trying to find out if this is correct. have all data backed up and waiting for my asus x99 deluxe and 5960k to arrive. want to get things planed so I can get the set up right the first time.
The X99 PCH itself exposes 10 SATA ports. Many motherboards will include additional SATA controllers which are connected to the PCH via the PCH's PCIe 2.0 lanes.
The X99 PCH can be used in conjunction with Intel's Rapid Storage Technology ROM to configure the PCH SATA ports in a raid configuration.
The limit of the total number of installed drives is the lesser of 10 and the number of exposed ports, but there are other limits which apply on a per-RAID-volume basis. These limits are:
RAID-0: 6 drives maximum
RAID-10: 4 drives only
RAID-5: minimum 3 drives
So while a single RAID-0 volume cannot span more than 6 drives, it should be possible to construct a pair of 5-drive RAID-0 volumes on a motherboard that has all 10 of the PCH ports connected.
