Hi I am a noob when it comes to RAID configs, I have only ran a couple RAID 0 configs a while back but as it stands right now I want to RAID 0 x2 WD 750GB blacks and mirror all that data to a third larger drive like a 2TB WD black... what type of RAID would I require for this?

The bottom line is that I want the fastest configuration with a complete backup to a larger drive...

Here is my other post on the 24GB workstation I am building for design/modeling, thanks!

This will most likely be the motherboard used...

from the few minutes of research I have read will it sounds like I am describing RAID 10...so I will need a minimum of four drives? I read it from here..

If you want to have a true RAID 10, then yes you will need to have 4 drives to complete the configuration.
Not sure which Windows version you are using, but you can also do what you want within Windows by upgrading the disks to Dynamic disks and configure your RAID there. The Windows RAID system will operate at the volume level instead of the drive level, allowing you to mirror your current RAID 0 to a large enough partition on your 2TB drive.

raid 5 is what you are seeking it uses three drives one giant for backup and two for performance

this raid 5 does it still offer the same high performance as the raid 0. that just has the back up drive or having the back up drive slow it down a little?

yeah its exactly like combining raid 0 and raid 1 the raid 0 using the two drives for performance and the raid 1 for backing up data

What? That youtube link isn't explaining it properly.

All drives are used concurrently, not two used as a stripe and the third as backup. He makes it sound as though the third is a dedicated mirror, which is inaccurate. See this...

http://en.wikipedia.org/wiki/RAID_5#RAID_5

You need a minimum of three drives for a RAID 5. The main advantage being (for the normal user) is that if any one drive dies, you can still rebuild your array with a minimal risk of data loss. The performance is also much better than a mirrored array.
