I bought a Acer Predator Helios 500 with a dualdrive Solid state drive - 128 GB, SATA 6 Gb/s Hard disk drive - 2 TB 2.5-inch 5400 RPM system with intel rst tech but I think I changed the settings because the laptop is only picking up the SSD. In windows its like the HDD doesn't exsist. I don't understand the RST thing.
