Cloning HDD to SSD on Mac Big Sur

Mac users who have opted for Big Sur as their system will likely have experienced much faster boot speeds and improved performance in general. This is largely due to Big Sur’s use of the APFS (Apple File System) and advanced hardware optimization. As Big Sur continues to evolve and improve, many Mac users have begun to look into ways to further increase their system performance. One of the most popular methods to do this is to clone the internal hard drive to an external or internal solid-state drive (SSD). This article will cover the basics of cloning a hard drive to an SSD on Mac Big Sur and provide helpful tips for a successful cloning process.

What is Cloning?

Cloning essentially allows data to be transferred from one drive to another and involves taking a complete copy of the source drive and replicating it onto the destination drive. This process is typically used by engineers and IT personnel to save time when preparing a large number of systems for deployment. This process not only saves time, but also helps ensure consistency across those systems.

What You Need to Consider Before Cloning a Hard Drive to SSD on Mac Big Sur

Before attempting to clone a hard drive to an SSD on Mac Big Sur, there are a few essential factors that a user must consider. The most important factor is the destination drive. In order to successfully clone a hard drive to an SSD, the destination drive must meet the following criteria:

  • It must be using the same file system as the source drive.
  • It must have the same capacity or more than the source drive.
  • It should have a compatible form factor with the Mac’s internal drive slot.

If the destination drive does not meet these criteria, the cloning operation may be unsuccessful or, even worse, cause data corruption.

How Can I Clone a Hard Drive to an SSD on Mac Big Sur?

Cloning a hard drive to an SSD on Mac Big Sur is actually very simple, thanks to Apple’s built-in cloning tool. This tool, “Disk Utility,” can be found in the Mac’s “Utilities” folder within the “Applications” folder. With Disk Utility, users can conveniently clone their hard drive onto an external or internal SSD.

The First Step: Prepare Destination Drive

Before attempting the cloning process, users should ensure that their target drive is properly connected to the Mac. For external SSDs, this may require the use of an external SATA cable, which can be purchased from most electronics stores. Once connected, users can initialize the disk by launching Disk Utility and selecting “Initialize” from the Target Disk tab. After initializing the disk, users can proceed with the cloning process.

The Second Step: Begin Cloning Process

Cloning a hard drive to an SSD is fairly straightforward with macOS Big Sur. To begin the cloning process, users must launch Disk Utility and select the source hard drive and the target SSD. To start the cloning process, users must select “Clone” from the “Edit” drop-down menu and follow the simple on-screen instructions. The cloning process may take some time, depending on the size of the hard drive and the speed of the connection between the source drive and the Mac.

The Third Step: Verify and Re-name the Clone

Once the cloning process is complete, users should verify that the cloned drive has been successfully created by launching Disk Utility and selecting the target disk. If the cloning process was successful, the source and target disks should have identical details. Mac users may also want to rename the target disk for easy identification.


Cloning a hard drive to an SSD on Mac Big Sur is a great way to increase performance and improve the reliability of the system. Although the process itself is fairly simple and can be completed using the macOS built-in Disk Utility tool, users must take care to ensure their destination drive meets the criteria required for a successful cloning operation. With attentive care and following the above steps, Mac users should be able to experience numerous performance improvements after a successful cloning operation.
