RAID Level 3 technology use a dedicated parity disk to store
redundant information about the data on several data disks. RAID
Level 3 is an excellent choice for applications which require single
stream I/O with a high data transfer rate.
RAID Level 3 is optimal for applications in which large block of
sequential data must be transferred quickly, these applications are
usually of one of these types :
They operate on large data objects such as graphical image
processing, CAD/CAM files, and others.
They are non-interactive applications that process large data
sequentially.
They usually request a large amount of data (32KBytes or more)
with each I/O request.
The distinctive performance characteristics of RAID Level 3 :
RAID Level 3 provides excellent performance for data
transfer-intensive applications.
RAID level 3 is not well suited for transaction processing or
other I/O request-intensive applications.
