Review on High Point RocketRAID 640L Internal 4 SATA Port RAID Controller -Lite Version: PCI-Express 2.0 x4 SATA 6Gb/s by Mike Slippy

The first PCIe x1 slot I put it in caused my system not to boot. It's probably a motherboard issue, so I tried another free slot and it booted fine. However, this card was NOT driverless in Windows 10. I had to download and use the Windows 7 drivers as there are NO Windows 10 drivers available on their website (so confusing and annoying). But the Win7 drivers worked fine, but it took me a while to figure it out and a couple of reboots to get them working properly. Finding software on their website is neither easy nor intuitive. The printed instructions in the box aren't very good either. BUT once I was able to download and install the drivers and WebGUI I thought the setup process was pretty easy in the GUI and I LOVE the fact that when setting up the RAID1 on two drives that I previously had on the Intel RADI1 had, it didn't work. to DATA LOSS, which saved me hours of copying data from my backup. But make sure you back it up if you use hard drives with existing data. Time will tell how this RAID1 performs, hopefully the same as before with my Mobo Intel RAID setup.
