What is a GaN charger?

GaN (gallium nitride) chargers use a more efficient semiconductor than traditional silicon, so they run cooler and can be much smaller at the same wattage — which is why multi-port USB-C chargers that power a laptop and phone together are usually GaN.

What is an NVMe SSD enclosure?

An NVMe enclosure turns an M.2 NVMe SSD into an external USB drive. Speed depends on the bridge chip and the port: USB 3.2 Gen 2 tops out around 10 Gbps, while USB4 and Thunderbolt enclosures can go several times faster.
