first mentioned is RAID... 0 I think, and the second one is RAID 1
but ahh, there are more than those two. There is also RAID 0+1, RAID 5, RAID 10 and so on. I would refrain from using RAID 1 as it is only for server use, and if you are going to use a server, might as well use RAID 5. RAID 0 is the most popular out of all RAIDs for the desktop as it is the fastest and gives the most performance. but there is always a point of dimishing returns
two raptor 150s in raid 0 might not always load faster than 1 74GB raptor. So RAID isnt always faster. Now, if you RAID 2 7200 RPM hard drives, then yes you will see a diference. Now, the catch with RAID 0 is that once one drive dies, it renders your other drive useless. And with RAID 0, you should get two of the same sized hard drives. like two 160GB hard drives are a nice combo. A good amount of space, while providing good performance.
