NVMe stands for “Non-volatile Memory Express” and is a storage module, that uses the highspeed interface “PCIe”, but unlike RAM isn’t volatile. Meaning that it keeps it’s data when powered off.
M.2 is the formfactor and is sometimes compared to “a stick of gum”.
Despite these names it is technically another form of “solid state drive”, since it has no moving parts and is usually consists of NAND flash memory.
All the technical stuff aside, these drives are directly connected to your motherboard(or on an expansion card) and using a highspeed interface, they can achieve read/write speeds between 3-6 times faster than traditional SATA SSD’s. And even faster on a motherboard supporting PCIe gen 4.
- Fastest type of storage
- Probably most expensive
- Requires an M.2 port on your motherboard or on an expansion card
