You forgot an important detail:
- MBR has only one partitioning table which is located on the first sector of the hard drive. If that track is wiped, your drive is considered unformatted, and data restoration must be read sector-by-sector.
- GPT has two partition tables which are located at sector 2 to 31 ( Primary GPT header ) and -31 to -2 ( Secondary GPT header ), where the sector 1 acts as a protective MBR for devices being unable to read GPT, and therefore see them as drive with "unknown" filesystem. If sectors 2 to 31 are wiped, they can be restored using the secondary header which in turn are an exact copy of the primary one, and vice versa.

I see this video is old. But you should all know that if you want to use any type of SAM (Smart access memory) for AMD or BAR for Nivida. It will require windows to read off of GPT mode. If your system is in MBR and fast access memory is enabled in BIOS, your GPU could black screen and SAM or BAR will not work. Faster Access memory is only available on Nivida 3000 series, or AMD 6000 series GPUs.

i have two drives, SSD+HDD, so my question is, with the MBR can i do 8 partition (4+4), or still 4?

"Limited to 4 Partitions". That's wrong. You can create unlimited logical partitions.

If i want to move everything(including OS) from my MBR C: Hard drive (using 416gb and total space is 913GB) to my new SanDisk 512gb SSD, would i be able to migrate it without a problem? Or would i need it to be a GPT hard disk? Thank you

GPT partitions make my systems goes buzzing sounds and game freezing especially game that is from early Access or alpha. Any fixes for this? MBR works just fine for me. So screw GPT craps.
