FAQs:
1. Are hard drives included with this NAS?
No, this is a diskless model. You need to purchase and install your own 3.5-inch or 2.5-inch SATA hard drives or SSDs separately. We recommend NAS-specific drives for 24/7 reliability.
2. What are the advantages of a 4-bay NAS over a 2-bay model?
A 4-bay NAS offers greater storage capacity and supports more advanced RAID levels like RAID 5, which provides data redundancy (protection against a single drive failure) without losing 50% of your capacity like RAID 1.
3. Can I access my files remotely from my phone?
Yes, the UGREEN OS provides secure remote access functionality. You can access, download, and upload files from anywhere using the dedicated mobile app or a web browser.
4. Is this NAS good for a small business?
Absolutely. Its 4-bay capacity, support for RAID 5, and 2.5GbE speed make it an excellent central file server for a small team, providing shared storage, automated backups, and secure remote access.
5. How does the AI Photo Album work?
The AI engine automatically scans your photos and identifies faces, objects, and locations. It then creates searchable albums, so you can instantly find all photos of a specific person or from a certain vacation.
6. Can I connect it directly to my TV?
Yes, the 4K HDMI port allows you to connect the NAS directly to a television or monitor, turning it into a powerful standalone media player for your movie library.
7. Where can I find warranty information?
UGREEN NAS products are covered by a warranty. Please visit our warranty and support page for detailed terms and conditions.
8. Is the system really beginner-friendly?
Yes, UGOS Pro is designed with a clean, intuitive interface that guides you through setup, app installation, and creating shared folders, making it accessible for users new to NAS devices.
9. What is the power consumption like?
Thanks to its energy-efficient ARM architecture, the DH4300 Plus consumes significantly less power than NAS devices with x86 CPUs, making it cheaper to run 24/7.
