ASUSTOR AS5402T 2-bay NAS, Celeron N5105, 4 GB DDR4, 4 M.2 slots

Two-bay NAS with quad-core Celeron N5105

The ASUSTOR AS5402T is a diskless desktop NAS built around a quad-core Intel Celeron N5105 processor running at 2.0 GHz. It ships with 4 GB of DDR4-2933 memory and provides four M.2 slots for NVMe SSDs. Dual 2.5-Gigabit Ethernet ports, three USB 3.2 Gen 2 ports at 10 Gbps and an HDMI 2.0b output complete the connectivity. The unit is designed for 4K media transcoding and cross-platform live-stream backup.

Suits creators needing flash acceleration

This NAS fits users who want to combine traditional hard drives with up to four NVMe drives for cache or fast volumes, and who can use 2.5-Gigabit networking. It also serves households that need HDMI 2.0b output for direct 4K playback. Buyers who require more than two drive bays, ECC memory, 10-Gigabit Ethernet or a higher core count should look elsewhere.

Four M.2 slots decide flash capacity

The defining specification is the presence of four M.2 slots that accept NVMe SSDs. This allows the AS5402T to accelerate storage pools or act as a high-speed scratch volume for content creation. If a build does not need NVMe expansion, a simpler two-bay model without M.2 support will cover the same basic file-sharing role.
