In summary, RAID levels play a pivotal role in the design and implementation of a RAID system. By understanding the characteristics and capabilities of different RAID levels, system architects and administrators can tailor RAID systems to meet specific performance, fault tolerance, and data protection requirements.
Disk Capacity
Disk capacity refers to the amount of data that can be stored on a physical disk drive. In the context of a guide to setting up a RAID system on your PC, disk capacity plays a crucial role in determining the overall storage capacity and performance of the system.
-
Total Capacity
The total capacity of a RAID system is the sum of the capacities of all the individual disks in the array. RAID systems can be configured to increase the total capacity beyond the capacity of a single disk, providing a scalable storage solution.
-
Usable Capacity
The usable capacity of a RAID system is the amount of storage space that is available for data storage after accounting for redundancy and parity information. RAID levels that implement redundancy, such as RAID 1 and RAID 5, have a lower usable capacity compared to RAID 0.
-
Disk Size
The physical size of the disks used in a RAID system can impact the overall capacity and performance. Larger disks typically have higher capacities and can improve performance by reducing seek times.
-
Expansion
RAID systems can be expanded by adding additional disks to the array. This allows for increased storage capacity and performance, but it is important to consider the compatibility and limitations of the RAID controller and disks.
Understanding disk capacity is essential for designing and implementing a RAID system that meets specific storage requirements.

Fault Tolerance
Fault tolerance is a critical component of a guide to setting up a RAID system on your PC. It refers to the ability of a system to withstand and recover from hardware failures without losing data. RAID systems achieve fault tolerance by distributing data across multiple disks, so that if one disk fails, the data can still be accessed from the other disks.
There are different levels of fault tolerance, depending on the RAID level implemented. For example, RAID 1 (mirroring) provides the highest level of fault tolerance by duplicating data on two or more disks. RAID 5 (striping with parity) provides a lower level of fault tolerance by distributing data across multiple disks and using parity to reconstruct data in the event of a disk failure.
Fault tolerance is essential for any system that stores critical data. By implementing a RAID system with an appropriate fault tolerance level, system administrators can protect data from hardware failures and ensure the availability and integrity of their data.
Data Redundancy
Data redundancy plays a critical role in a guide to setting up a RAID system on your PC. It refers to the practice of storing multiple copies of data to protect against data loss or corruption. RAID systems utilize data redundancy to ensure that data remains accessible even in the event of a hardware failure.
Data redundancy is a critical component of a RAID system because it provides fault tolerance. By storing multiple copies of data across multiple disks, RAID systems can withstand the failure of one or more disks without losing data. This makes RAID systems ideal for storing critical data that cannot afford to be lost.
