Summary: I installed the Synapse card and installed the Dataplex software as instructed. It definitely speeds up frequently used applications and video streaming. However, if your motherboard only has SATA II ports, don't bother with a PCIe card with a SATA III port unless it is a X4 or bigger.
Summary: Ok, I'm conflicted, hard to give it 5 stars when I'm not able to appreciate it properly. I have this on my SATA 3, and my C drive is on SATA 2. But for some reason, the other hard drive on my other SATA 3 is constantly being looked at to boot from, despite the bios showing the order to boot from.
