Questions about this item

What PCIe generation does the 16 TB M.2 NVMe SSD use, and what throughput does that limit it to?

The 16 TB M.2 PCIe 4.0 x4 NVMe SSD is capped at PCIe 4.0 speeds, limiting sequential throughput to the 4.0 interface maximum.

What are the exact chassis dimensions and weight for checking bag or desk fit?

The chassis measures 15.91" wide, 12.09" deep, 1.26" high and weighs 7.94 lbs.

How is the DDR5 memory installed, and which slot population rule is often missed?

The 32 GB DDR5 5600MHz ships as two 16 GB modules in dual-channel slots; the common mistake is adding a third stick instead of replacing the pair with a matched kit.
