My hardware is

Backplane http://www.elledi.it/shop/product_info.php?manufacturers_id=&products_id=45914692 AXX6DRV3GEXP

Controller RAID http://www.elledi.it/shop/product_info.php?manufacturers_id=&products_id=54262696 RS2BL040

Hard Disks Seagate http://www.elledi.it/shop/product_info.php?manufacturers_id=&products_id=49990932 ST3600057SS

RAID Bios Console Drive Properties report:

< drive negotiated link speed is less then maximum supported >

then

Drive Speed is 6Gbit/s but Link Speed is 3Gbit/s

why this warning if both Controller RAID and DISKS are 6 Gbit/s ?

6g controller <--> 3g backplane <--> 6g Hdd = least common denomonitor. 3G

In fact, i would set the controller to lock the speed at 3G just to prevent any problems if some how the link was established at 6g
