What is M.2 and NVMe? This article will explain the differences.

When searching for "SSD" online, numerous related queries emerge, with two prominent ones being M.2 SSD and NVMe SSD. At this point, you might assume that M.2 and NVMe are distinct types of solid-state drives (SSDs) and wonder which one is superior or more suitable for your needs. However, upon reading this article attentively, you might realize that M.2 and NVMe are not SSD categories themselves. So, what do they represent, and which SSD should you opt for? Fear not, as we will clarify these concepts step by step.

M.2 vs NVMe? Are These Two Terms Comparable?

At the outset of this article, let me assist you in understanding the distinction between M.2 and NVMe. Actually, these two terms are not comparable since M.2 refers to a type of SSD interface, whereas NVMe is a protocol for SSDs. It's akin to comparing a connector with a storage device and wondering which one to choose – there isn't a valid comparison to be made.

The older SSD, which we can refer to as the first generation, is essentially a SATA SSD. This means it utilizes a SATA interface for connectivity. Of course, there's also the M.2 SSD that features an M.2 connector. However, in terms of performance, there isn't much difference between a SATA SSD and an M.2 SSD. The second generation of SSDs is typically referred to as NVMe SSDs. These exclusively use the M.2 connector, hence they are often called NVMe M.2 SSDs.

When searching for "M.2 vs NVMe," you're essentially asking which one to choose between a SATA/M.2 SSD and an NVMe M.2 SSD. In the following section, you'll learn which option is better suited for your needs.

NVMe vs SSD: Discover the Key Differences in a Single Table

In this table, we have enumerated six factors that influence users' choices when selecting an SSD. Examine this table to discern the differences.

As per the table, it is evident that NVMe SSD surpasses SATA SSD in multiple aspects. NVMe SSD employs a more advanced protocol, boasts a higher transfer rate, and achieves faster speeds. Generally speaking, NVMe SSD is a more recommended choice.

Though NVMe SSDs outperform in every way, SATA SSDs maintain a considerable market share largely because many computers' motherboards don't have M.2 slots. With an M.2 slot, users can connect an NVMe SSD directly to the motherboard, eliminating the need for cables during installation. In contrast, installing a SATA SSD requires two cables: a SATA cable to connect the SSD to the SATA interface and a power cable to supply electricity to the SSD.

So, let's draw a conclusion. If your motherboard features an M.2 connector, we recommend opting for an NVMe SSD. If you previously utilized an HDD or your motherboard solely has a SATA connector, it's advisable to choose a SATA SSD.

NVMe vs SSD: Which Is Faster?

What sets these two types of hard drives apart, and how does NVMe outperform SSDs? In this article, we will comprehensively discuss NVMe SSD and standard SSD to assist you in making an informed choice.

How to Clone from an SSD to an NVMe SSD?

When upgrading the hard drive, nobody wants to experience data loss or have to start from scratch, which is why it's always advised to clone the hard drive. Cloning one disk to another essentially creates an exact replica of the source hard drive. This means all your files, folders, applications, and configuration settings will be present on the target disk. You can also boot from a cloned drive, provided you have cloned the system partition.

Now, you need to select a cloning tool. We recommend using Todo Backup. As the name implies, it offers backup functions, but it also excels in cloning tasks. Whether you're upgrading from an HDD to an SSD or migrating your Windows OS to a new SSD, Todo Backup proves to be dependable and user-friendly. Additionally, this tool allows you to back up your crucial files to the cloud or an external hard drive, safeguarding against unexpected data loss. As they say, prevention is better than cure.

If you're ready, download the tool Todo Backup and find out what steps are required to clone from an SSD to an NVMe SSD.

Step 1. Connect the New Second Hard Drive to the PC

Preparations before cloning begin:

1. To connect the target disk to your PC, you might require a screwdriver, a Power Splitter Adapter Cable, a SATA cable, or a USB to SATA adapter. 
2. Ensure that the target HDD/SSD has a capacity equal to or greater than the used space on the old drive.
3. Verify if the new disk's format matches the old disk's. If not, Initialize a new HDD/SSD to MBR or GPT.
4. Download a Disk Cloning Utility – such as Todo Backup.

Todo Backup is a cloning software that incorporates multiple functionalities, such as disk cloning, system backup, file backup, etc. In the realm of disk cloning, this tool distinguishes itself with the following features:

• Supports system/disk cloning, backup, restoration, and system transfer.
• Caters to various disk cloning needs, such as upgrading to a larger hard drive or cloning an operating system.
• Boasts the highest success rate for disk cloning compared to similar products in the market.
• Comprehensive support for all types of disks, including IDE, EIDE, SATA, ESATA, ATA, SCSI, iSCSI, and USB 1.0/2.0/3.0.
• Facilitates cloning of both basic/dynamic disks and MBR/GPT disks.

Step 2. Step-by-Step Guide

System Clone: Select System Clone > choose the target disk > click Next to begin. In Advanced options, you can opt for Create a portable Windows USB drive to clone the system to a USB drive.

Disk/Partition Clone: Choose Clone > Select the source disk or partition > Select the target disk > Click Next to start.

Step 3. Boot from the Cloned Hard Drive

Case 1. If you wish to retain both the old disk and the new disk

• Restart your PC and press F2 (or F8, F10, DEL, depending on the system) to access the BIOS settings.
• In the Boot section, choose the new HDD or SSD as the primary boot device.
• Exit the BIOS and let the computer restart normally.

Case 2: If you want to keep only the new disk

1. Unplug the old disk and ensure the new disk is properly connected.
2. Attach the new disk and verify that it is detected by the computer.
3. Restart your computer.

Bottom line.

In summary, M.2 refers to the form factor of solid state drives (SSDs), while NVMe is a specific protocol for high-speed SSDs. NVMe-based SSDs outperform SATA SSDs in terms of speed. However, if your motherboard does not support the M.2 interface, it is advisable to opt for a SATA SSD instead.
