Jaka jest różnica pomiędzy DAS i NAS?

Introduction

In this tutorial, we will explore the differences between DAS (Direct Attached Storage) and NAS (Network Attached Storage) devices, and when it might be more beneficial to use one over the other. We will also demonstrate how to create a RAID 1 configuration in Windows 11 using a DAS device that lacks hardware RAID support. This guide is designed for anyone interested in expanding their data storage solutions effectively.

Step 1: Understand DAS and NAS

• DAS:

  • Directly connects storage devices to a computer (e.g., via USB or Thunderbolt).
  • Typically offers faster access speeds due to direct connections.
  • Limited to one computer unless shared over a network.

• NAS:

  • A dedicated file storage device that connects to a network.
  • Accessible by multiple users and devices simultaneously.
  • Designed for file sharing and remote access.

Key Differences

• Connection: DAS is directly attached to a computer, while NAS connects via a network.
• Use Case: DAS is suitable for personal use and local access, whereas NAS is ideal for collaborative environments and remote access.

Step 2: Choosing the Right Storage Solution

• Assess your storage needs:
  • Consider how many users will access the storage.
  • Determine if high-speed access is a priority.
• Evaluate the available budget for storage devices.
• Look into specific models, such as the Terramaster D4-320, which provides a good balance between cost and functionality.

Step 3: Selecting Drives for Your DAS or NAS

• Choose drives based on:
  • Capacity: Select sufficient storage size for your needs.
  • Type: Consider SSDs for speed or HDDs for larger storage.
  • Compatibility: Ensure the drives are compatible with your chosen device.

Step 4: Setting Up a RAID 1 Configuration

• What is RAID 1:

  • A storage configuration that duplicates data across two drives for redundancy.

• Steps to Create RAID 1 in Windows 11:

  1. Open the new Control Panel in Windows 11.
  2. Navigate to the Disk Management section.
  3. Right-click on one of the drives you want to include in the RAID setup.
  4. Select "New Mirrored Volume".
  5. Follow the prompts to select the second drive to mirror.
  6. Complete the setup and format the volume as needed.

Tips

• Ensure both drives are of the same size and type for optimal performance.
• Regularly back up your data, even with RAID, to prevent data loss.

Step 5: Testing Your RAID Configuration

• After setting up RAID 1, verify its functionality:
  • Check the status in Disk Management.
  • Perform data transfers to ensure redundancy is working.

Step 6: Connecting DAS to Another PC

• If you connect the DAS to a different PC:
  • Ensure that the operating system supports the RAID setup.
  • The new PC should recognize the RAID array without issues.

Conclusion

In summary, choosing between DAS and NAS depends on your specific needs for speed, accessibility, and collaboration. Setting up a RAID 1 configuration in Windows 11 is straightforward and enhances data safety. Always consider your storage requirements, and remember to back up your data regularly for added security.
