File Pathing question

Hardware Hub Storage
1

So I'm installing Win10 on a new SSD but I still want to access all my existing mechanical hard drives. When I install and boot into the SSD... Will I still be able to access all my files as normal?

I know this sounds silly, but I just want to do this right is all.

If you don't overwrite the data on your existing drives, you can still access the drives.
