Are you ready? Let's read!

What is RAID 50?

This is a hybrid array, which includes two RAID 5 segments, which are combined into a RAID 0 array. Here, partial correction of the main disadvantage of RAID 5 occurs (low data writing speed), due to the parallel use of several such arrays. The total capacity of the array is reduced by the capacity of the two disks. RAID 50 can withstand the collapse of one drive per RAID 5 segment, and this despite the fact that you need six disks to create an array.

This type of array is most often used in complex applications and requires an expensive controller.

How does RAID 50 work?

Of course, the total capacity will be one diskless, but the performance and speed of rebuilding will be significantly higher. As mentioned above, RAID 50 can work with 6 or more disks (8 is ideal). In this case, all of these disks will be divided into 2 groups with a mechanism for arranging information, alternating with parity. The choice of this variant of the array is always conscious because the number of disks is considerable here.

But the controller is not very suitable, so get ready to pay a hefty sum for RAID 50.

What are the reasons for RAID 50 failure?

Initially, check to see if the spare disk is working or if the disk is out of order. It happens that this particular factor will be paramount.

Make sure that the PATA/SATA port, cables, and wires are in order (these connections may just be unreliable).

And so, you can do this in this situation: expand the array (make it grow), and then the RAID driver will look for a spare drive. This spare drive is a member of the array but is not active in it. Therefore, if you have a spare drive, you can increase the array by increasing the number of active disks for the array. For example, if you expect 3 disks and 2 to be active, you will need to increase the number of active counters to 3.

Driver RAID-array: This is detected and then finds a spare disk. Then it integrates it into the array as an active disk. Run it, and after synchronization, your array will have two active synchronized disks, but since there are no three disks, it will not be erased 100%. Delete the faulty drive, then resize the array.

RAID 50 data recovery with DiskInternals

DiskInternals RAID Recovery can create a disk image and restore your data! You will have a more than 90% chance of returning data of any type and format. This statement is based on 15 years of DiskInternals’ experience with information recovery. The source of array corruption and data loss does not matter; RAID Recovery supports both manual and automatic identification of important parameters, such as the type of RAID controller, the type of array, controller, file system, strip size, and disk order, etc. It will restore all files, where possible.

To illustrate the process, study this guide, and start downloading and installing the application to your laptop.

When opening the program, follow the instructions of the Recovery Wizard.

Then, in the new window, select the array that will be recovered.

Once the choice has been made, proceed with scanning (full or fast). This process is unlikely to be fast since arrays usually have a large capacity, and RAID Recovery inspects even the most remote places for deleted and inaccessible files.

You may preview the results for free, which is very helpful since you can check the integrity of the data.
