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

So I went out and bought one because I was having trouble setting up RAID on my motherboard using my own methods. After some research I've come to the conclusion that a RAID controller in a PCIE slot (PCIE x1 FYI) will handle the RAID and avoid the required system overhead. The device is quite easy to install. Simply find a free PCIE slot, slide out the grille covering the slot on the back of the PC case and slide it into the slot. The unit came with SATA cables (I believe they are SATA III but I use my own which are definitely SATA III) and a low profile connector if required. After installing the hardware, start your computer and navigate. on the HighPoint website. You need to download two items to set up the RAID. To make your search easier, I'd recommend searching Google for the relevant page on the HighPoint website - it's not very intuitive, but Google's search bots didn't find any problems for you. So download BOTH the drivers for the card and the WebGUI. Then unpack both folders and install WebGUI. For RAID drivers you need to go to Device Manager, find it in the list of items (it will likely have a yellow exclamation mark on its icon) and then right click > Update driver. From there you have to manually search for drivers on your computer. Navigate to the folder you just extracted for the drivers and select the folder that matches your system (32 or 64 bit). The utility completes the controller and mounts it successfully. Then restart your computer to allow the computer to properly initialize the controller. Now we can finally start using the equipment. Launch the WebGUI and navigate through the utility. Make sure the controller recognizes the drives correctly and go to the "Array" tab on the left. From here you can run a simple utility that will create the RAID you want. Finally, once you have your RAID set up, open Windows Explorer (as if you were opening a file anywhere on your computer) and right click on your computer. , and then click Manage. From here, select Disk Management under Storage. You should see a new drive of the same size that you installed during RAID Utility, and it should also have a black (not dark blue) stripe at the top. Right-click, select "New Simple Volume" and follow the installation wizard to create a new disk. Once you've set up the drive, you're done and ready to use it like any other drive. Congratulations! You now have an active RAID array on your PC.
