I recently bought a laptop, from ASUS and the model is S400CA. It says there is a 24G SSD in it used as the HDD's cache.
I found this http://communities.intel.com/thread/34039 and here says "SSD cache or acceleration does not work under AHCI. If you like to enable this feature the computer requires RAID mode. If your computer model does not support RAID then, SSD cache is not supported."
Therefore I checked if my laptop supports RAID mode, but I found that it only supports IDE and AHCI.
But I also looked at the IRST panel, and I found that it says "Disk data cache: Enabled".
I wonder why exactly it can use the SSD as cache without setting to RAID mode. Can anyone explain to me? thanks.
And, since the windows 8.1 is coming soon, so I would like to install it by myself, but I have never tried use an SSD as cache, so I wish to know what I should do before I reformat the hard drive (I want to re-partition it) and install the system. Like should I format the SSD as well? And how could I tell the system that I'm about to install (not sure if I should tell it before installing the system or later)?
Sorry for my bad English.
