Hi,Im pretty much new to the whole computer thing, i mean i know the basic stuff, ive built a computer ot two. But sadly i dont know what raid is. I would really appreciate it if sombody could explain it to me and how to set it up? thanks alot.

Raid is pretty much putting 2+ hard drives together to form 1 whole partition. So, instead of having something like a C, D, and E hard drive, it can all be formed to become just C. There are various kinds of raid too...
JBOD = spanning the array, just adding them together, can work for various sizes.
Raid 0 = Having 2 of the same size drives together, apparently gives a performance increase, while decreasing the lifespan of your array. If one HD fails, the array fails.
Raid 1 = Redundancy, copies the same data over all of the hard drives in the array, needs the same size hard drive like 0.
Raid 0+1 = Requires 4 drives, creates 2 separate arrays, but the information is copied over both arrays.
Raid 5 = The newer thing, where it takes only 1 of your hard drives space, also has redundancy. So, you still gain space while having a lower risk of losing your information. Requires 3 drives.
Information about RAID is all over the net lol. You can add raid cards too if your motherboard doesn't support raid.

Raid 50 Raid 5'd Raid 0 arrays
Raid 6 like raid 5 but with two redundancies
Raid 2 Hamming Code, nice in theory, doesn't work in practice
Raid 3&4 Similar to Raid 5, but with different variations on the theme
Raid 10 Inverse of Raid 0+1, but better

That depends. Especially if you run applications with heavy loading times (like certain games), RAID 0 can certainly be worth it. I'm personally very pleased with my SATA/150 RAID0 setup. Of course it'll break sooner... but I think it's worth the very significant performance increase.
Statistically speaking, you would in RAID0 have 1/n times the lifespan of an individual device where n is the number of devices. Since in RAID0, all data will be lost if one drive crashes, there will be n times as many devices that can crash and the rate of failure will be twice as high. The wikipedia article on RAID offers more in-depth analysis.
it is if you are creating projects that you are planning to take outside of home, such as scripts or autocad layouts, I think RAID 1 would be ideal for this kind of work for any serious computer user.
Uh... what? What does whether you want to take your data 'outside of home' have to do with RAID1?
