Do you think it was controller's overhead? I have heard mixed opinions about 3wares. What are the fastest controllers around for MD-raid use?
The fastest setup I have found have been LSI SAS cards - LSISAS3442E-R, with the onboard RAID firmware replaced with the IT firmware. This is connected to port expander based JBOD chassis loaded with either SAS or SATA drives. Regards, Richard
