Find out the benefits of RAID arrays

Here you will find out:

  • what are the benefits of the different RAID
  • what are the difference in various RAID arrays

Are you ready? Let's read!

What is the purpose of RAID?

RAID is a complex of several hard drives (SSDs are increasingly being used lately).

This array is used to increase the reliability of data storage. And also to increase the speed of reading/writing information. There are different types of these configurations and are marked with different numbers: 1, 2, 5, 0, etc. Accordingly, each of these array options has different functions in priority. RAIDs are significantly more convenient and efficient than using a single disk in the system, so they are widely used not only in the manufacturing sector, but also by individual users.

Advantages of RAID in different levels

Let's analyze the most common arrays and the main advantages of RAID:

  • RAID 0 - an array using 2 to 4 disks (more is possible, but rarely used). The data distribution mechanism is based on interleaving, so the disk capacity is fully utilized. However, as a result of this, the array does not have redundancy. If even one disk is damaged, you will lose all information - fault tolerance is lame here. The main advantages of RAID are to improve performance. Therefore, if recording speed is important to you, select this array and do not forget to backup the data more often.
  • RAID 1 - In contrast to RAID 0, the distribution of information according to the type of mirroring is used here. It turns out that you kind of “lose” the volume of the second hard disk (it is used to write a full (byte to byte) copy of the first hard disk onto it). The advantage of RAID is that it has high reliability - it allows you to fail an entire disk without losing data. Replacing a damaged disk is possible only after turning off the computer; therefore, if it is a server with many computers, this is not very convenient.
  • RAID 5 - It is very similar in principle to working with RAID 1. Only that you need at least three drives, one of which will store the duplicated information. In this case, almost the entire volume in the system will be available to you, except for one data disk for recovery. Recovery, in turn, can drag on for a very long time. In addition, productivity will increase, but slightly. This type of array is quite expensive.
  • RAID 6 is an expansion of RAID 5. When using this technology, even a failure of two hard drives in one group at once will not lead to data loss. Recovery time also increases due to the complex mechanism of work. Reading procedures are fast, and writing is a bit slower.
  • RAID 10 (1 + 0) - you should immediately understand that this array will be expensive. There is a symbiosis of mirror reflection and alternation, which in turn contributes to the security of this array and high performance.
  • RAID 50 (5 + 0) - it is clear that this is a combination of arrays 5 and 0. It contributes to the high speed of data transfer, as well as query processing and good speed. The only thing that is required is at least six disks, and this will also be costly.
  • RAID 60 (6 + 0) - here you already need eight or more disks. But, in return, you will get good failure resistance and fairly fast data transfer - the main advantages of RAID 60 (6 + 0).

RAID data recovery difference

The choice of the desired application depends on the number of disks and the type of RAID.

For RAID 1 recovery can be used RAID Recovery, but depending on the file system, it is also applicable to DiskInternals Uneraser, DiskInternals Linux Recovery, or Partition Recovery. In other cases, it is better to choose DiskInternals RAID Recovery.

It should be noted that RAID 0 recovery is pretty much difficult, but it is worth to try DiskInternals RAID Recovery for this purpose.

DiskInternals RAID Recovery uses innovative algorithms that allow you to recover your files, such as multimedia files and documents. The application restores the array from the available hard disks, and the necessary type and size of disks are automatically determined, as well as the order of the disks. No special technical skills and knowledge are required to use the program. You can store files on another hard drive or partition, use virtual disks, or even upload files via FTP.

Use the algorithm and the recovery process will even become easier:

  1. 1. Download, install, and open the DiskInternals RAID Recovery application.
  1. 2. The recovery wizard will prompt you to take the first steps:
  • select the desired RAID array
  • select the desired software mode (fast or full scan).
  1. 3. Wait until the scan is complete and start the preview of found files (for free).
  1. 4. Purchase a license and complete the export of data to another storage device.
