Image of Kingston Technology SSD Interface Comparison: SATA vs. NVMe - NVMe SSDs

Non-Volatile Memory Express (NVMe) technology was introduced in 2011 to address the various bottlenecks of the SATA interface and communication protocols. NVMe technology utilizes the PCIe bus, instead of the SATA bus, to unlock enormous bandwidth potential for storage devices. PCIe 4.0 offers up to 32 lanes and in theory, can transfer data up to 64,000 MB/s compared to the 600 MB/s specification limit of SATA III. The NVMe specification also allows for 65,535 command queues, which can have up to 65,536 commands per queue, whereas the SATA-based SSDs are limited to a single queue with a depth of only 32 commands per queue. NVMe technology creates massive potential for storage devices via increased efficiency, performance, and interoperability on a broad range of systems. It is commonly believed that the technology will become the new industry standard.
