SSD vs. NVMe – What’s the Difference?

SSD and NVMe are both storage devices but have a difference between them. The complete form of SSD is solid state Drive. On the other hand, the full name of NVMe is Non-volatile Memory Express.

Major Differences?

Moreover, NVMe is more fastest as compared to SSD. An SSD can be an NVMe, but an NVMe can not be an SSD. In short, there is no competition between both. Here we try to clarify the main difference between SSD and NVMe.

What is SSD?

SSD is a storage device that can store about 600MB of data in a second. The full name of SSD is solid state Drive. The primary function of SSD is to transfer data from one device to another. But it is pretty slow compared to NVMe. Moreover, it is efficient but demands low power in its work.

Furthermore, it refers to end-to-end encryption and saves data from hacking; no one can see your data. SSD demands comparatively low cost than others. In addition, SSD has compatibility to connect with every device. Lastly, it was invented in 1991. It is quite a safe and robust device and cannot be managed easily.


  • It is comparatively low costly
  • Has more capability to store data
  • Offers end-to-end encryption
  • Good performance
  • Transfer the data slowly
  • Speed is 600 MB per second
  • Compatible with all devices
  • Cannot physically damage

What is NVMe?

NVMe is a highly used device that stores a large amount of data. The full name of NVMe is non-volatile memory Express. It was invented in 2011. Moreover, it can store up to 2000 MB of data in a second due to its highest speed. Furthermore, NVMe is the fastest device as compared to SSD. It can be inserted into almost all devices. In addition, the size of the NVMe device is 2.5 inches, which can be connected or fit with all storage systems of the PC. Lastly, it is a more power-efficient device as opposed to SSD.


  • High capability to store data
  • End-to-end encryption
  • Transfer data very fastly
  • Compatible with all devices
  • Cannot default
  • Speed is 2000 MB per second

Key Differences between NVMe and SSD

  1. NVMe is much fastest in contrast to SSD.
  2. NVMe is an abbreviation for non-volatile money express. On the other hand, the full name of SSD is Solid State Device.
  3. NVMe can store up to 2000 MB of data in a second, whereas SSD can store 600 MB in a second.
  4. NVMe demands more power efficiency as opposed to SSD.
  5. NVMe is an open logical device, while SSD is a storage device.
  6. NVMe can be SSD, but SSD can not be NVMe.

Comparison Chart of NVMe vs. SSD

Features NVMe SSD
Speed 2000 MB in a second 600 MB per second
Transferring data Fastly transfer Slowly transfer
Efficiency Demands more power efficiency Demands less power efficiency
Price Expensive Cheapest


In a nutshell, we can say that both NVMe and SSD are different. They have other functions and are an integral part of every Laptop or PC device.
