In addition to two SATA 6.0Gb/s and four SATA 3Gb/s, the X79 chipset originally included support for an 8-port SAS controller. However, just before the release, instabilities in the controller's operation were discovered, as a result of which it was decided to cut down the functionality of the chipset, leaving only SATA ports. Chipset SAS ports are left bypassing Intel recommendations only on ECS X79R-AX and X79R-AX Deluxe boards, but the results of testing SSDs on SAS ports show that 1) - the system is extremely unstable (BSOD), 2) SSDs are slower than on SATA ports.

). SATA/SAS ports are present on the chipset C600
- server analogue of X79.
