NAS devices offer faster performance, better security, and seamless remote access for all storage needs.
Synology DiskStation and Synology DS223j lead the market with reliability and advanced features.
Choosing the right Network Attached Storage ensures scalable, long-term data protection and organization.
Network-attached storage (NAS) devices are essential for both home and business use. These gadgets act as centralized storage systems that allow multiple users and devices to access and share files over a network. A NAS also provides features such as file backups, remote access, media streaming, and data protection.
As digital files, photos, and videos grow in size and volume, NAS devices are becoming increasingly important for keeping data safe, organized, and accessible. While cloud services are available for the same purpose, their subscription costs can be high; a NAS offers a reliable, long-term local storage solution. This article will discuss what to look for in a NAS device and review some of the top models available in 2025.
Below are some of the best Network Attached Storage devices from top brands that users can consider purchasing:
The Synology DiskStation DS923+ is one of the most popular 4-bay NAS devices, combining strong performance with great expandability. The 4-bay configuration supports various RAID setups, ensuring that data remains safe even if one drive fails. This device runs Synology’s advanced DiskStation Manager (DSM), known for its reliability and ease of use.
The DS923+ model is suitable for users who want to store large amounts of data, stream high-definition videos, or host multiple users at once. It also supports memory expansion and fast networking options, making it a great choice for homes, creative studios, and small offices.
Synology DS223j is a 2-bay NAS designed for beginners or those with lighter storage needs. Despite being an entry-level model, it offers many features of Synology’s more expensive products, such as automatic backups, cloud syncing, and remote file access. DS223j provides an affordable way to experience reliable network storage without sacrificing quality.
This device is ideal for people who want to store photos, videos, and documents in one place. It also supports basic media streaming and can serve as a personal cloud, allowing access to files from anywhere. Although it has fewer bays and lower performance than the DS923+, it is still one of the best-value NAS devices in the market.

QNAP TS-433-4G is a 4-bay NAS built for users who want solid hardware performance at a reasonable cost. QNAP offers strong processors and flexible configurations, making it suitable for both beginners and professionals. TS-433-4G handles tasks like file sharing, backups, and multimedia streaming with ease.
This NAS device runs QNAP’s QTS operating system, which provides a large range of applications for data management, security, and entertainment. It is best for small offices and home users who want a balance between affordability and capability. With options for 2.5 GbE networking, this model also offers faster data transfers than many standard NAS devices.
TerraMaster F4-212 is another strong contender in the 4-bay NAS category for 2025. It delivers solid performance at a budget-friendly price. Designed for home and small-office use, it supports various RAID configurations and provides features such as media streaming and file synchronization.
Although TerraMaster’s software is not as polished as Synology’s or QNAP’s, the F4-212 makes up for it with excellent hardware value. It is a great choice for users who need a reliable NAS for backups, file sharing, and data protection but do not want to spend a premium.
ASUSTOR Drivestor 2 Lite is a compact, affordable 2-bay NAS that focuses on simplicity and essential features. It is designed for storing files, performing regular backups, and streaming media within a household. ASUSTOR’s operating system offers useful apps for remote access, file synchronization, and data security.
Drivestor 2 Lite is quiet, energy-efficient, and easy to set up. It is perfect for home users who need central storage for photos, videos, and documents. Its affordability and reliable performance make it an excellent entry point into the world of NAS devices.
Selecting the best NAS depends on storage needs, number of users, performance expectations, and budget. A 2-bay NAS is sufficient for basic file storage, backups, and personal media streaming, while 4-bay models are better for multitasking, redundancy, and scalability.
Future expansion should also be considered. Devices like the Synology DS923+ or QNAP TS-433-4G allow additional drives and faster network upgrades, making them ideal for growing storage demands. For smaller or simpler needs, the DS223j or Drivestor 2 Lite remains an excellent cost-effective option.
Software and support are equally crucial. Synology offers the most user-friendly operating system, while QNAP focuses on performance and hardware features. TerraMaster and ASUSTOR provide more affordable alternatives without compromising reliability.

Buying a NAS with a bit more capability than currently required ensures long-term usefulness. Choosing a device with extra bays or upgradeable memory can help avoid future replacement costs. Network performance is another aspect that should not be overlooked. Investing in a NAS that supports faster Ethernet speeds will ensure smooth performance as home and office networks become faster.
Power stability is also important. Since NAS devices are often left running continuously, using an uninterruptible power supply (UPS) helps protect data in the event of a power outage. Regular backups to external drives or cloud services are also recommended, as RAID alone does not protect against accidental deletion or corruption.
Noise, heat, and location should be considered when setting up a NAS. Placing it in a well-ventilated area helps maintain performance and extend drive lifespan. Keeping the NAS connected to a reliable router or switch also improves stability and data transfer speed.
The latest NAS devices are more advanced, offering powerful hardware, improved software, and faster networking. Models like Synology DS923+ and QNAP TS-433-4G provide high-end performance and scalability, while DS223j and Drivestor 2 Lite are affordable options for simpler needs. TerraMaster F4-212 balances cost and functionality.
Selecting the right NAS device involves considering capacity, performance, and budget. A decent NAS not only keeps data safe but also helps organize digital data, making it accessible.
