While SSDs are dramatically faster than traditional HDDs, an even faster option is using NVMe M.2 drives with speeds up to 3,500 MB/s.

You already know what a Solid State Drive (SSD) is and probably have one installed in your laptop or Chromebook. Compared to a traditional spinning hard drive, an SSD is much faster — which is why we recommend installing an SSD as the best way to improve the performance of an older desktop or laptop computer. That is until we started playing around with the new SSD standard – the NVMe M.2 SSD.

What is an NVMe M.2 SSD

The new way to increase your PCs performance is installing an NVMe M.2 SSD. NVMe stands for “Non-Volatile Memory Express” and is the newest protocol for accessing high-speed storage media and it has several advantages compared to legacy protocols. An NVMe drive is also an SSD, but instead of connecting it via a SATA III cable, it plugs directly into the motherboard via the M.2 PCIe slot, or into a traditional PCIe slot using an M.2 PCIe Adapter. The M.2 part refers to the form factor and how the drive connects to the motherboard. Surprisingly, the drive is only about the size of a stick of RAM. And while an SSD will drastically improve the performance over a traditional spinning hard drive, an NVMe M.2 is blazing fast in comparison. Think of it as SSD 2.0!

Here’s the high-level detail on the SPEC for each of the drive types available for home PC’s:

Obviously, the NVME SSD speeds blow the others away. But when deciding to add one or not, you also need to take the other major components of your computer into account. For example, if you have an older PC with a third-gen Core i3, 4 GB of RAM, and integrated graphics, you’re not going to be able to get the advantages of the speed the NVMe M.2 SSD drive provides. Additionally, given that the tech is still fairly new, you will also be paying a premium for an NVMe M.2 SSD drive vs. the legacy SATA III SSD drive. However, if what you’re looking for is the best, and you don’t mind spending a few extra bucks, the new NVMe M.2 SSD drives are the way to go.

If you want to upgrade, be sure to confirm your motherboard has the M.2 port or a spare PCIe slot for the adapter.  If you’re not sure what kind of slots you have open on your computer, refer to the manual or manufacturer’s site. Or, you can use the free tool Speccy from Piriform. Piriform is the team that created another very popular utility, CCleaner.


If you are looking to upgrade your current computer, adding an NVMe M.2 SSD will allow the full ability of your memory chips by blowing through the 600 MB/s limitations of SSD SATA cables. By plugging directly into the motherboard, an NVMe M.2 drive provides read/write speeds of up to 3,500 MB/s – which obviously blows away a typical SSD. If you have one installed in your computer, let us know how much of a performance boost you received. Or, if you haven’t installed one yet, read our guide on how to install one.
