Can I connect a SATA III drive to a SAS controller and get the SATA III performance? Will I see slower performance from the SATA III drive by using a SAS controller than a SATA III controller?
If the SAS controller supports sata3 you can, If not it will go back to sata2. If the disk is not a SSD or in a raid you will never get sata3 or sata2 max speeds
Name on your sas controller ?
