What Exactly Is NAS
NAS, short for Network Attached Storage, literally means a device that is connected to the network and has a data storage function, so it is also called Network Storage. NAS is a dedicated data storage server, including storage devices (such as disk arrays, CD/DVD drives, tape drives, or removable storage media) and embedded system software, which can provide cross-platform file sharing functions.
In this tutorial, we are going to show you how you can access your RAID-based NAS drives and get data off before formatting, resetting, or re-configuring the NAS configuration.
Common NAS Data Loss Scenarios
A RAID-based NAS data loss could be due to the following reasons:
- Accidental deletion or formatting
- Abrupt power failure or improper shutdowns
- Server overheating
- Virus or malware attack
- OS crashes or other errors
- Hardware controller failure
- Multiple disk failure

How to Recover Data from NAS Hard Drive Step by Step
In simple terms, the procedure is to remove the disk from the NAS, connect the hard drive to your PC, and then use data recovery software to extract and save files.
Before recovering data, you need to:
1. Remove the disk from NAS. Power off and plug out disks one by one.
When you take disks out of the NAS, label them based on which bay they belong to. These marks will help you put them back together in the same way. Besides, when you remove the NAS drives, do not violate the warranty.
2. Connect the drive to your PC. You can use SATA cables to connect the disk directly to your PC's motherboard or use USB-to-SATA adapters together with power. When the disks show up on the PC and you are asked to "Initialize disks" or "Format" the connected NAS devices, don't do that.
3. Ensure enough external/internal hard drive or another network storage space (equivalent or more than the volume of recovered data from failed NAS drives) to keep the restored data from NAS.
4. Download NAS recovery software: EaseUS Data Recovery Wizard.
After finishing these preparations, launch EaseUS file recovery software to recover data on Synology NAS or other NAS services using a PC.
Step 1. Scan the RAID drive
Choose the RAID drive from which you wish to recover data, and then click "Scan". Wait for the scanning process to finish, the deleted files will show up one by one.
Step 2. Find and preview lost RAID files
You can use "Filter" as quick navigation to find deleted or lost files. Besides, you can also use Search to find your lost RAID drive files via its file name or file extension.
Step 3. Restore lost RAID drive files
Select the wanted files and click "Recover". Browse to save these files to another secure location.

NAS and RAID
NAS consists of multiple components, including hardware (one or more hard disks, processors, and RAM enclosed in a hard disk box) and software (an operating system that manages access and network connectivity. NAS devices with multiple hard disks usually have a RAID (Redundant Array of Independent Disks) for data redundancy. If RAID is enabled on the storage system, you can connect two or more hard disks to the system so that they operate as one very large, high-speed hard disk.
Most NAS devices use different types of RAID to ensure fault tolerance and data consistency. Many NAS vendors provide their customers with proprietary RAID management systems that are capable of combining different hard disks into fairly complex RAID systems, but users do not need to have much knowledge of RAID technology.
How Much Does a NAS Cost?
NAS devices are not cheap. A NAS that handles a lot of multimedia files will set you back at least a few hundred dollars, and that doesn't include the cost of hard drives, which can cost anywhere from $50 to $200.
However, NAS is more cost-effective than cloud storage. Assuming 1 TB of cloud storage costs $25 a month, 20 TB of cloud storage will set you back $500 a month. While you might pay a few thousand dollars for NAS storage and a few disk drives, it's a far better deal than the long-term investment in cloud storage.
NAS VS SAN
SAN, Storage Area Networking, is the development of the traditional DAS (Data Acquisition Station) technology, is suitable for a large number of data block access. The core of SAN technology is the SAN switch, which serves as a data exchange channel. It has the advantages of high speed, low latency, high data consistency, wide connectivity, remote support, and flexible management.
NAS is a dedicated network file server, which separates storage devices from servers and centrally manages data to release bandwidth, improve performance, and reduce costs. It is much cheaper and more efficient than using server storage.
NAS is different from SAN suitable for applications. SAN is suitable for large data block access, while NAS provides flexible personal and enterprise disk space services for office automation, advertising, education, tax, and more. NAS is mainly applied to free E-mail space registration, FTP server, multimedia and image industry, the financial securities industry, and other industries that require a large amount of data storage.
Network Attached Storage (NAS) devices are a great solution when your data volume exceeds the capacity of your desktop hard disk storage and you want to share access to files and media across multiple computers, phones, and tablets. If you experience data loss while using the NAS, use professional NAS data recovery software to help you quickly recover important data.
