Sorry to bring back an old thread, but I've been running into almost the exact same situation and the above link has no new information to help resolve this issue.
I have a Z87 chipset motherboard and have had trouble enabling the Smart Response feature. The SSD is setup properly and the Options ROM shows that chaching is configured on the drive. However in Windows when enabling caching for my HDD, only my two old VelociRaptor drives in RAID0 (same model as above) are displayed as an option in the drop down. I have a new single 2TB WD Black HDD that I am trying to enable this for, but am unable to select it in the IRST software. Neither drive has my OS on it and each have a single partition.
The only major difference between these two drives that I've been able to deduce is that the VRs are in RAID0 and only support SATA II, whilst the new 2TB drive is not in a RAID array and supports SATA III. All of the drives are attached via the Intel SATA controller and both are detected and displayed by the IRST software and driver. I've tried both the newest IRST driver and the one from my OEMs site (MSI) and both have had the same result.
Has this issue been resolved offline? Or is there any new information that can help point me to an actual solution?
Zissou, in order to accelerate the 3rd hard drive using the Intel® Rapid Storage Technology, the hard drive needs to be connected to an Intel SATA port (gray or blue color).
All hard drives, including the SSD you are going to use to accelerate the 2TB WD Black HDD needs to be plug to the Intel SATA controller.
