Now it is time to change HDD to SSD. I want to keep the system, data, everything on the HDD.
The original HDD on XPS 15 is Hard Drive 750GB 7200 RPM SATA Hard Drive.
The very first step is to clean my laptop.
Remove some useless programs and movies. Move one of the users’ data to NAS. Delete this user. Just keep one user, which is my daughter. The purpose of this step is to reduce the data to less than 240GB.
The second step. Install SSD into Nexstar External Enclosure.
The third step. Clone the HDD to SSD.
I connect the enclosure to my laptop through USB cable. Install the cloning software, or migration software, which is shipping with SSD.
When the cloning process finished, turn off the laptop. disconnect all cable and power.
