This can be

driving them behaves. The minimum is two physical drives (see Figure 10-3); the more
drives you add to the RAID 0 array, the faster the disks will behave. This implementation
is all about performance. While RAID 0 can be blazingly fast, if a single drive in the array
fails, all data will be lost. In disaster recovery, RAID 0 is the ???RAID that shall not be
named??? of disk configurations. Avoid it.
Figure 10-3. RAID 0 at work. This setup offers no protection and no redundancy??”just speed.
RAID 0 is rarely used in business environments, but when I do see it, I always ask as
many people as possible, ???So, it??™s no big deal if you lose all of the data on your S: drive,
huh???? This usually causes panic and lots of screaming, often accompanied by an angry
mob carrying torches and pitchforks and storming the IT offices.
Personally, I use RAID 0, deliberately and with excellent results, in my personal gaming
PC, which is built for speed??”no data protection required.
