How to Clone NVMe SSD to SATA SSD

Cloning your NVMe SSD to a SATA SSD creates an exact copy of your operating system, applications, and files on the new drive, so you can swap it in without reinstalling Windows or losing data. This guide covers the entire process, from choosing the right cloning software to verifying the clone works. Before starting, back up any critical files and ensure the SATA SSD has at least as much capacity as the used space on your NVMe drive.

What You’ll Need

NVMe SSD (source drive) with the data you want to clone.
SATA SSD (target drive) – must be equal or larger in capacity than the used space on the source.
A free SATA port and power connector on your motherboard, or a USB-to-SATA adapter for external connection.
Cloning software – free options like Macrium Reflect Free, Clonezilla, or Samsung Data Migration (if your source is Samsung) work well.
A Phillips screwdriver if you need to install the SATA SSD inside your PC.
Optional: a SATA data cable if your motherboard didn’t come with one.

Step-by-Step

Prepare the target SATA SSD. If it’s new, no formatting is needed – cloning will overwrite it. If it has data you want to keep, back it up elsewhere first.
Connect the SATA SSD. If you’re cloning to an internal drive, shut down your PC, install the SATA SSD into a free bay, connect the SATA data cable to the motherboard and the power cable from the PSU. If you’re using an external adapter, plug it in via USB.
Boot your PC and download cloning software. For Windows, Macrium Reflect Free is a reliable choice. Download and install it. If your NVMe is a Samsung, you can use Samsung Data Migration instead.
Open the cloning software and select the source drive. In Macrium Reflect, you’ll see a list of drives. Your NVMe SSD will be listed as Disk 1 or similar. Click on it to select it.
Select “Clone this disk”. This option is usually in the left-hand menu or under the disk’s context menu. Click it to start the cloning wizard.
Choose the target disk. In the wizard, select your SATA SSD as the destination. Important: Double-check you’re selecting the correct disk – cloning to the wrong drive will erase it.
Review the partition layout. The software will show how the source partitions will be copied. If the target is smaller than the source, you may need to shrink partitions. Most tools handle this automatically if the target is large enough for the used space. If not, uncheck the “Copy partitions” option and manually resize.
Start the clone. Click “Copy” or “Finish” to begin. The process can take anywhere from a few minutes to over an hour, depending on the amount of data and drive speeds. Do not interrupt it.
Wait for completion. The software will show a progress bar. Once it says “Complete”, shut down your PC.
Swap the drives (optional). If you want to replace your NVMe with the SATA SSD as your main drive, remove the NVMe and install the SATA SSD in its place (or just leave the SATA SSD connected and change boot order). If you’re keeping both, you can boot from the SATA SSD by changing the boot order in BIOS.
Boot from the cloned drive. Turn on your PC and enter the BIOS (usually by pressing Del or F2 during startup). Change the boot order to prioritize the SATA SSD. Save and exit. Your system should boot into Windows with all your files and settings intact.
Verify the clone. Once booted, open Disk Management (right-click Start > Disk Management) and confirm the SATA SSD shows the correct partitions. Check that your files are accessible.

Common Mistakes

Choosing the wrong target disk. This is the most critical error – it will erase the target drive. Always double-check the disk numbers and sizes.
Not enough space on the target. The SATA SSD must have enough capacity for the used space on the NVMe. If it’s smaller, the clone will fail or you’ll need to shrink partitions.
Interrupting the cloning process. Unplugging the drive or shutting down mid-clone can corrupt both the source and target.
Forgetting to change boot order. If you don’t change the boot order, your PC will still boot from the old NVMe, and you might think the clone failed.
Using a USB adapter that’s too slow. If cloning via USB, use USB 3.0 or higher for reasonable speeds.

Tips

If your NVMe has more used space than the SATA SSD’s capacity, free up space by deleting unnecessary files or using a disk cleanup tool before cloning.
Some cloning tools allow you to resize partitions during the clone – use this if the target is smaller than the source.
After cloning, keep the original NVMe untouched for a few days until you’re sure the clone works perfectly.
If you’re cloning to a SATA SSD for performance reasons, note that SATA SSDs are slower than NVMe, so expect slightly longer boot times and load times.
Use a SATA data cable that is securely connected – loose cables can cause intermittent failures.

Troubleshooting

Clone fails with “disk too small” error. This means the target’s capacity is less than the source’s used space. Free up space on the source or use a larger target drive. Some tools let you exclude certain partitions (like recovery partitions) to fit.
PC won’t boot from the cloned drive. Check BIOS boot order – ensure the SATA SSD is first. If it still doesn’t boot, try disconnecting the NVMe temporarily to force the system to use the SATA SSD. If it boots then, you may need to adjust boot settings.
The cloned drive shows up but is not bootable. This can happen if the clone didn’t copy the boot partition correctly. Re-run the clone and ensure you’re cloning the entire disk, not just the C: partition.
Windows activation issues. Cloning a drive can sometimes cause Windows to deactivate. This is usually a hardware change detection. You can reactivate via Settings > Update & Security > Activation. If it fails, contact Microsoft support.
Data on the target is missing after boot. If you booted from the old NVMe, the cloned SATA SSD might be offline. Open Disk Management and assign it a drive letter.

Frequently Asked Questions

Can I clone a larger NVMe to a smaller SATA SSD?

Yes, if the used space on the NVMe is less than the SATA SSD’s capacity. The cloning software will shrink the partitions automatically. If the used space exceeds the target, you’ll need to free up space first.

Do I need to format the SATA SSD before cloning?

No, cloning software will overwrite the target drive completely. Any existing data will be lost, so make sure there’s nothing you need.

Will cloning copy my Windows license?

Yes, the clone is an exact copy, including your Windows activation. However, if Windows detects a significant hardware change (like a different motherboard), it may require reactivation.

How long does cloning take?

It depends on the amount of data and the speed of both drives. A typical 500GB clone can take 15-30 minutes with a direct SATA connection. Cloning via USB can be slower.

Can I use the SATA SSD as a secondary drive after cloning?

Yes, you can. Just don’t change the boot order, and the SATA SSD will appear as another drive. You can then format it if you don’t need the clone.

Is it better to clone or do a fresh install?

Cloning is faster and preserves your exact setup, but it also copies any underlying issues. A fresh install is cleaner but requires reinstalling all your programs and settings. For most users, cloning is the easiest way to upgrade.
