Moved provisionally to ePO for faster support.
It states in there for 7.1
Does DE 7.1 support Intel Smart Response Technology (SRT)?
Yes. Data is always safe, even the cached data. The Intel SRT is a smart cache component that only caches frequently accessed data. This is at the sector level and is encrypted by the DE filter driver.
It also states here that 7.x is also supported
It doesn't support Intel IRS though... Rapid Start.. Im not even sure that is in this model.. I have seen no reference as yet to it in the Intel SRT software.
