How to Choose a NAS
When shopping for a NAS, there are three key factors worth paying close attention to.
1. Number of Drive Bays A 2-bay NAS can run RAID 1 (mirroring) to protect your data against a single drive failure. 4-bay models open up RAID 5 and 6, offering a better balance of capacity, performance, and redundancy. If you’re just getting started with NAS, 2 bays is a sensible starting point.
2. CPU and RAM Processor and memory determine how well the NAS handles simultaneous users and demanding tasks. Generating photo thumbnails, running AI-powered photo organization, or transcoding 4K video on the fly all require more processing power. For basic file sharing and backups, an entry-level CPU is sufficient.
3. Software Ecosystem Synology DSM, QNAP QTS, and TerraMaster TOS each offer different experiences. Synology’s DSM is widely considered the most intuitive and beginner-friendly, with an extensive app library and strong documentation. It’s the recommended choice unless you have a specific reason to look elsewhere.

Product Details
1. Synology DS224+ — Our Top Pick
The DS224+ is the most well-rounded 2-bay NAS for home and SOHO use. Its Intel Celeron J4125 handles 4K H.265 real-time transcoding, AI-powered photo organization in Synology Photos, and smooth multi-user access without breaking a sweat. DSM’s clean interface is easy for anyone to navigate, and the app library is the most extensive in the NAS market.
2. QNAP TS-233 — Best Value. Most Affordable Option
At around $160, the TS-233 is the most budget-friendly 2-bay NAS available. It handles file sharing and backup tasks reliably. QTS is more complex than DSM, but offers flexible configuration options once you’re comfortable with it. If keeping costs low is your top priority, this is the pick.
3. Buffalo LinkStation LS710D — Most Popular in Japan
Buffalo’s LinkStation series has a strong following in Japan thanks to reliable domestic support and straightforward setup. The single-bay design suits simple backup scenarios, and the Japanese-language support resources make it a good choice for users who prefer local assistance.
4. Synology DS923+ — Best 4-Bay NAS for Power Users
The DS923+’s AMD Ryzen R1600 dual-core CPU handles heavier workloads—think multiple simultaneous users, surveillance feeds, or running Docker containers alongside file sharing. Adding a 2.5GbE adapter unlocks faster local transfer speeds. The full Synology app ecosystem (Drive, Surveillance Station, Active Backup for Business) makes this a capable small-business platform.
5. TerraMaster F4-423 — Best 4-Bay for Spec-Per-Dollar
The F4-423 pairs an Intel N95 quad-core CPU with 4GB RAM and built-in 2.5GbE—specs that edge out similarly priced Synology hardware on paper. TerraMaster’s TOS software has improved significantly in recent years. If you’re willing to invest time in setup and want the most hardware for your money in a 4-bay form factor, this is worth considering.
Summary
When choosing a NAS, the Synology DS224+ is our top recommendation. Its combination of capable hardware, best-in-class software, and long-term support makes it the right choice for most users. On a tight budget, the QNAP TS-233 delivers solid value. For serious power users who need a 4-bay setup, the Synology DS923+ is the most well-rounded option.
