The NAS asustor NIMBUSTOR 2 GEN2 AS5402T is a 2-bay network-attached storage appliance powered by an Intel Celeron N5105 quad-core processor and equipped with 8 GB DDR4 memory. It offers two 2.5 GbE network ports for increased throughput, three USB 3.2 ports for external peripherals, an HDMI 2.0b output for direct multimedia playback, and four M.2 NVMe slots for cache acceleration or dedicated SSD storage. The system is designed to deliver a balance of performance, connectivity and storage expansion for home and small office environments.
Advantages
The AS5402T combines a quad-core Intel Celeron N5105 CPU with 8 GB of DDR4 RAM to support multitasking, file serving and media transcoding. Dual 2.5 GbE ports enable higher network bandwidth than standard Gigabit Ethernet, reducing transfer times for large files and improving multi-user access. Four M.2 NVMe slots allow configuring high-speed cache or adding SSD volumes without occupying the 2.5" drive bays, while HDMI 2.0b provides direct 4K output to displays or TVs. Multiple USB 3.2 ports make it easy to attach external drives, printers or UPS devices for an expanded feature set.
Suitable for
- Centralized file storage and sharing for home or small office users
- Scheduled and incremental backups of PCs and mobile devices
- Media streaming and direct 4K playback via HDMI to a TV or monitor
- Cache acceleration for improved I/O performance in multi-user environments

How to use
Install 3.5" or 2.5" SATA drives into the two front bays or populate the M.2 NVMe slots for cache or additional SSD storage. Connect the NAS to your network via one or both 2.5 GbE ports; link aggregation can be configured if supported by your switch to increase throughput or provide redundancy. Power on the unit and complete the initial setup using the asustor setup utility or web interface to create storage pools, set up shared folders, user accounts and backup tasks. Use the HDMI output to connect a display for direct media playback, or stream content over the network to compatible devices. Attach external USB drives, printers or UPS devices to the USB ports as needed.
Usage recommendations
For consistent multi-user performance, enable SSD caching using the M.2 NVMe slots and consider link aggregation across the two 2.5 GbE ports when your network infrastructure supports it. Regularly configure and verify backup tasks and use the built-in power management options to protect drives and reduce wear.
