This is the all-time low for the TS-AI642, beating its previous floor by a comfortable margin. Over the last 30 days the unit has averaged $741.78, and the 90-day average sits at $744.02, so today's price cuts roughly $105 off what buyers have been paying.

For just $636.70, down from its list price of $749, you are getting a genuine bargain on a recent-generation AI NAS, not a clearance-bin leftover.

What You're Getting

The TS-AI642 runs on an ARM Cortex 8-core processor pairing four Cortex-A76 cores at 2.2 GHz with four Cortex-A55 cores at 1.8 GHz, backed by 8GB of DDR4 RAM. The bundled ARM Mali-G610 MC4 GPU accelerates video processing for smoother media playback and AI workloads. On the network side you get a single 2.5GbE port plus dual 1GbE ports, which keeps large file transfers from bottlenecking. Two PCIe Gen 3 x2 slots let you drop in a faster 10GbE adapter, a QM2 card, or a USB 3.2 Gen 2 card.

Two 4K HDMI 1.4b outputs handle surveillance feeds and high-resolution playback, so this box does double duty as a home theater hub.

Who This Is For

This is aimed at power users and small teams who need more than a two-bay box: media collectors with large 4K libraries, photographers managing big RAW archives, and homelab builders who want room to expand. Six bays give you real capacity for RAID setups with redundancy and performance.

If you just need basic file backup, a cheaper two-bay unit will do the job, but anyone past that stage will outgrow it fast.

The Caveat

The 8GB of RAM is soldered and non-expandable, so if you plan to run heavy containers or VMs alongside storage duties, factor that ceiling in before committing. Light to moderate app loads are fine; a full virtualization lab is not this box's lane.

Final Verdict

The Cortex-A76/A55 combo and dedicated GPU make this one of the more capable ARM NAS units in this price band, and at $636.70 you are paying less than the 30-day average for a machine that just hit its record low. If a six-bay AI NAS is on your list. This is the price to move on.
