PCIe
it uses a PCIe BUS
The hard drive specification with the fastest theoretical bus speed is NVMe (Non-Volatile Memory Express) over PCIe (Peripheral Component Interconnect Express). NVMe drives can leverage multiple PCIe lanes, with current iterations supporting up to PCIe 4.0 and PCIe 5.0, allowing for speeds of up to 32 Gbps per lane or more. This results in significantly higher data transfer rates compared to traditional SATA drives, which are limited to around 6 Gbps. Overall, NVMe over PCIe provides the highest performance for storage solutions.
they may look similar but they are completely differ. the PCI-E has a higher bus speed than the PCI bus speed. since 2004 more devices are using PCI-E expansion.
A PCI Express x16 bus is significantly faster than the process of upgrading BIOS software. PCIe x16 can provide a theoretical bandwidth of up to 32 GB/s in its latest versions, while BIOS upgrades typically involve transferring small files and executing a relatively slow, controlled process that does not approach the speed of data transfer seen in PCIe. Therefore, in terms of raw speed and data throughput, the PCIe x16 bus is much faster.
PCIe version 2 doubled the fequency of the PCIe bus, theoretically doubling the throughput, It also allows for up to 32 lanes on one slot
As of right now, the fastest expansion bus found in a standard PC is a PCI-E or often seen as PCIe (PCI-E or PCIe stands for Peripheral Component Interconnect Express)Installing a PCIe card into your PC may be done only if the motherboards expansion slot will fit it. PCIe cards can fit into larger slots, but not smaller slots (obviously).
PCIe or USB 2.0 bus standards.

Unless it's a very old computer, your graphics card will be either PCIe (PCI Express) or AGP, and if it was bought within the last... Say, four and a half years, it will definitely be a PCIe setup for graphics with your other component cards running on a PCI bus. If it was a gaming computer sold post-2003ish it will also have a PCIe bus.
The most common PC expansion bus is the PCI Express (PCIe) bus. It has largely replaced older standards like PCI and AGP due to its higher speed and efficiency, offering multiple lanes for data transfer. PCIe is used for a variety of components, including graphics cards, SSDs, and network cards, making it essential for modern computing. Its scalability allows for different configurations, accommodating various performance needs.
