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 Asustor also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can storage tiering or caching strategies impact data availability and potential loss on NAS Asustor LOCKERSTOR 2 Gen2 devices?

Storage tiering and caching strategies can have a significant impact on data availability and potential loss on NAS Asustor LOCKERSTOR 2 Gen2 devices. Here's how:

Increased Data Availability: Storage tiering and caching strategies can improve data availability by ensuring that frequently accessed or critical data is stored on faster storage tiers or cache. This allows for quicker access to data, reducing latency and improving overall system performance. By prioritizing data based on its importance and access patterns, the chances of data being available when needed are significantly increased.
Reduced Potential Data Loss: By implementing storage tiering and caching strategies, the risk of data loss can be minimized. These strategies often involve redundancy mechanisms such as data mirroring or RAID configurations. In case of a drive failure, the redundant copies of data can be used to rebuild the lost data, ensuring that no data is permanently lost. Additionally, caching strategies can also help mitigate potential data loss by temporarily storing frequently accessed data in cache, reducing the reliance on slower storage devices.
Improved Disaster Recovery: Storage tiering and caching strategies can also play a crucial role in disaster recovery scenarios. By having multiple tiers of storage with different levels of redundancy, data can be protected against various types of disasters, including drive failures, natural disasters, or even human errors. The ability to quickly recover data from redundant copies or cache can significantly reduce the recovery time and minimize the impact of a disaster on data availability.
Performance Optimization: Storage tiering and caching strategies can optimize the performance of NAS devices like Asustor LOCKERSTOR 2 Gen2. By leveraging faster storage tiers or cache, frequently accessed data can be delivered more quickly, improving overall system performance. This can be particularly beneficial in scenarios where multiple users are accessing the NAS simultaneously or when dealing with resource-intensive applications.

However, it's important to note that the effectiveness of storage tiering and caching strategies depends on factors such as the workload, data access patterns, and the specific implementation. It's recommended to carefully plan and configure these strategies based on the specific requirements and characteristics of the data being stored on the NAS device.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS LOCKERSTOR 2 Gen2 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:
