Is formatting required during clean install from USB stick?

I bought a new SSD drive and used it to replace my old slow HDD in my laptop. I have just successfully installed windows 10 on it.

During the step shown in the picture below, I clicked on "New"

Which brought me to this step

From here, i just chose "Drive 0 Partition 4", clicked "Next", and the installation began.

Now here is my question, does it make a difference (or is it better) if I had chosen to format "Drive 0 Partition 4" first and then install? cuz my friend is saying that I should always format before installing Windows.

Thanks

There will be no difference, format is done automatically by Windows Setup. In fact you don't even need to partition the drive (unless you want to keep some space for dual-boot with another operating system), you just select the unallocated disk and Setup will do the rest. It will create all system partitions and the rest space will be formatted to NTFS for Windows.

Thanks~ That's good to know
