Hello. I have an HP laptop - HP Probook 455 G7. I upgraded the main NVMe M.2 SSD to a 512GB some time ago with no issues whatsoever.
It seems that this is the maximum size NVMe M.2 SSD that will fit this model (according to the HP documentation). I do want to fit something bigger. Like a 2TB NVMe M.2 SSD.
Is this possible at all to do with this laptop and can someone who had actually done such an upgrade please confirm if this would work?
All the Windows updates on Windows Pro 11 are applied. As are all the relevant HP Probook G7 updates. BIOS and so on.
The laptop is compatible with Windows 11. I look forward to hearing from you. Thank you.
Solved! Go to Solution.

Hi:
The drive capacities are just what HP offered in the model series, not the maximum capacity supported.
The Crucial memory/SSD report for your notebook indicates it will support NVMe SSD's up to 4 TB.

I don't see any reason why a 2 TB drive wouldn't work.

Hi:
All the major SSD manufacturers normally supply free cloning software.
For example if you purchase a Samsung SSD you can download the free Samsung Magician software which is a utility that also can clone drives.

If you want to clone a drive remember to buy a USB-C/USB3 to NVMe SSD enclosure to put the drive you want to clone to inside as your notebook does not have two NVMe slots.
Something like this:
For any drive, you can use the Macrium Reflect Free software which you can download from the link below.

Truly appreciate it Paul.
Just one more thing. The NVMe drive I want to clone is the main one in my laptop and it's in use. To clone it means buying an enclosure (like you've said). That I understand.
What's the best way to clone it? Seeing it's in use and Windows boots from it.
I understand that I will need to put the drive I want to clone inside the new SSD enclosure. That then connects to the laptop to clone?
I think I need to install the blank new NVMe drive inside the laptop. But how will the cloning work if the new drive is blank and the one that is being cloned needs Windows to run the cloning software on?
Am i missing something here or a step or two? Please solve my confusion Paul.
Thanks. Mandeep 🙂

Hi, Mandeep:
I don't know how the cloning software works exactly but I do know that you don't need to remove the current drive to clone to a new one.
I create system images all the time using Macrium Reflect and they work fine to restore the drive with an image if I have an issue.
Nope, you can install the new drive in the enclosure and clone the running drive's contents to it.
