RAID 0 is, in theory, faster at retrieving information. However, you need to determine how much speed you need, and understand the risks involved.
1) how much speed do you need? If you are looking for fast data retrieval (this is most important in a server as this is a server's function) then a RAID array that uses some form of striping would be wanted. This could mean RAID 0 or RAID 5 (the most common server configuration). But in your case, what are we comparing the speed to? A parallel hard drive? Then go to SATA 1.5, as that will be faster. You need/want more speed? Then go to SATA 3.0. Get a hard drive with the largest cache. This will give you the best data retrieval speeds, and are just fine for most personal, and most business needs as well - no RAID needed.
2)the dangers of striping: What if one of your hard drive fails? You will end up with one good hard drive with a bunch of useless 1/2 information on it. In effect, you will have lost everything! If you plan on using RAID 0, have a good backup/disaster recovery plan.
Or, what if your hard drives are fine, but your mobo fails next year. A direct replacement mobo cannot be found as they are no longer available for sale. How are you going to recover your data?
These are the danger issues with using striping.
As far as explaining the various types of RAID and their advantages/disadvantages at large, I don't think using this site and the helpers because you are lazy is the way to go. I don't think you will find a lot of support for that. However, just by Googling what is RAID you will find a wealth of info that I suggest you read over.
Again for most home users, RAID 0 or RAID 1 or RAID 10 are the best choices, and in some cases the only choices as that is all the mobos will support.
