I recently bought an Acer Ultrabook, model M5-481TG. It has a 500GB HDD and a 20 GB SSD. After I unpacked it, I immediately reinstalled Windows 7, to avoid Acer's bloatware. Everything is good, except I can't figure out SSD caching.
Really, I'm trying to determine if this ultrabook actually supports SSD caching or not. I thought it did, because some of the reviews mentioned caching. Acer also has the Intel RST driver available for download. However, I've now read that the SSD is only for hibernation. Also, the BIOS doesn't seem to have a RAID option (which is required for Intel RST).
So, does this ultrabook support Intel RST SSD caching? Can it be done with only ACHI? (I'm guessing no.)
If it doesn't support SSD caching, what's the point of the SSD? Should I put my pagefile and hibernation file on the SSD? Should I try and squeeze the OS on it?
20GB is a tad small for the OS. (As reference: My 2 year old install of win7+firefox+openOffice+thunderbird+VLC..etc started out as a 17GB install, it has now grown to 20.3GB) – Hennes – 2012-10-14T00:23:10.710
Reading Smart Response Technology says that SRT (pre-launch name SSD Caching) requires the Intel Z68 chipset and for the integrated disk controller to be configured in a RAID mode and quote "not AHCI or IDE modes".
