Hi,
I'm Davis from ASRock HQ TSD.
We tested ASRock Thunderbolt 2 AIC card on X99 Professional as below.
We installed the Thunderbolt card and connected to Seagate GoFlex® Desk Thunderbolt™ adapter.
And installed a disk(WD1001FALS) on the adapter, the system is able to detect the 1TB disk as normal.
