Can I Connect A SATA Disk On A SAS Connector On The Motherboard?
Answer : Can I connect SATA drives to SAS connectors? Yes , well known question / answer Does the 6 Gb/s transfer rate means that I'll get an equivalent of SATA 3 (which is important if I use SATA 3 SSDs)? Yes . They will negotiate the speed, slower device wins (12G sas ctrl will lower speed to sata 2 drive if needed) or drive will lower speed to older SAS controller. MSM software (or BIOS) can show you negotiated speeds. Are there drawbacks using SAS connectors instead of SATA 3 ones for SATA 2 and SATA 3 drives? In other words, if the motherboard has both SATA 3 and SAS connectors, what is the reason, if any, to use SATA 3 connectors for SATA drives? Use SAS . Usually SATA connector are part of Intel southbridge. Tests I've done show throughput drops proportionally to number of SATA drives connected to southbridge and results were horrific for 6 drives used simultaneously on Intel southbridge. SAS controller on your motherboard is probably LSI using...
