![]() ![]() Replacing a disk in an array, recreating instead of rebuilding, connecting disks in the wrong order – all of these errors can lead to a guaranteed failure. RAID can fail not only due to software or hardware failures, it can also occur due to human error. Consequences can range from a startup error to complete loss of stored information. Any incorrect driver or OS update can cause an array to fail irreparably. Software RAID arrays created within Windows, MacOS, Linux, Ubuntu and FreeBSD are directly dependent on the performance of the operating system. It can only be restored by recreating it. Its failure, BIOS firmware update, power surge or wrong connection of the disks – all these can cause damage to the array. If the user can not buy a hardware controller, he creates a software controller, directly on the motherboard. If the controller gets damaged, the array fails. This helps improve fault tolerance and performance. A RAID controller is a virtualization technology that combines several physical disks into one logical module. If the controller is damaged, it needs to be replaced immediately. If you damage the engine in a car, it won’t go anywhere. ![]() Therefore, disk corruption is the leading cause of all array failures. ![]() For most RAID arrays, the loss of even a single disk can be fatal – one failure and all devices fail like a chain reaction. Of course, for server disks like NAS or SCSI, this lifespan is much higher, but let’s not forget that nothing in this world lasts forever. Hard disks and SSDs cannot last forever, they both have a very limited lifespan, which over time risks being used up. It must be preceded by a number of possible causes. In addition, the application is also compatible with software controllers such as Storage Spaces. In addition to the basic purposes, Starus RAID Restore supports single-drive volumes and JBOD composite arrays. Starus RAID Restore supports all popular controller types and works with the following types of arrays: ![]()
