Biostar A58M Owner's Manual

RAID 10 combines the advantages 
(and disadvantages) of RAID 0 and 
RAID 1 in one single system. It 
provides security by mirroring all data 
on a secondary set of disks (disk 3 and 
4 in the drawing below) while using 
striping across each set of disks to 
speed up data transfers. 

­ 

Drives: Minimum 4, and maximum is 6 or 8, depending on the platform. 

­ 

Benefits: Optimizes for both fault tolerance and performance, allowing for automatic 
redundancy. May be simultaneously used with other RAID levels in an array, and 
allows for spare disks. 

­ 

Drawbacks: Requires twice the available disk space for data redundancy, the same 
as RAID level 1. 

­ 

Fault Tolerance: Yes. 

 

A RAID 5 array can withstand a single 
disk failure without losing data or 
access to data. Although RAID 5 can 
be achieved in software, a hardware 
controller is recommended. Often extra 
cache memory is used on these 
controllers to improve the write 
performance. 

­ 

Drives: Minimum 3. 

­ 

Uses: RAID 5 is recommended for transaction processing and general purpose 
service. 

­ 

Benefits: An ideal combination of good performance, good fault tolerance, and high 
capacity and storage efficiency. 

­ 

Drawbacks: Individual block data transfer rate same as a single disk. Write 
performance can be CPU intensive.

 

­ 

Fault Tolerance: Yes.

 

Note: The RAID 5 function is only supported by A88X chip set.
