What to Prepare When Your PC Has a Single Slot

Nowadays, most laptops come with only one M.2 slot to install an SSD. To clone the NVME M.2 SSD to another larger SSD, two slots are required generally. If your PC only has one slot, what should you do in such a situation?

There’s still a way out. Here, you can try two options:

  1. Prepare an M.2 to USB converter/adapter or M.2 SSD enclosure to connect your second M.2 drive to the computer. Then, you can migrate everything to the target disk via cloning.
  2. If you don’t have an adapter, you can create a disk backup for the original M.2 SSD, make a bootable USB drive, replace the old NVME M.2 SSD with the new M.2 drive, and restore the system to the new SSD.

The second method doesn’t involve cloning but backup & recovery. If you concern about “how to clone OS from M.2 SSD to M.2 SSD with only one M.2 slot” or “how to clone M.2 SSD with a single slot” using the first way, continue reading to find a step-by-step guide.
