This asustor lockerstor 4 gen2 as6704t review focuses on the AS6704T v2 bundle with 12TB of SSD storage. It is a 4-bay network-attached storage device designed for speed and connectivity. Two specs define its core capability: the Intel Celeron N5105 quad-core processor and dual 5-Gigabit Ethernet ports. The included 3 x 4TB WDS400T4B0E SSDs provide fast read and write performance for demanding workloads. You get four M.2 slots for future expansion, along with 4 GB of DDR4 RAM. This setup targets users who need reliable, high-throughput storage for media or virtualization tasks.
What stands out
- Quad-Core 10 nm Intel Celeron N5105 CPU for efficient processing
- Dual 5-Gigabit Ethernet ports for increased network throughput
- 4x M.2 slots for NVMe SSD expansion
- Includes 3 x 4TB SSDs (WDS400T4B0E) for immediate use
- 4 GB of DDR4-2933 RAM for system stability
Who it fits
Good fit for
This NAS suits home labs, small offices, and creators who need fast local storage. The dual 5GbE ports allow for link aggregation or separate network traffic, which helps when handling large media files. The included SSDs ensure quick access to data, making it ideal for video editing or virtual machines. If you already have some drives and want a powerful base unit with ample RAM and CPU headroom, this bundle offers a solid starting point for a high-performance storage server.
Who should skip it
You should look at another option if you need more than four drive bays. This unit is limited to a 4-bay configuration, so it will not satisfy users requiring massive raw capacity for archival purposes. Additionally, the 4 GB of RAM may be insufficient for heavy virtualization tasks or running many containers simultaneously. If you require 10GbE networking or more than two USB ports, this model does not meet those specific connectivity needs.
Verdict: The Asustor AS6704T v2 bundle delivers a balanced mix of processing power and fast SSD storage for small teams. Its dual 5GbE ports and quad-core CPU make it a capable choice for performance-focused users.

The bundle includes three 4TB solid-state drives for a total of 12TB. SSDs offer faster read and write speeds than traditional hard drives. This setup reduces load times for applications and media. You have one empty bay for expansion or redundancy. Consider how the SSD speed matches your network capabilities for best results.
Physical Design And Build Specs
The Asustor Lockerstor 4 Gen2+ measures 12 inches wide, 13 inches tall, and 10 inches deep. It weighs 11.9 pounds. These dimensions indicate a substantial footprint. You need a sturdy shelf or desk space to accommodate its height and width. The weight suggests a stable chassis that resists vibration from the internal drives. This stability helps protect your data during high-speed operations.
According to the listing, the unit features dual 5-Gigabit Ethernet ports. This layout allows you to bond connections or separate network traffic. You can dedicate one port to storage traffic and the other to general internet access. The design also includes two USB 10Gbps ports. You can use these for fast external backups or connecting high-speed peripherals. The presence of an HDMI interface means you can connect the NAS directly to a display for local management or media output.
The device supports four M.2 NVMe slots and comes with 4GB of DDR4-2933 RAM. This internal layout prioritizes speed over raw capacity expansion. You benefit from rapid read and write speeds for caching or running applications. The build focuses on connectivity and performance density. You get a compact yet powerful unit that fits into professional or serious home setups. The physical design reflects a focus on modern, high-throughput storage needs.
Setup And Everyday Use
Setting up this NAS begins with connecting the hardware. You plug in the dual 5-Gigabit Ethernet ports for network access. The device includes three 4TB SSDs, so you do not need to buy drives separately. These are installed in the four M.2 NVMe slots. The fourth slot remains empty, giving you room for future expansion. You also connect the two USB 10Gbps ports if you need fast peripheral access. The system runs on an Intel Celeron N5105 quad-core processor. This chip manages file transfers and app tasks. You get 4 GB of DDR4 RAM to support these operations. This memory helps keep multiple apps running smoothly at once. In daily use, the dual 5GbE ports allow for high-speed data movement. You can transfer large files quickly between your computer and the NAS. The Wake on LAN and Wake on WAN features let you power the device remotely. You do not need to be near the unit to start it. The HDMI interface provides direct video output if you connect a monitor. This setup supports media streaming without extra hardware. The included SSDs ensure fast read and write speeds. You benefit from quick backup times and rapid file access. The system is designed for consistent performance in home offices or small teams. You rely on the quad-core CPU and dual network ports for stability. The four-bay design offers flexibility as your storage needs grow.
Check Your Setup Before Buying
You should verify your network infrastructure before relying on this unit. The dual 5-Gigabit Ethernet ports require compatible switches and routers to function at full speed. If your current setup only supports 1-Gigabit connections, you will not see the expected performance gains from the Intel Celeron N5105 processor. You also need to check physical space. At 13 inches tall and 11.9 pounds, it is heavy and tall. Ensure your shelf can support the weight and height. The included three 4TB SSDs fill three of the four bays. You have one empty M.2 NVMe slot for future expansion. This makes the device suitable for users who want immediate storage but plan to upgrade later. It fits well among 1 options for those prioritizing speed over raw capacity. You should also confirm that your applications support Wake on LAN if you need remote access features. Regular firmware updates from Asustor will keep the system secure and stable over time.
Check before you buy
- Verify your router supports 5-Gigabit Ethernet speeds.
- Ensure your shelf can hold 11.9 pounds.
- Confirm space for the 13-inch height.
- Check if you need the fourth M.2 slot.
- Review Asustor firmware update schedule.
