RAID is the abbreviation of Redundant Array of Independent Disks. Simply put, RAID is a technology that combines multiple independent physical hard disks in different ways to form a hard disk group (logical hard disk), thereby providing higher storage performance and data backup function than a single disk. The different ways to make up disk arrays are called RAID levels.
Although RAID disks have higher redundancy and fault tolerance, disk failures also occur from time to time. For example, RAID arrays cannot be accessed, RAID configurations damaged or rebuilt. In these cases, RAID data will be lost. Common causes of RAID data loss are as follows:
- Unintentional data deletion
- File system corruption
- Controller failure
- Incorrect RAID rebuilds
- Corrupted or broken RAID structure
- Virus or malware attack
- Abrupt power outage or surge
When you run into a RAID failure, stop using the RAID drives anymore. You should immediately shut down the system, do not attempt to reset the RAID, or repair the file system by checking the disk.
Then, you need to look for professional RAID recovery services. EaseUS provides you with effective RAID data recovery options. You can select the manual RAID recovery services or fix corrupted RAID disks and restore data at an affordable price. Or you can use its NAS RAID recovery software to retrieve EXT4 and Btrfs based NAS drives of Synology, QNAP, ASUSTOR, Buffalo, Western Digital, etc.

Network Attached Storage provides users with versatile data storage, management, and sharing solutions on different platforms. NAS uses multiple RAID configuration types like RAID 0, RAID 1, RAID 5, or RAID 10.
When there is an issue in the NAS RAID device, such as accidental deletion, file system corruption, RAID formatting, or virus infection, you can try EaseUS NAS data recovery software to rescue and restore files efficiently.
EaseUS NAS data recovery software highlights:
- Recover data from NAS devices of Synology, QNAP, ASUSTOR, Buffalo, Western Digital, etc.
- Restore files from Btrfs and EXT4 file system drives
- Retrieve NAS data on Windows 11/10 and Windows Server 2022/2019/2016
Step 1. Select a NAS server and start recovering.
Download and install EaseUS Data Recovery Wizard on your Windows 11/10 64-bit computer. When you open this software, select "NAS Recovery". All the NAS servers will be automatically listed, choose your target NAS device and click "Scan".
Step 2. Enable SSH service on the NAS server.
Go to "Control Panel > Terminal & SNMP" to check the "Enable SSH service" box. Then view and remember the port for remote access open EaseUS Data Recovery Wizard and click "Next".
Step 3. Connect to the NAS server remotely.
This software will detect your IP and Port automatically. All you need to do is input the user name and password. If the IP address or Port is not right, you can correct it manually. Then, click "Connect Now".
Step 4. Recover lost/deleted NAS data
Then, EaseUS data recovery software will connect to your NAS and start a NAS device scanning. After the scan, you will see all the deleted, lost, or existing files on your NAS server.
You can apply the "Filter" feature or click the "Search files or folders" option to find the lost files on the hard drive. Select wanted NAS files that you lost on the server and click "Recover" to save them to another location.
Click the "Recover" button to restore deleted BitLocker files in Windows 10.

After continuous development, RAID technology has changed from RAID 0 to more RAID levels. In addition, there are some combinations of basic RAID levels, such as RAID 10 (a combination of RAID 0 and RAID 1), RAID 50 (a combination of RAID 0 and RAID 5), and so on. Different RAID levels represent different storage performance, data security, and storage costs. But we most commonly use the following RAID forms.
|RAID 0||RAID 0, also known as Stripe or Striping, provides the highest storage performance of all RAID levels. It combines two hard disks into one disk and continuously divides data on each disk. However, RAID 0 does not provide data protection. If any hard drive is damaged, all data will be lost. Therefore, RAID 0 cannot be used in critical areas that require high data availability.|
|RAID 1||RAID 1 implements data redundancy through disk mirroring and generates mutually backup data on pairs of independent disks. It provides high data security and availability. When a disk fails, the system automatically switches to the mirror disk without regrouping the failed data. RAID 1 has the highest unit cost of any disk array because its capacity is only equal to that of a hard disk.|
|RAID 5||RAID 5 is a storage solution that balances storage performance, data security, and storage cost. RAID 5 provides the same data read speed as RAID 0, higher disk space utilization, and lower storage cost than RAID 1. Therefore, RAID 5 is widely used.|
|RAID 6||Based on RAID 5, RAID 6 technology is designed to enhance data protection further. RAID 6 provides high data redundancy. However, the write efficiency is worse than RAID 5 due to the addition of parity, and the control system design is more complex. The parity area of the second block also reduces the effective storage space.|
|RAID 10||Raid 10 is a combination of Raid 1 and Raid 0. It uses parity check to implement stripe mirroring. RAID 10 is cost-effective because RAID 0 provides high read/write efficiency, and RAID 1 provides high data protection and recovery capabilities. Almost all RAID controller cards support this level. However, the storage capacity utilization of RAID 10 is 50% as low as that of RAID 1.|
The Bottom Line
Repairing RAID disks and restoring data is not easy for common users. However, if you are caught in a dilemma, do not hesitate to contact us, and we will provide you with timely RAID recovery services. You can choose either remote recovery services or NAS data recovery software to restore deleted or lost files from RAID drives based on your situation.
