Asustor's all-flash-friendly 4-bay desktop NAS pairs an Intel N5105 quad-core with up to 16GB DDR4, dual 2.5GbE ports, and four internal M.2 NVMe slots that can be used either as a high-speed cache or as primary all-flash storage. Externally there are three USB Type-A 3.2 Gen 2 ports (10 Gbps — one front, two rear), an HDMI 2.0b output for direct 4K@60 video, and a Kensington security slot. The two 2.5GbE ports support link aggregation for combined throughput above 2.5 Gb/s, and the unit ships with an external 90W DC brick that uses a proprietary barrel jack rather than an IEC inlet.

Notes & Compatibility
The AS5404T is the Nimbustor 4 Gen 2; don’t confuse it with the Drivestor 4 Pro, which is the AS3304T. Three USB-A 3.2 Gen 2 (10Gbps) ports total — 1 front, 2 rear. Dual 2.5GbE ports support link aggregation. Four internal M.2 NVMe Gen3 slots are not exposed as external ports. Power comes from an external 90W adapter on a proprietary barrel jack (not listed in the port table). Each of the four M.2 slots is PCIe 3.0 x1, so an NVMe drive there tops out around 1 GB/s in theory — still more than the network can move. Link aggregation or SMB Multichannel across both 2.5GbE ports gives up to 5 Gbps combined. Memory: 4GB installed, 16GB maximum (2 × 8GB).
