Yes. It takes an NVMe M.2 SSD, in at least 2 slots.
The slot runs at PCIe 3.0 x4, up to about 3.9 GB/s. A faster PCIe 4.0 drive works too, at that speed. 3 machines run 2 NVMe drives at once. M.2 drives come in 2230, 2242 and 2280 lengths (30, 42 and 80 mm). Check the length printed on your current drive before you order.

Illustration Match the label on your charger.
We don't have this model's charger rating yet. The label on your charger shows it: the output line gives volts and amps, and volts times amps is the watts (19.5 V at 3.33 A is 65 W). Buy one with the same plug, the same voltage and at least as many watts.
