Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Thecus also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

New Security Features: Updates may introduce new security features or enhancements that can further protect the NAS device and the data stored on it. These features may include improved encryption algorithms, stronger access controls, or additional security protocols.
Compatibility with New Devices and Technologies: Updates and patches often ensure compatibility with new devices, technologies, or software versions. This ensures that your NAS device can work seamlessly with the latest hardware and software, reducing any potential vulnerabilities that may arise from outdated or incompatible components.
Protection against Emerging Threats: Regular updates help protect against emerging threats and malware. As new vulnerabilities and attack vectors are discovered, software updates often include patches that address these new threats, providing an additional layer of protection for your NAS device.
Compliance with Industry Standards: Many industries have specific security and compliance requirements. Regular software updates and patches help ensure that your NAS device remains compliant with these standards, reducing the risk of penalties or legal issues.
