PRODUCT REVIEW
In-Depth U.S. Market Review
The BUFFALO LinkStation 720 4TB NAS for Home Use is a mid-range, pre-populated network-attached storage (NAS) system geared toward the general U.S. consumer who needs an easy, reliable, and centralized file server with built-in data protection. Its niche is providing a seamless, out-of-the-box private cloud experience without the technical complexity of building a diskless system. The 4TB size is an ideal entry point for a family's initial backup and media consolidation efforts.
It is highly competitive due to its ready-to-go, RAID-enabled configuration and its inclusion of a modern 2.5 Gigabit Ethernet (2.5GbE) port. Compared to external USB hard drives, the Buffalo LinkStation 720 offers shared network access for multiple users and, most importantly, automatic RAID 1 mirroring for redundancy. You should choose this NAS if you prioritize ease of use, network accessibility, and hardware-level data safety for your family's most important files.

1. Pre-Configured Redundancy and Reliability
The major appeal of the BUFFALO LinkStation 720 4TB is its out-of-the-box data safety . It comes with two 2TB hard drives pre-installed, and it is usually configured in a RAID 1 (mirroring) setup. This means that if one of the two internal drives fails, your data is safe on the other.
For the non-technical U.S. user, this is a massive advantage. You don't have to worry about buying drives, installing them, or configuring complex settings; you simply plug it into your router, and your files are immediately protected at the hardware level.
2. Network Speed Advantage with 2.5GbE
While 4TB is an entry-level capacity, the 2.5 Gigabit Ethernet (2.5GbE) port is a premium feature that drastically improves the user experience. You can expect significantly faster file transfers than a standard NAS, which is a major benefit when performing a large, multi-hour initial backup of a family computer.
This speed boost makes the NAS feel highly responsive, even when several people are accessing files or streaming media simultaneously. It ensures that the LinkStation 720 integrates seamlessly with the faster Wi-Fi 6 and Wi-Fi 7 routers common in modern homes.
3. Private Cloud and Multi-User Access
As a Network Attached Storage device, the LinkStation 720 is designed for multi-user, multi-device access. You can set up personalized user accounts for everyone in the family, ensuring each person has their own secure storage partition.
The built-in software also facilitates remote access , creating a private cloud. This means you can securely retrieve files or upload photos from your phone or a remote computer while traveling, without paying a monthly subscription fee to a public cloud provider.
