What is the difference between a PCI-E SSD and an NVME SSD? Which one is how much faster?

PCIe SSDs and NVMe SSDs are both types of solid state drives (SSDs) that use a Peripheral Component Interconnect Express (PCIe) interface to connect to a computer. The main difference between the two is the protocol they use to communicate with the computer.

NVMe (Non-Volatile Memory Express) is a newer protocol that was specifically designed for SSDs and takes advantage of the high-speed PCIe interface to deliver faster performance than older protocols like AHCI (Advanced Host Controller Interface). NVMe SSDs are generally faster than PCIe SSDs, especially when it comes to accessing small files or performing many small reads and writes.

In terms of actual performance, the difference between a PCIe SSD and an NVMe SSD can vary depending on the specific models and their hardware specifications. However, as a general rule, NVMe SSDs tend to be faster than PCIe SSDs. In some cases, the difference in performance can be significant, with NVMe SSDs offering read and write speeds that are several times faster than those of PCIe SSDs.
