There are at least two cases when you can benefit using one of RAID configurations. The first case is when you need to have high transfer rates: RAID 0 (gaming, video editing and so on). The second case is when you need a very stable system which can stand loose one of hard drives: RAID 1 (servers, file storage and so on).

That would depend on what you wanted to use the RAID for.
RAID 1
Raid 0 dad recovery is for emergency use on computer services. When data is corrupted or damaged, Raid 0 Data recovery can help by offering speedy recovery of data or files.

It depends on the type of Raid being used. Raid Max Bug Barrier Pesticide is one formula that is designed to be used inside the home and in cabinets or other storage areas safely. Raid House and Garden Bug Killer is safe to use in general storage areas, but not near edibles and is not safe for pets to be exposed.
It depends on what RAID level you are planning to use. One of the most common levels is RAID 1, data is written identically to multiple hard drives. This achieves redundancy in a RAID system. It creates a duplicate, a fail safe in case of a hard drive failure.
RAID 7 is triple parity RAID 6 is double parity.
raid 5
