10 Best Synology Nas 2025 in the United States

The Synology DiskStation DS1621+ is a solid choice for anyone needing a reliable and spacious NAS for home or small office use. It comes with six drive bays, fully loaded here with six 10TB WD Red Plus drives, giving you a hefty 60TB of storage right out of the box. This makes it ideal for storing large amounts of data like backups, multimedia files, or work documents.

The AMD Ryzen quad-core 2.2 GHz processor and 4GB RAM ensure the system can handle multiple tasks smoothly, from file sharing to virtualization and backup solutions. It supports four Gigabit Ethernet ports, providing good network connectivity for fast data access and redundancy. On the software side, Synology’s DiskStation Manager is user-friendly and packed with features to manage files, automate backups, and even run virtual machines if needed.

The memory is somewhat modest at 4GB—upgrading RAM could improve performance for heavy multitasking or large-scale virtualization. Also, while the included WD Red Plus drives are reliable mechanical disks spinning at 7200 RPM, they won’t match the speed of SSD-based setups, which might matter if you need super-fast access. The unit is a bit heavy at over 21 pounds and fairly large, so keep that in mind if space or portability is a concern. For those seeking large storage capacity combined with good performance and a rich set of management tools, the DS1621+ offers a well-balanced solution without being overly complex.

The Synology DiskStation DS923+ is a versatile and powerful 4-bay NAS server supporting up to four hard drives, providing ample storage options depending on your needs. The device runs on an AMD Ryzen R1600 dual-core processor with speeds up to 3.1 GHz and comes with 8GB of DDR4 RAM, enabling smooth multitasking. It also includes a 256GB M.2 NVMe SSD, which enhances system responsiveness by speeding up caching and important tasks. For connectivity, it offers two USB ports and supports network connections that ensure fast data transfers.

The NAS runs on Synology’s user-friendly DiskStation Manager (DSM) software, featuring an easy interface and rich applications such as data protection, cloud sync, and multimedia support, making it accessible even for users without deep technical expertise. The DS923+ is sold as an enclosure only, requiring you to purchase your own hard drives, which adds to the initial setup cost. While its integrated graphics and processor handle most tasks well, it may not be ideal for demanding workloads like 4K video transcoding for multiple users. This NAS is a solid choice for reliable, expandable storage with strong processing power and excellent software support for everyday storage and backup needs.

The Synology DS1821+ is a solid choice if you need a reliable NAS with plenty of storage. It offers 8 drive bays, allowing you to install up to eight hard drives or SSDs, which is great for users needing large storage capacity or future upgrades. Included in this bundle are eight 6TB Seagate IronWolf drives, giving you a total of 48TB out of the box, suitable for extensive file storage, backups, or media libraries. The AMD Ryzen quad-core processor combined with 4 GB of error-correcting RAM ensures smooth performance for activities like file sharing, virtualization, and streaming media. Having four Gigabit Ethernet ports means it can handle fast network speeds and provide network redundancy or link aggregation, which is helpful in business or advanced home setups.

The device also supports adding SSD cache via two M.2 NVMe slots, which can speed up data access when working with frequently used files. Another strong point is its expandability; you can increase storage up to 18 bays by attaching expansion units, which is excellent for growing data needs. Synology’s software ecosystem is user-friendly and packed with features for backups, virtualization, and multimedia, making management easier even if you’re not a tech expert.

On the downside, the drives included spin at 5400 RPM, which is quieter and more energy-efficient but slightly slower compared to 7200 RPM drives, so transfer speeds might be moderate for very demanding workloads. Also, while 4 GB RAM is adequate, upgrading it might improve performance with heavier multitasking or running multiple apps. This NAS is ideal for small to medium businesses or tech-savvy home users who want a balance of storage capacity, performance, and expandability.
