What Is Raid and Its Types?

RAID (Redundant Array of Independent Disk) is a way to store a specific data in different places on different hard disks, solid-state drives simply to protect the data if in case a hard drive failure occurs. RAID is mostly related to those set of components in our computer that allows us to store information and let the computer run in a systematic condition. Developers have designed and updated RAID for us to experience improved redundancy and performance of the storage system of computers.

How does it work?

RAID is not too complex to handle, it works simply by placing all the data on different disks, and then allowing I/O operation to overlap seamlessly, this is how the performance is improved. As the use of multiple disks rises, the chances of failure of the disks after storing the data also increase with an increase in fault tolerance. It acts as a single logical drive in the operating system and also inculcates a definite technique to handle your data which is disk mirroring and striping.

Mirroring is when it copies identical data on more than one drive for safety and security. Whereas, when we talk about striping, it is the partition that helps the data to be spread over different disk drives. The drive's storage space gets divided into a small unit that ranges differently, at the time a sector or several megabytes. Disk mirroring and stripping can be combined as well in the RAID array.

The various benefits of RAID configuration.

RAID configuration is a combination of various effects. One on hand you get to have several hard disks combined that increase the volume of storing the data. On the other hand, this allows the best benefit of disk facilitating data retention for a longer period including fault tolerance about data duplication. It became pretty easy to use the RAID configuration of the varied server to maintain the information even if one of the drives gets break down or failed.

Not just that, you can also use the RAID configuration to increase the performance and speed of your hard disks. One thing to bear in mind is, there is not merely one specific type of RAID available, but many and all depends upon the benefits you want to seek from it and make use of for your storage.

The different types of RAID:

The benefits of RAID configuration have a lot to do with the type of configuration in RAID that you choose. The most common and popular ones are discussed here:

RAID 0: It is also said to be striping is completely different from others and it does not seek data redundancy but it rather is used to pass on information through varied hard disks. This type of configuration solely aims at achieving good speed. You don’t keep any extra form of data, this means when the fault or breakdown occurs, loss of information seems to become a big challenge.

RAID 1: It is called mirroring and by the name suggests that it mirrors the hard disk or copy it to another. It is greatly helpful in case of data loss as if one hard drive fails the other copied ones have all the information stored. The main purpose of it is data integrity and guaranteed solution for data loss problem.

RAID 5: It is pretty complex and is distributed by parity. In this type of configuration, the information gets divided and also duplicated like RAID 1. So, you can expect dual benefit, one is the higher speed and the second is data duplication.

RAID 10: RAID also known as RAID 10 is when each disk is mirrored that is working in stripping. It is a commonly found and used data configuration type and its fault tolerance are pretty amazing. It is a widely accepted and most used database server and people opt for it, because of the greater performance, speed, and professional opportunities that are delivered.

“Data Recovery Software Free Vs Paid”

Data loss pretty much is the biggest nightmare for any business owner and it can happen for a wide variety of reasons including accidental deletion, virus, malicious attack, and so on. That is why many business owners think working with a recovery plan which is a smart idea.

They try to opt for the cheapest possible ways like free data recovery software that can help them recover all the lost data. But the question here is, can data be fully recovered from a free recover tool or a paid one? As not all businesses can afford expensive data recovery software, the question to opt for a free version that might help them make informed decisions.

Although one might get a sophisticated tool to recover data from a free tool, people don’t know how to perform the recovery from the software. The only difference between paid and non-paid is the type of media that supports the size of the recovery.

If you wish to recover larger files the possibility of getting recovery though a free version doesn’t seem to be a solution. There are many tops and branded data recovery tools that are used and can enable you to perform the scanning and recovering in no time.
