An NVMe SSD (Non-Volatile Memory Express Solid State Drive) is a type of storage device that uses flash memory to store data. It connects directly to the motherboard via the PCIe (Peripheral Component Interconnect Express) interface, allowing for much faster data transfer speeds compared to traditional hard drives and older SSDs that use the SATA interface. NVMe SSDs are designed to take advantage of the high-speed capabilities of modern processors and memory. This results in quicker boot times, faster file transfers, and improved overall system performance, making them ideal for gaming, video editing, and other data-intensive applications.
