M.2 NVMe drives have become the default upgrade path for both desktops and laptops, and the current wave of PCIe 5.0 sticks pushed 4 TB into affordable territory. That is turning a lot of “should I upgrade?” browsers into buyers, and pushing everyone to the same next question: how do we clone a booting Windows install onto a new NVMe stick without the system refusing to POST afterwards? Seven apps for M.2 NVMe drive cloning on desktop below cover the paths that actually work in 2026, tested on a real 2 TB upgrade from a Samsung 970 EVO to a WD Black SN850X on a Windows 11 machine with Secure Boot on.
The benchmark was blunt: install the app, clone the boot drive, swap the sticks, and see whether Windows booted at first attempt. All seven passed that test with the right options set. The ranking below is about how much friction each one added to get there.
What to look for in an NVMe cloning app
Five things separated the apps that “just worked” from the ones that made the swap painful:
- Sector-intelligent vs sector-by-sector. Copying only used blocks is orders of magnitude faster. Every serious app now offers this; only pick sector-by-sector when the source has bad sectors and needs a raw image.
- UEFI/GPT support with proper alignment. NVMe partitions have to align to 1 MB boundaries. Any app that dumps partitions raw without re-aligning to the new drive geometry causes performance loss.
- Secure Boot survival. The clone must preserve the EFI system partition and its bootloader signatures. Modern apps handle this; some older forks do not.
- Live vs offline clone. Cloning the running Windows drive is convenient. Booting to a WinPE or Linux image and cloning from there is safer for the boot loader.
- Larger-to-smaller cloning. Sometimes the new drive is smaller. Some apps refuse; some resize partitions on the fly.

The apps
1. Rescuezilla, the top pick for a one-time Windows upgrade
Rescuezilla is the app to reach for on a first NVMe swap. It is Clonezilla with a real graphical front end, distributed as a live USB Ubuntu image. Boot it, plug in the new NVMe on a USB-C M.2 enclosure, click “Clone,” pick source and destination, and walk away. Under the hood it is still using Clonezilla’s proven sector-intelligent engine, so only used blocks get copied and the 2 TB clone finishes in the time it takes to make lunch.
For anyone who has never cloned a drive before, Rescuezilla is the fastest path to a working system.
Where it falls short: the live USB requires a spare USB stick and 15 minutes to build. Advanced partition tweaks are hidden.
Pricing:
- Free, open-source.
Platforms: Linux live USB (works with Windows, macOS, and Linux source drives).
Bottom line: the top pick for a one-time NVMe upgrade on any OS.
2. Clonezilla, the CLI original
Clonezilla is the older sibling. Same engine, same reliability, same live USB distribution, but text-mode dialogs instead of a mouse-driven flow. For anyone comfortable in the terminal it is the fastest option here: the wizard walks in a straight line and there is no rendering to slow it down. Sysadmins who image machines regularly still keep Clonezilla on a bootable USB.
Batch mode with saved configuration files lets one Clonezilla USB serve a whole fleet.
Where it falls short: the UI is a wall of text. First-time users often skip the wrong option and clone into the wrong drive.
Pricing:
- Free, open-source.
Platforms: Linux live USB.
Download: Site
Bottom line: the pick for anyone who prefers a text wizard to a mouse-driven GUI.
3. Macrium Reflect, the Windows heavyweight
Macrium Reflect is the reference commercial Windows cloning app, and it earned that reputation. Rapid Delta Clone means only changed blocks copy on subsequent operations, so re-cloning a working drive completes in minutes instead of hours. The interface is dense but discoverable. Secure Boot, GPT/UEFI, and larger-to-smaller cloning all work without workarounds. Macrium retired the long-running Free tier a couple of years back, and the current entry point is the Home Edition.
For anyone who images the same machine regularly (a work laptop, a family PC), the Rapid Delta clone speed pays for the paid tier in one weekend.
Where it falls short: the free tier is gone. The one-off Home price is fair but real.
Pricing:
- Trial: 30 days.
- Paid: Home Edition, roughly the cost of a mid-tier keyboard as a one-off.
Platforms: Windows.
Download: Site
Bottom line: the pick when Windows cloning is a recurring task, not a one-time swap.
4. EaseUS Disk Copy, the mouse-first Windows path
EaseUS Disk Copy is the point-and-click Windows app for anyone who wants the whole thing to feel like a printer wizard. Pick source, pick destination, click Proceed, done. It supports sector-by-sector cloning when a bad-block source demands it, handles NVMe cleanly, and preserves the EFI system partition.
The trade-off is the subscription model, and the aggressive upsell during install.
