The Samsung 830 SSD drive is blazing fast. My computer didn't have any Sata 3 connections on the motherboard, so I used an empty PCI-E x 1 slot to add a Sata 3 controller. Using that, I got a perfect 7.9 on the windows experience index score (7.9 is the best score possible currently). Using an Intel 320 series SSD, I had a 7.4, and using a Kingston SSDNOW V100+, I had a 7.0... so this Samsung 830 is a step above and beyond other SSDs. Everything on my PC seems to happen instantly now.
