How to Transfer All Data from One SSD to Another

The right transfer method depends on what “all data” means. Documents can be copied as files; moving Windows, installed applications, hidden boot partitions, and settings calls for a whole-disk clone or a fresh setup.

Choose file copy or disk clone

For a secondary data SSD, connect both drives and copy selected folders in File Explorer. Check permissions and hidden folders if needed. This is usually sufficient for photos and projects, but not for a bootable Windows installation or applications that rely on registry entries.

For a boot-drive replacement, clone the entire source disk. Make sure the target's usable space can hold all selected partitions and used data. A larger target may have unallocated space afterward.

Prepare both SSDs

1. Confirm the interfaces and adapter support: an M.2 SATA enclosure will not necessarily work with an NVMe SSD.
2. Back up needed files from the target because cloning overwrites it. Check both drives by model and capacity, not letter alone.
3. Record BitLocker recovery information and keep stable power. Pause heavy writes to the source while cloning.

Test the result before wiping the source

If it was a system clone, shut down, boot with only the new SSD connected when practical, and verify Windows Boot Manager, apps, and files. If it was a file copy, compare folder counts and open representative files. Keep the original SSD untouched until the transfer has passed those checks.

Frequently Asked Questions

Can I use copy and paste for a boot drive? No. A file copy does not recreate all boot partitions or the disk's boot configuration.

Can I clone to a smaller SSD? Only if used data and required partitions fit and the cloning mode supports the layout.

Conclusion

Copy files for a data-only move; clone the disk for a Windows migration. Verify the new SSD before reusing the old one.
