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 QNAP 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 quality of service (QoS) settings impact data transfer reliability on NAS QNAP VS-8032U-RP devices?

Quality of service (QoS) settings can have a significant impact on data transfer reliability on NAS QNAP VS-8032U-RP devices. Here are a few ways QoS settings can affect data transfer reliability:

Bandwidth allocation: QoS settings allow you to prioritize and allocate bandwidth to different applications or services. By properly configuring QoS, you can ensure that critical data transfers receive sufficient bandwidth, reducing the chances of congestion and packet loss. This can greatly improve the reliability of data transfers.
Traffic prioritization: QoS settings enable you to prioritize certain types of traffic over others. For example, you can prioritize real-time video streaming or VoIP traffic over file transfers. By giving higher priority to critical traffic, you can ensure that data transfers are not affected by lower-priority activities, thus improving reliability.
Traffic shaping: QoS settings also allow you to shape or control the flow of traffic. You can limit the bandwidth usage of specific applications or services to prevent them from overwhelming the network and causing data transfer issues. By shaping the traffic, you can maintain a more stable and reliable data transfer environment.
Buffer management: QoS settings can also help manage buffer sizes and buffer thresholds. Buffers are used to temporarily store data packets during transmission. By optimizing buffer management through QoS settings, you can reduce latency and minimize the chances of packet loss, thereby enhancing data transfer reliability.
Prioritizing specific devices: QoS settings can be used to prioritize traffic from specific devices or IP addresses. This can be useful in scenarios where certain devices or users require consistent and reliable data transfers. By giving them higher priority, you can ensure their data transfers are not adversely affected by other network activities.

Overall, properly configuring QoS settings on NAS QNAP VS-8032U-RP devices can help optimize network resources, minimize congestion, and prioritize critical data transfers. This, in turn, improves the reliability of data transfers and ensures a smoother user experience.

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

Although NAS VS-8032U-RP 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:

Turn off the storage and disconnect it from the power supply.

WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.
Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Where are user’s files stored?

The QNAP VS-8032U-RP network-attached storage keeps QTS (QuTS hero) operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.
