Understanding What A RAID System Is

Business owners, artists, writers, and students need to find effective ways of backing up their computer data so that it will be safe and secure no matter what happens to their main computers and other devices on which they work. Precious photos, videos, musings, and work-related documents are stored on everyone’s computer, and when this data is lost, it is absolutely devastating. The only way to prevent these losses from occurring is to back up all of the data properly. And a RAID system could be the perfect solution.

Many people have heard of RAID systems but they are not sure what exactly they are or how they operate. If you are one of these people, continue reading for a basic explanation and breakdown of what a RAID is and does.

What Is a RAID and What’s So Great About It?

RAID stands for “redundant array of independent disks.” These types of drives serve a variety of purposes. For individuals who save a lot of large files on their computers, such as photos and videos, a RAID system is great because it can store all of that data that would otherwise be taking up valuable hard drive space on the computers themselves. This can maintain peak computer performance.

RAID systems are also very popular for those who are seeking a great way to back up their data. The multiple disks in a RAID system provide multiple copies of all of the data that is saved. If one disk fails and needs to be replaced because of age or damage, there are other disks with the same exact data on them to ensure that nothing is lost.

Levels of RAIDs

Different levels of RAIDs have been established in order to clarify their performance abilities and capacities. In total, there are about 12 different levels, but below is a breakdown of just some of the most popular types available.

A Level 0 only backs up the data once, so it is really only suited for those who want to get a lot of data off of their hard drives to improve computer performance. For those who are looking for a secure backup system, this would not be appropriate because if it fails, all the data is lost.

A Level 1 RAID must have a minimum of two disks in order to properly copy the data off one disk onto the other to provide redundancy.

Level 5 RAIDS are more complex. This level holds at least three disks in place. It is quite possibly the most popular RAID configuration, especially for systems with multiple users. It will not only serve as a great backup plan, but it will also help maintain your computer’s performance by opening up drive space.

Implementing a RAID system in your home office or at your business can be a worthwhile investment. It really is one of the very best ways to secure your data and make sure that you will have redundant copies of it in the event of a crash.
