Basic information about RAID configuration

Here you will find out:

  • what is RAID configuration
  • which RAID configuration is better
  • when DiskInternals can help you

Are you ready? Let's read!

RAID and its benefits

By using RAID, you improve performance primarily because data is spread across multiple disks and I/O operations overlap in a balanced manner.

Another important benefit of the array is good fault tolerance since the use of multiple disks increases the mean time between failures. These benefits can vary to a greater or lesser extent depending on the level of your array. And of course, using the array expands the possibilities for storing your data. However, do not confuse data storage in a RAID with backup. This is not an alternative to a backup at all since the array in some cases can be damaged or deleted without damaging the disk on which it is stored.

RAID configuration

The following are the basic parameters for creating a RAID:

  1. 1. The array requires 4 disks for optimal performance.
  1. 2. IDE, SCSI, or mixed architecture is required.
  1. 3. Each disk in the array must be dynamic. If you have a basic disk, you can easily convert it to being dynamic without any data loss. However, they must contain at least 1 MB of free space at the end of the disk for a successful upgrade.
  1. 4. All system files and the boot operating system must be on a different volume.
  1. 5. All dynamic disks must be mounted when the volume is created.
  1. 6. Depending on the choice of the array level, there are several mechanisms for distributing information:
  • Striping - example - RAID 0.
  • Mirroring - example - RAID 1.
  • Parity - example - RAID 5 (striping with parity technique).

Which RAID configuration is better?

The first question to ask is, what type of RAID are you preparing: hardware or software?

In hardware RAID, drives are connected to a RAID controller card inserted into the server's motherboard for optimal performance. It also provides a lot of functionality due to the variety of configuration options. This gives you more freedom. But the cost of such an array will be considerable.

Software RAID is a more budget-friendly option; the drives are connected to the server motherboard without a RAID controller. As a result, there are many restrictions according to the array level.

The second question is, how many disks do you have? Based on this, choose the best configuration for you.

If you install RAID on your computer and lose data

If you have lost some or all of the data from the array, do not hesitate. You will need an array recovery application as soon as possible. And not just any application: one that is professional-quality and will not permanently damage the array.

The best option is DiskInternals RAID Recovery. With this application, each stage of data recovery is automated as much as possible. You don't need to worry about your skills, as the Recovery Wizard will accompany you until the end of the data export. A free preview of files should be pleasing to you.

Also, read the instructions:

Download RAID Recovery to your computer or server and then install the software on Windows 7, 8, 10, Vista, or Windows Server 2003-2019.

Open the app (you can activate the Recovery Wizard) and then be sure to select the target RAID.

Then select the array scan mode in which you will be working:

  • Fast recovery mode
  • Full search mode
  • Reader mode

After that, you will have access to files in read-only mode for free.

Then buy a license for RAID Recovery. You now have unlimited access to your files and the ability to export selected files to any device.
