FAQs
- 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.
