Who it fits

Key specs explained for this NAS

Processor: Intel Celeron N5105

This quad-core chip runs at 2.0 GHz and uses a 10 nm process. It offers about 31% more performance than older Gemini Lake models. You get steady handling for file transfers, media streaming, and running virtual machines. This processor suits users who need reliable daily performance without the heat and power draw of high-end desktop CPUs.

RAM Capacity: 8GB DDR4-2933

The system includes 8GB of DDR4 memory running at 2933 MHz. This speed provides 40% more performance than slower DDR4 variants. Adequate RAM helps your NAS manage multiple concurrent tasks, such as serving files while running container apps. You benefit from smoother operation when handling heavy workloads or multiple users accessing data simultaneously.

Network Connectivity: Dual 2.5GbE

You receive two 2.5 Gigabit Ethernet ports for connecting to your network. This speed is 2.5 times faster than standard Gigabit Ethernet, allowing quicker large file transfers. You can bond these ports for increased bandwidth or redundancy. This setup is ideal for users with fast home networks who want to move data between the NAS and computers efficiently.

M.2 NVMe Slots: 4X

The unit features four slots for M.2 NVMe solid-state drives. These slots support PCIe 3.0 SSDs, which offer twice the performance of PCIe 2.0 devices. You can use these drives for caching to speed up frequent access or for high-performance storage. This flexibility allows you to upgrade storage speed independently of the main drive bays.

Included Storage: 3 x 1TB SSD

The bundle comes with three pre-installed 1TB WD Blue SSDs. This provides immediate storage capacity without buying drives separately. You get faster boot times and quicker application loading compared to traditional hard drives. This option is convenient for users who want a ready-to-use system with reliable solid-state performance right out of the box.

Design and build overview

According to the listing, the Asustor AS6706T measures 12 inches wide, 13 inches high, and 13 inches long. The chassis weighs 14.9 pounds. This substantial mass suggests a stable unit designed to remain stationary. The size allows it to fit in standard server racks or on sturdy shelves. You need adequate clearance around the unit for airflow, as the dense components generate heat during operation.

The build includes a flexible PCIe slot. This feature lets you install 10GbE network interface cards or additional M.2 SSDs. This design choice supports future upgrades without replacing the entire system. You can expand connectivity or storage speed independently. The layout prioritizes expandability, allowing you to tailor the NAS to your specific bandwidth or caching needs.

The exterior finish appears utilitarian, focusing on function over aesthetics. The weight and dimensions indicate a desktop or rack-mounted application rather than a portable device. You should place it in a well-ventilated area. The sturdy construction helps minimize vibration from the six drive bays. This stability is important for maintaining drive longevity and consistent performance during heavy read and write tasks.

Setup and daily use guide

The Asustor AS6706T arrives with three 1TB SSDs already installed. This initial configuration simplifies your first steps. You begin by connecting the dual 2.5GbE ports to your network. These interfaces provide a solid baseline for data movement. The system supports Wake on LAN and Wake on WAN. These features allow remote power management without physical access to the unit. You can also install additional hardware via the flexible PCIe slot. This slot accepts 10GbE network cards or M.2 SSDs. Adding a 10GbE NIC expands your bandwidth options for faster local transfers. The four M.2 NVMe slots offer further storage flexibility. You can populate these with PCIe 3.0 drives for enhanced speed. The included DDR4-2933 RAM ensures the system handles multiple tasks efficiently. For everyday use, the quad-core processor manages file operations smoothly. It supports media streaming and concurrent user access without bottlenecking. The USB 3.2 Gen2 ports provide high-speed external connectivity. You can connect peripherals or backup drives at 10Gbps. The unit’s substantial weight and size keep it stable during operation. You place it in a dedicated space, away from vibration sources. The pre-installed storage allows immediate data usage upon setup. You configure permissions and share folders through the admin interface. The hardware handles background tasks while you access files. The combination of fast Ethernet and ample RAM supports consistent performance. You benefit from the included SSDs for quick read and write speeds. The system scales as your needs grow. You add drives to the remaining bays or expand via PCIe. The design prioritizes reliability and straightforward integration into your existing network.

Before You Buy This NAS

This Asustor bundle includes three 1TB SSDs, but you will need additional drives for full capacity. The unit features six drive bays, so you can expand storage later. You should check if your current network equipment supports 2.5GbE speeds. If you need faster transfer rates, consider adding a 10GbE NIC to the flexible PCIe slot. The system uses DDR4-2933 RAM, which you may want to upgrade if you run many virtual machines. Keep the firmware updated to maintain security. This model fits well if you need high-speed SSD caching alongside bulk HDD storage. It suits users who want a pre-configured start but plan to grow their library. Compare this against other 1 options to see if bare-metal units offer better value for your specific needs.

Check before you buy

• Verify your router supports 2.5GbE for full speed
• Check PCIe slot compatibility for 10GbE upgrades
• Ensure you have space for additional drive bays
• Confirm RAM upgrade options if running VMs
