I inserted the card and connected it to my bootable SSD. Got a bootmgr error. So I unplugged it from the boot drive, reset it, and booted by plugging it into the data disk. Booted, hard drive found. AND THE DRIVERS WILL BE INSTALLED AUTOMATICALLY. After reboot and shutdown. Boot drive plugged in. All hard drives in the bios were shown. Then Windows booted normally. speed increased. I ran Disk Speed Tester before and after and saw a 50% increase in data transfer speed. So I'm happy. it works well. It adds a DOS boot screen and plug-n-play swap functionality to Windows. I have two SSDs connected to it and access works with both.
