I've built my first pc 1 week ago but today I saw that the ssd is running at half speed.. So I checked and it seemed that I've connected the ssd to SATA 3GB/s (don't judge me first build ) so I changed it to 6GB/s but now the boot time takes 5+ minutes (before it took seconds to boot.) I'm using Samsung EVO 840 120GB and ASROCK z87 Extreme 4 and everything seems normal with the ssd
