I have a Samsung NP530 ultrabook. I am planning to dual-boot the Win7 on it with Xubuntu 12.04. The ultrabook has a 500GB Hitachi HDD and a 16GB SanDisk SSD. I can see the HDD in BIOS, but not the SSD. Using GParted from the LiveCD, I could see the HDD and SSD as sda and sdb respectively. The layout is described here.
From this LinuxMint forums link, it seems that the SSD is used transparently by Win7 to boost its performance.
Your Windows system probably uses Intel's SRT technology.
Blazing performance on Win7 is not needed - it will be used for the odd Android device rooting utility. If I want to keep dual-boot, and yet use the SSD for Linux, how can I turn off the Intel SRT boosting?
