Appendix C: RAID Basics 

Overview 

A Redundant Array of Independent Disks (RAID) is an array of several hard disks 
that provide data security and high performance. A RAID system accesses several 

hard disks simultaneously, which improves I/O performance over a single hard 
disk. Data security is enhanced by a RAID, since data loss due to a hard disk 

failure is minimized by regenerating redundant data from the other RAID hard 
disks. 

 

Benefits 

RAID improves I/O performance, and increases data security through fault 
tolerance and redundant data storage. 

Improved Performance 

RAID provides access to several hard disk drives simultaneously, which greatly 
increases I/O performance. 

Data Security 

Hard disk drive failure unfortunately is a common occurrence. A RAID helps 
prevent against the loss of data due to hard disk failure. A RAID offers additional 

hard disk drives that can avert data loss from a hard disk drive failure. If a hard 
drive fails, the RAID volume can regenerate data from the data and parity stored 
on its other hard disk drives. 

 

RAID Levels 

The Thecus 1U4500 supports standard RAID levels 0, 1, 5, 6, 10, and JBOD. You 
choose a RAID level when you create a system volume. The factors for selecting a 

RAID level are: 
 

 

Your requirements for performance 

 

Your need for data security 

 

Number of hard disk drives in the system, capacity of hard disk drives in 
the system 

 
The following is a description of each RAID level: 

RAID 0 

RAID 0 is best suited for applications that need high bandwidth but do not require 

a high level of data security. The RAID 0 level provides the best performance of 
all the RAID levels, but it does not provide data redundancy.  

 
RAID 0 uses disk striping and breaking up data into blocks to write across all hard 

drives in the volume. The system can then use multiple hard drives for faster 
read and write. The stripe size parameter that was set when the RAID was 

created determines the size of each block. No parity calculations complicate the 
write operation.
