NVMe
NVMe (Non-Volatile Memory Express) is a high-performance storage protocol specifically designed for SSDs, utilizing the PCIe (Peripheral Component Interconnect Express) interface for maximum speed. Traditional SATA SSDs have a theoretical maximum speed of around 600 MB/s, whereas NVMe SSDs can reach far higher speeds, depending on the PCIe generation and lanes used.
- PCIe 3.0 x4 NVMe SSDs: Typically offer read and write speeds up to 3,500 MB/s.
- PCIe 4.0 x4 NVMe SSDs: Can achieve speeds of up to 7,000 MB/s, nearly doubling the performance of PCIe 3.0.
- PCIe 5.0 x4 NVMe SSDs: Expected to reach speeds up to 14,000 MB/s, pushing storage access to unprecedented levels.
These speeds make NVMe ideal for data-intensive applications, such as video editing, gaming, and enterprise tasks like virtual machines and database management. NVMe’s high-speed capabilities are achieved by taking advantage of parallelism, allowing multiple commands to be processed simultaneously, thereby reducing latency and maximizing throughput.
