Clean Install Windows 10

In my opinion, a 500 GB ssd is more than enough for windows and all your programs. If you buy a 1 TB ssd, use it for storage. You obviously have a lot of something or other on your 500 GB ssd taking up a lot of space.

The best method, in my opinion, is to create a disk image of windows and ALL the necessary partitions, and reimage them all to the 1 TB SSD.

But you need a place to store the image. So Luiz`s suggestion would be a better option if you feel comfortable doing that, we`re always here to help.

I just did this for a friend. Went from a 700GB HDD to a 1TB SSD. Cloned the HDD to the SSD (MBR/BIOS setup, no UEFI). No problem with disk ID duplicates.
After the cloning, there was almost 300GB unallocated so I use Minitool Partition Wizard to move the Recovery Partition to the end of the drive then expanded the C: partition to encompass the remaining unallocated space so the entire drive was now used.

I ran Macrium and Minitool from KYHI's Rescue ISO so I didn't actually boot the SSD until I was completely done working with it.

This was a HP DV7 laptop which has a place for two hard drives so I connected the HDD as the 2nd drive (added the necessary cable) and the SSD as the first drive. The HDD was a 5400 RPM slow spinner so it was very slow, took over two hours to do the cloning. I chose this method because I didn't have an external HDD with enough free space to hold the 500-600GB backup image. Also the DV7 only has USB 2.0 ports so it would have taken even longer to do the backup to an external HDD.

All worked perfect, just took a lot of time because of the slow HDD.

Are you having issues with your current Windows installation?
If it's not the case, just clone the current drive into the new one.
Use Macrium Reflect

Using Reflect is a good option but I prefer to image the existing installation to another drive, install the new SSD, boot the Reflect recovery drive and restore the image to the new SSD

I do too but I explained why I had to clone this time and the fact that it worked okay, so no reason to be afraid of it or avoid using it when necessary.

The only concern with cloning is you can end up with both drives having the same ID then if you are going to leave both drives installed you need to do something about that. You can use diskpart or Disk Management to fix the problem. My setup was BIOS/MBR and I didn't end up with a duplicate disk IDs for whatever reason (maybe BIOS/MBR is not susceptible to the problem).

Modify the Disk Signature using Disk Management

You can follow these steps to do the job:

Press Windows + R to open Run.
Type diskmgmt.msc and press Enter to open Disk Management.
Right-click on the offline disk and select Online from the popup menu.

Then, Windows will assign a new disk signature for the drive..

You're welcome. I found that while researching how to use diskpart to fix duplicate disk ids.
