RAID 1 Disk Mirroring Benefits For Improved Data Storage Systems

raid-1-pros-and-consds

RAID stands for Redundant Array of Independent Disks. This is a form of data storage that combines virtualization and physical disk drives into a single unit. RAID storage is often used to keep copies of important data and improve computer performance. There are several levels of this storage, just as their are several Akamai class levels. RAID 1 is a popular data storage level. However, it does have some drawbacks. Below is a complete overview of RAID 1 and the possible advantages and disadvantages it could bring to your company’s data storage system.

AKA Disk Mirroring

RAID 1 is also known as disk mirroring. The disk mirroring process is the act of replicating data to two or more disks. This storage tactic is a great option for applications requiring both high performance and high availability. Some examples of this would be transactional applications, email and various operating systems. This is just one of the many ways that technology grows business. If you are considering RAID 1 data storage or disk mirroring, find out its advantages and disadvantages below.

RAID Levels

It is important to note that RAID 1 is just one of several RAID levels. There are twelve total RAID levels. However, there are just 5 primary ones. The others are variations of the main RAID configurations. These main RAID configurations include RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10. Then there are the similar configurations RAID 2, 3, 4, 7, 8, 9 and RAID 0+1. Keep this in mind when considering the advantages of RAID 1 storage.

Pro: Data Protection

Among the RAID levels of data storage, RAID 1 is the one focused on disk mirroring. With RAID 1, important data is duplicated onto separate drives. Unlike RAID 0 which specializes in data stripping across multiple drives, RAID 1 will always have a complete copy of your data available should any drive fail, similar to HPUX. This is because each drive has an identical twin, so to speak. The exact copies of every file you have are stored on an extra drive. If you want to use a data storage method that will keep you from losing important information, go for RAID 1.

Con: Cost

Although RAID 1 excels in data protection, it also exceeds other data storage forms in price. RAID 1 requires two complete drives for one set of data. Everything from one drive will be copied onto another, which cuts your storage space for any lossless file in half. You will end up buying twice as many drives for the same amount of storage space. If you have a lot of data or a lot of drives already, this could become a very costly form of data storage. Only use the RAID 1 method if you are willing to pay the price.

Pro: Simplicity

Although it can be expensive, RAID 1 offers the great benefit of simplicity. By having duplicates of all of your data on separate drives, you know exactly what and where you can access certain information. RAID 0, on the other hand, strips data and rewrites it onto multiple disk drives to be safe. This can cause trouble when one of your main drives fail and you are scouring through the rest to find the information you need. With RAID 1 you can enjoy the simplicity of readily available data as if your original hard drive never even failed in the first place!

Con: Speed

RAID 1 may help to improve your computer’s storage and performance, but it can also cause some lag when writing data. It is not quite as swift as Hyundai cars. While its read speeds are comparable to RAID 0, RAID 1 stores identical copies of data on different drives. This means that, when you are saving new data, the operation may take more time. RAID writes the data twice. This simultaneous action can put a strain on your system.

RAID 1 is an excellent storage option. It can save all of your information onto a separate drive, and bring you peace of mind knowing that your data is backed up, unlike your VoIP server. If you enjoy the pros of a data mirroring storage method, RAID 1 is definitely for you.
