No RAID option in Intel's RST - Dell Latitude E6440

Hi,

Core i-7 4810MQ, 16Gb 1333Mhz, 4600HD

I wanted to set up a normal RAID 0 array with 2 identical SSDs, however RST only gives me the option the create a recovery volume. I did update the driver and I enabled the RAID On option in the BIOS. I don't really know why it's not working.

I'd really appreciate it, if you could help me.

Thanks,

Benjamin
