So far it's only confirmed across the SATA2 ports, and if the Intel's P67/H67 is used. Where other third-party like Marvell is being used this doesn't affect you or your data. At this point my advice is stay tuned. Personally, I won't want any affected P67/H67 MOBO. So right now I don't have a 100% trust factor on the Intel SATA2 or SATA3.
My thoughts, I'm not an engineer.
