RAID 0

The easy way to remember RAID 0 is to zero out the capital R, which leaves AID. And that is exactly what this standard is, an AID.

RAID 0

RAID 0 offers no protection (redundancy) against drive failure.


RAID 0 is also called Disk Striping with No Parity. The idea is to take a file, and distribute the data so different hunks “o” data are written to two or more drives.

Figure 57: RAID 0 - Disk Striping.

 

Since a hard drive is the slowest part of a computer, in either reading or writing data, it is faster than a single drive. And if any one of the drives fails, all the data is gone.

And for say, a web site that has static data with thousands of folks hitting the same data, this isn’t such a bad idea to make a RAID 0 drive array. If it dies, yank the drive and restore the files.

Further good news is every byte of drive you bought is usable. Buy two 9 Gig drives; you have 18 Gigs of storage.
