The fastest jot down of SSD you could get is a PCIe NVMe SSD.
These take advantage of the highspeed PCIe bus to support higher bandwidths.
NVMe stands for Non-Volatile Memory Express and is a protocol used to access storage devices over PCIe.
A communications bus is a communications system that transfers data between computer components.
What are PCIe lanes?
A PCIe lane is a set of four wires or signal traces on a motherboard.
Each CPU can only support a limited number of PCIe lanes.
Historically, consumer-grade Intel CPUs support 16 PCIe lanes while AMD supports 20.
High-end enthusiast CPUs and server CPUs often offer more PCIe lanes.
Tip: x16 is the standard way to show that a link uses 16 PCIe lanes.
Other connectors that use PCIe lanes are M.2, U.2 which use four lanes.
As such a DIMM.2 card can take either four or eight PCIe lanes.
These extra four lanes are used as a high-speed connector to the motherboard chipset.
The chipset splits the available bandwidth between a range of different functionality.
The lanes can only be run in x1, x4, x8, and x16 configurations.
