into MB/s using this formula from TomsHardware here > http://www.tomshardware.com/forum/187317-28-speed "PCI = 33Mhz x 4 bytes (32 bits) = 133MB/s AFAIK everything that rides on this bus would be " shared among other pci devices. " sound card, ethernet card etc... (thanks tomshardware).
The first place to check should have been the BIOS for the RAID controller, which I have found is integrated in to the mainboard BIOS. I also found to properly update the BIOS the RAID controller should be enabled in the BIOS and set to RAID (no links for this yet). I do have the updated BIOS version F11 (mobo BIOS) and I see the ITE BIOS is v 1.71 with a firmware version of 02093030 I may try to reflash the BIOS with RAID enabled this time, after backing up of course.
