Moving to an ADATA SSD can preserve your Windows installation, apps, and files if the clone includes the required boot partitions. Availability of bundled migration software varies by model and region, so verify the offer for your exact SSD rather than assuming every drive includes a license.
Use a system clone when you want Windows and its boot components but not every unrelated data partition. Use a full-disk clone when the target can hold the entire layout and you intend to carry all partitions. A smaller target must still hold the used data and required system partitions; sector-by-sector cloning usually needs a target at least as large as the source.
Step 1. Record the source and ADATA target models and capacities in Disk Management.
Step 2. Back up irreplaceable data separately. Save a BitLocker recovery key and suspend encryption protection as appropriate.
Step 3. Connect the ADATA SSD by its final internal interface or a compatible adapter. Check that Windows sees the correct capacity.
Step 4. Connect AC power and close other disk-intensive programs.
Warning: The target SSD will be overwritten. Copy any existing files off it and verify the disk model again before confirmation.
Step 1. Open Tools and utilities > Disk/Partition clone, then choose the disk-clone path.

Step 2. Select the old physical disk as source by model and capacity. Include its EFI/system and recovery partitions when migrating a bootable installation.

Step 3. Select the ADATA SSD as destination. Confirm the source and target are not reversed and that the destination holds the source's used space.

Step 4. On the preview, inspect partition order and unused space. Use Optimize for SSD if offered and appropriate for the target. Do not select sector-by-sector mode unless its size requirements are satisfied.

Step 5. Click Proceed, acknowledge the data-loss warning, then wait for completion and check the tool's final status.
Power off and place the ADATA SSD in its final slot. Temporarily disconnect the original if possible, then boot. Check Windows, applications, files, and partition capacity. If the boot fails, reinstall the original drive to preserve your fallback; investigate UEFI/legacy mismatch or missing boot partitions before retrying. Keep the source until the new disk has been proven reliable.
