Hi folks. Just noticed a weid thing with my M4s in RAID 0. According to the Intel Rapid Storage Technology program one drive is running at 6Gb/s and the other at 3Gb/s. Does anyone know why this would be?
 
P67A-UD7-B3 SSD issues.

Hi folks. I have a Gigabyte P67A-UD7-B3 with 2 Crucial M4 128Gb SSDs connected to the 2 white Intel chipset SATA III ports. I have just installed Intel Rapid Storage Technology which is reporting the drive connected to port 0, with the OS on it, is running at 6Gb/s which is fine! Now the issue. The other drive is connected to port 1 but is only running at 3Gb/s. BIOS is set to AHCI and I am using SATA III cables. What I can't figure out is if its an issue with the SSD, the SATA cable or if the motherboard is developing the SATA degradation issue that caused the original P67 boards to be replaced. However my original UD7 got replaced with a B3 so surely this can't be the issue?
 
Maybe it's a bad cable? Switch them round and see if the other drive then throttles back to 3Gb/s.

If it does, maybe it's the port? Switch ports -that could mess up the RAID config - take an image and restore?

If the same drive still throttles back having changed cables and ports, you have to assume it's a problem with the drive itself.

Do you have the latest firmware installed on both?
 
Have you Tested your drives with diffrent speed software like disk bench or ATTO Disk Benchmark to see if there is a diffrence.

On a side note, the drives are not in RAID anymore, if I wanted to put them back into RAID 0 could I create a system image incorporating both separate drives onto a back up drive and restore onto the new RAID?
