APPROXIMATELY 7 TIMES FASTER THAN SATA SSD
NVMe. Standing for “Non-Volatile Memory Express,” NVMe is an open standard developed to allow modern SSDs to operate at the read/write speeds their flash memory is capable of.
It allows flash memory to operate as an SSD directly through the PCIe interface rather than going through SATA and being limited by the slower SATA speeds.
Put another way, it’s a description of the bus the component uses to communicate with the PC, not a new type of flash memory.
It is also unrelated to the form factor, which is why NVMe drives can come in both M.2 or PCIe card form factors.
With both form factors, the component is connecting electrically to the PC via PCIe rather than SATA.
