I have seen that. Some say yes others say no. I called Gigabyte this morning and the tech guy says its is supported on one of the two SATA controllers and is limited to only 2 drives. On the other hand When I look at the Newegg specs it shows no RAID support for the S3 but there is support on the DS3. But then when I read reviews on NewEgg at least three of the S3 owners said that set up RAID 0.
Here is right from Gigabytes S3 product page.
Other Features Supports RAID 0, 1, JBOD (2 ports with RAID function supported by GIGABYTE SATA2)
Supports @BIOS
Supports Download Center
Supports Q-Flash
Supports EasyTune 5
Supports Xpress Install
Supports Xpress Recovery2
Supports Virtual DualBIOS
Guess I'll see when it comes in.
Thanks for the welcome. Long time reader first time poster(I Think)
