    6.0Gb Drives on ICH7R/DH (RAID 5) only have 1.5Gb SATA transfer rate

    Ptochos

      I've got three 1TB drives (WD1002FAEX) in a RAID 5 array. It is running Server 2003 R2.

       

      In the BIOS (and during boot) they all three show up as 3.0Gb/s.

      The "Rapid Storage Technology"  console shows each drive as "SATA transfer rate: 1.5 Gb/s."

       

      These are generation 3 SATA drives, and are capable of 6.0 Gb/s. They are limited to 3.0Gb/s by the ICH7R/DH.

       

      I have tried all the recent drivers and  "Rapid Storage Technology" consoles, but they always show up as 1.5 Gb/s.

       

      Can anyone help me get these up to 3.0 Gb/s ?

      Are the consoles just reporting the wrong speed?

       

      Thanks for any advice...
