Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Synology often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Are there any known limitations or performance issues related to specific RAID levels in NAS Synology DiskStation DS509+ devices?

Yes, there are some known limitations and performance issues related to specific RAID levels in the Synology DiskStation DS509+ NAS devices.

RAID 5 and RAID 6: These RAID levels offer data redundancy by distributing parity across multiple drives. However, they have a higher write penalty compared to RAID 0 or RAID 1. As a result, write performance may be lower, especially for small random writes. Additionally, when a drive fails in RAID 5 or RAID 6, the system needs to recalculate the parity, which can put a strain on the performance during the rebuild process.
RAID 10: This RAID level combines mirroring and striping, offering both performance and redundancy. However, it requires a higher number of drives compared to other RAID levels. The performance of RAID 10 can be excellent for both read and write operations, but the usable capacity is limited to half of the total drive capacity due to mirroring.
SHR (Synology Hybrid RAID): This proprietary RAID implementation by Synology allows for mixed drive sizes and offers flexibility in expanding the storage pool. However, it may have slightly lower performance compared to traditional RAID levels due to the additional overhead of managing different drive sizes.
RAID Expansion and Migration: When expanding or migrating RAID volumes on a Synology DiskStation DS509+, the process can take a significant amount of time, especially for larger drives or volumes. During this process, the system may experience reduced performance.

It's important to note that the performance limitations and issues can vary depending on the specific hardware configuration, drive types, network environment, and workload characteristics. It is recommended to consult the official documentation or contact Synology support for detailed information specific to your DS509+ model.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS DiskStation DS509+ can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

Power off the NAS and disconnect it from the power source.

WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.
Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.
Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.
Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

How to Order Remote Data Recovery

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with Synology DiskStation DS509+. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

Overwriting during the recovery process;
Additional data loss caused by bad sectors;
User errors.

To create a disk image, follow these steps:

Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.
Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

Where Are the User’s Files Actually Stored?

The Synology DiskStation DS509+ network-attached storage keeps DSM (DiskStation Manager) 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.