Where it falls short: subscription-only pricing, aggressive marketing prompts.
Pricing:
- Trial: limited.
- Paid: annual subscription in the mid-two-figure range.
Platforms: Windows.
Download: Site
Bottom line: the pick when the friction budget is zero and the annual cost is fine.
5. AOMEI Backupper, the bundled imaging suite
AOMEI Backupper puts the clone tool inside a broader imaging and backup suite, which matters when the clone is the last step of a bigger workflow (image the old drive, upgrade Windows, clone to the new NVMe). The Standard tier is free and handles the basic NVMe clone; the Professional tier adds Universal Restore (cloning to different hardware) and command-line automation.
The UI is dated but reliable.
Where it falls short: the free tier holds back the useful upgrades. Universal Restore is worth the money if the target hardware is different.
Pricing:
- Free: AOMEI Backupper Standard.
- Paid: Professional, annual subscription in the mid-two-figure range.
Platforms: Windows.
Download: Site
Bottom line: the pick when the clone is part of a broader Windows imaging routine.
6. Samsung Data Migration, the vendor tool
Samsung Data Migration is the free vendor app that comes with any Samsung NVMe SSD, and it is worth using when the destination drive is Samsung. It only clones onto a Samsung target, but that constraint is what makes it fast: Data Migration knows the target’s DRAM cache behavior and pre-conditions the write pattern. On a Samsung 990 Pro target the clone runs at the drive’s full sustained write throughput.
The 2026 UI reshuffle finally hides the “trial expired” nag that older versions carried after the migration completed.
Where it falls short: Samsung-target only. Refuses non-Samsung destination drives.
Pricing:
- Free.
Platforms: Windows (and Samsung Magician on macOS for firmware, though not for cloning).
Download: Site
Bottom line: the pick when the destination drive is a Samsung SSD.
7. dd (coreutils), the Linux and macOS scripted path
dd is the classic Unix block copier, and it is on this list because for anyone comfortable at a Linux or macOS terminal, dd plus a status pipe (pv) is still the shortest path to a raw NVMe clone. It does not do sector-intelligent copying (every byte gets moved), so it is not the fastest option, but there is no third-party tool to install and every recovery live USB has it. Pair it with fsck and partclone for a lightweight NVMe clone workflow.
For headless servers where installing a GUI is not on the table, dd is the answer.
Where it falls short: no partition awareness, no intelligent skipping. A misplaced argument cheerfully destroys the wrong drive.
Pricing:
- Free, part of coreutils.
Platforms: Linux, macOS.
Download: already installed on every Linux distro and macOS release.
Bottom line: the pick when the environment is a headless Linux box and installing anything larger is not welcome.
How to pick the right one
- If this is a first-time Windows NVMe upgrade: Rescuezilla. It is the shortest working path.
- If Windows cloning is a recurring task: Macrium Reflect. Rapid Delta Clone is worth the paid tier.
- If the destination is a Samsung SSD: Samsung Data Migration, free from Samsung.
- If the workflow needs image + clone + universal restore: AOMEI Backupper Professional.
- If mouse-first is the priority and subscription is fine: EaseUS Disk Copy.
- If comfort at a text-mode wizard is fine: Clonezilla, the same engine as Rescuezilla without the mouse.
- If the environment is headless Linux or macOS: dd with pv for progress.
FAQ
Do I need to boot from a live USB to clone the Windows drive?
Not always. Macrium Reflect and EaseUS Disk Copy can clone the live Windows drive because they use Volume Shadow Copy to snapshot the source. But cloning from a live USB (Rescuezilla, Clonezilla) is safer because nothing is writing to the source during the copy.
Will Windows boot after the clone or do I need to fix Secure Boot?
Every app on this list preserves the EFI system partition and the bootloader. Secure Boot survives on all of them. If the clone fails to boot, the fix is usually to run “bootrec /rebuildbcd” from a Windows recovery USB, not to redo the clone.
Can I clone a bigger NVMe drive to a smaller one?
Yes, as long as the used data fits on the smaller target. Macrium Reflect and AOMEI Backupper resize partitions during the clone. Clonezilla and Rescuezilla require some manual resize before cloning; dd flatly refuses.
Is Samsung Data Migration really enough, or should I use Macrium?
If the destination is a Samsung SSD, Data Migration is the right answer: it is free, it is fast, and it knows the target’s DRAM behavior. Macrium is the answer for non-Samsung destinations and for anyone who clones regularly.
What is the fastest way to clone a 2 TB NVMe drive?
Macrium Reflect with Rapid Delta Clone on the second and subsequent clone operations. First clone is bounded by the drive write speed regardless of app.
