Is RAID necessary?

RAID 0:
RAID level 0 refers to striping data across multiple disks without any redundant information.
Striping can be used to enhance performance in either a request rate intensive or transfer rate intensive environment. Unfortunately. Striping reduces the level of data availability since a disk failure will cause the entire array to be inaccessible.

What are the chances disk will fail? (i will have HD cooling) Will it dramatically speed up transfer/request rate? ie. 2 x 10,000RPM HD = 20,000 RPM?

RAID 1:
RAID level 1 refers to maintaining duplicate sets of all data on separate disk drives. Of the RAID levels, level 1 provides the highest data availability since two complete copies of all information are maintained. If one of your hard drives fail, you will have an exact copy of all your data on your other hard drive, meaning that you can carry on working as normal without having to restore lost files. You could see it as having a permanent automatic back-up of all your data. Even if one hard drive fails, you can then use the other hard drive to create a new RAID array and so in theory (unless you have an electrical surge, or both hard drives fail simultaneously) you can never be caught out when you turn on your computer one day to find that your hard drive has failed, because you always have a backup.

Will RAID 1 be equal/faster/slower performance than RAID 0?
Is RAID 1 just for people who are cautiuos about data?

All i am after is fast transfer/request rates.
Also, is RAID relatively hard to set-up?
Thanks (too many questions lol)
