RAID 6 peculiarities

To implement this array, at least four disks are required. But how many drives can fail in RAID 6?

The number of disks that can fail in the RAID is equal to two (which is unlikely in practice, but if this happened to you, then you are "lucky"). As a result, fault tolerance here is much higher than that of other types of arrays. In addition, the read speed here is at a high level, since data streams from several disks in the array are processed in parallel.

It should be understood that a decent amount of money should be paid for a reliable and efficient array. However, if you are interested in this, then RAID 6 will not let you down.

You should keep it in mind!

The axiom is that all disks in an array are equal. So if two disks are dead, then the rest are in danger. And before you start replacing failed disks, you need to take care of your data. The backup process is usually quite lengthy. A simpler solution is a disk image. A disk image can help in data recovery, as it contains all the information from the disk and all installed configurations at the time of creating the disk image.

DiskInternals RAID Recovery will help you create a disk image for free, and it does not require any skills or knowledge. You don’t even need the help of the Recovery Wizard since the process of creating a disk image using DI RAID Recovery is quite simple. Thus, you will have a duplicate of your hard drive, which will protect you from the inevitable loss of any data, OS parameters, etc.

How to replace two dead drives in RAID 6

Is it worth replacing two dead drives simultaneously or one at a time?

  1. If you replace two disks at once, there is a nuance: RAID 6 is rather slow in terms of its integrity. This means that the remaining disks will buzz for a very long time, with a high probability of death without assembling the array. Therefore, this option is not very attractive.
  1. If you change the faulty disks one by one - this is the best solution because of the recalculation RAID 6.

If RAID6 is in the wrong condition - use RAID Recovery

DiskInternals RAID Recovery helps you build an array and recover the missing information.

This application is leading at the current level since it has been improved by leading IT-specialists and keeps up to date for the past 15 years. As mentioned above, the application has the popular function of creating a disk image, and also well restores all levels of arrays without exception. The application automatically detects the type of source RAID while also providing fully manual operation. This is especially convenient since you can monitor and control the recovery process.

Previewing at no cost is a great bonus and an addition to the main functions of the application. Buying a license is not required here, but if you want to export the recovered data, then the license is required.

Recovery algorithm using this product:

Install the DiskInternals RAID Recovery software on the computer.

Open the application and launch the Recovery Wizard. Attach each RAID disk individually to the computer.

The program automatically determines available arrays - select the one you need.

Next, select the recovery mode. In this case, Uneraser or Reader is preferable.

After scanning, view the results for free and then complete the entire process by exporting data. Remember, you need a license for this.

Follow these recommendations, and you will succeed. Good luck!
