This question was answered on March 10, 2003. Much of the information contained herein may have changed since posting.RAID protects your data in the unlikely event of a drive failure If a disk drive fails in a RAID system, network clients are unaware of the incident and they continue on with their work as if nothing happened The RAID system continues to perform read/write operations and if a hot spare is available then it automatically becomes part of the array and data that was on the failed drive is automatically regenerated onto this new drive in the array.
RAID Level 0 is the fastest and most cost-effective array type but provides no data protection Reliability is actually less than that of a single disk drive
RAID Level 1 and 0 1 are good choices in environments where performance and data protection are more important than cost.
RAID technology stripes data across multiple disk drives to create one or multiple large logical drives.
Striping is the foundation of RAID Disk drives in a RAID group are partitioned into stripes, which may be as small as one sector or as large as several megabytes The stripes are interleaved so that disk space is composed of alternate stripes of each drive Data is written across the stripes instead of onto a single drive The sizes of the stripes vary depending upon the application I/O intensive applications benefit from large stripe sizes and data intensive benefit from small stripe sizes
