How to Recover Data from a 4-Disk Raid 10 with Failed Controller
An old client recently brought me a Seagate BlackArmor NAS 400. with 4 disks. He configured it using RAID 10. The problem is that the controller has failed and is no longer under warranty. The Seagate support center informed him that if he replaced the controller with a new one, the drives would be formatted automatically as soon as he turned them on, and he would lose all of his data. I have no expertise in recovering data from RAID 10 NAS. Therefore I was hoping you might help... What methodology or software would be most appropriate for this without risking data loss?

Yes. You can recover lost data from RAID arrays even if the controller is failed because the status of the disks inside determines the operation of a RAID 10 array. If there are too many faulty sectors, the controller will detect the disk as defective or unable to assemble the array. It is also worth noting that because similar disks are typically used in the array, their lifespan is roughly the same. So you can recover data from broken RAID.
By striping RAID 1 segments, RAID 10 achieves extremely high I/O rates. This RAID mode is appropriate for mission-critical database management solutions that demand the highest performance and fault tolerance. A RAID 10 configuration yields half the total capacity of the array's devices.
RAID arrays stress the value of data because they were designed specifically to assure information safety in the event of physical disk failures. Nonetheless, losses do occur despite the high level of security. In certain circumstances, a disk failure is to blame, while user actions are to blame in others. Regardless of the cause, the user loses data that is critical to them. As a result, if your RAID 10 fails, you should immediately begin RAID recovery from the disks and attempt to restore the array.
RAID data recovery is indeed tough if the standard method is used. You should remove the disk, rebuild the RAID, and then connect to your PC to restore data. The best thing to do is immediately use EaseUS Data Recovery Wizard, professional software for recovering lost data. You do not need to remove the disk and recreate the RAID. All you have to do is utilize EaseUS data recovery software. Launch and use this software. The software will then scan your NAS server.
As you can see, the RAID 10 data recovery process is straightforward. It does not necessitate any PC knowledge, making the EaseUS Data Recovery Wizard ideal for both pros and inexperienced users.
