Who it fits

Key specs explained for this NAS

Processor: Quad-Core 2.0GHz

This CPU has four processing cores running at 2.0GHz. You get better performance when running multiple apps or handling virtual machines simultaneously. The quad-core design prevents bottlenecks during file transfers. Compare this to dual-core models if you plan to stream media or run Docker containers. It ensures smooth operation for home and small business users who need reliable multitasking capabilities without lag.

RAM Capacity: 4GB DDR4

The system includes 4GB of DDR4 memory for active tasks. This amount supports the NAS operating system and several concurrent applications. It allows for efficient caching and faster response times. If you intend to run virtual machines or heavy database queries, consider models with higher RAM. For basic file storage and media streaming, this capacity is sufficient for most everyday home and office workflows.

Drive Bays: 4-Bay

This unit holds four internal hard drives. You can configure storage for redundancy using RAID or combine drives for larger capacity. It suits users needing substantial local storage without buying multiple devices. Compare this to 2-bay models if you require higher data protection. The four-bay layout offers flexibility for expanding your storage pool as your data grows over time.

Network Connectivity: 2x 2.5GbE

The NAS features two 2.5 Gigabit Ethernet ports. This speed exceeds standard 1GbE connections, allowing faster file transfers across your local network. You can use link aggregation for increased throughput or redundancy for reliability. Check your router and switch compatibility to utilize these speeds. This setup benefits users moving large media files or backing up data quickly between devices.

Physical Design and Build Quality

According to the listing, the Asustor AS6604T measures 9.06 inches in length, 6.69 inches in width, and 7.3 inches in height. These dimensions allow it to fit comfortably on a desk or slide into a standard rack space. The unit weighs 6.53 pounds, providing a stable base that resists vibration during operation. This mass helps dampen noise from the internal fans and drive motors.

The chassis is described as a 4-bay enclosure, designed to hold four internal hard drives. This layout prioritizes storage density over expandability, making it suitable for users who need a compact footprint. The finish is not specified in the provided data, so you should assume a standard plastic or metal construction typical for this class of device. There are no details regarding button layouts or LED indicators in the source text.

This physical design suggests a focus on utility rather than aesthetics. The compact size makes it easy to place in a home office or a small server closet. The weight ensures it stays in place during heavy read/write operations. You get a straightforward, no-frills enclosure that protects the internal components while allowing easy access to the drive bays for maintenance or upgrades.

Setup and everyday use

Setting up the Asustor AS6604T begins with inserting your drives into the four available bays. The unit ships diskless, so you must provide your own storage. Once the hardware is assembled, you connect the two 2.5GbE ports to your network. This dual-port setup allows for link aggregation or failover, ensuring stable connectivity for daily operations. You also have three USB 3.2 ports available for peripheral connections. The system relies on its 4GB DDR4 RAM and Quad-Core 2.0GHz processor to manage these connections efficiently. This configuration supports running multiple services simultaneously without significant slowdowns. For everyday use, the NAS functions as a central hub for your data. You can utilize Asustor Backup Plan to schedule automatic backups from your PC or Mac. This feature ensures your files are protected without manual intervention. If you need remote access, Asustor EZ-Connect lets you reach your NAS from any mobile phone or computer. This is useful for checking files while away from home. For users who work with large files, Asustor EZ-Sync provides real-time file synchronization with versioning. This keeps your local and cloud spaces aligned. You also have access to over 200 free apps. These cover media streaming, photo syncing, and server backup tasks. If you use security cameras, the unit includes four free IP camera licenses. This allows you to set up a surveillance center without monthly fees. The hardware handles these tasks smoothly, making it a practical choice for home offices or small businesses.

Before you buy this NAS

You must purchase hard drives separately, as the AS6604T ships diskless. Ensure your chosen drives fit the 4-bay form factor and meet your capacity needs. The unit includes two 2.5GbE ports, so verify your router or switch supports these speeds to avoid bottlenecks. If you plan to use the two M.2 NVMe slots for caching, buy compatible SSDs in advance. The 4GB DDR4 RAM is sufficient for basic tasks, but consider if you need more for heavy virtualization. This model sits alongside other 1 options in our guide. It suits users who want a balance of power and simplicity. Check your network infrastructure and storage requirements before finalizing your purchase. The included IP camera licenses are a bonus for security setups. Keep firmware updates in mind for long-term stability.

Check before you buy

• Buy compatible hard drives since the unit ships diskless.
• Ensure your network supports 2.5GbE speeds for full performance.
• Purchase M.2 NVMe SSDs if you plan to use cache slots.
• Verify that 4GB RAM meets your multitasking and virtualization needs.
