Recently ordered a 128G mSATA in order to replace the supplied one with my U945. I plan to use it as main disk and leave the HDD for file storage.

I am perfectly aware that doing this will surely brake Intel cache functionality (pretty useless if main OS is running from a SSD)

This tutorial states that in order to clean install W10 on mSATA drive I have to disa
ble Intel SRT by changing to AHCI from ISRT on "Sata operation" in bIOS. I am afraid this option is not present in my U945 settings.

Is this important ? All present Intel stuff has already
been disabled at bios level.

And what's up with W10 updated drivers for this particula model of ultra
book ? I see other models of Toshi are receving updated drivers but not for this one
