I am using Acronis software to make a full backup of my PC and storing the backups made into a WD Black 1TB hard disk and it takes about 9 hours to complete making the full backup. (I tried 2 different WD Black 1TB and both took about 9 hours)

I then tried using Acronis software to make a full backup of my PC and storing the backups made into a WD Green 4TB hard disk and it takes about 4 hours to complete making the full backup.

Nothing else is changed. Except the hard disk. Both are connected to the same internal hard disk slot.

Does more empty space make backups process faster?

Why is making backup and storing into WD Green 4TB almost 2 times faster than WD Black 1TB?

Thanks

 

ADD INFO: The only difference is the 1TB WD Black is MBR , the 4TB WD Green is GPT

 

Short version: I put in 1TB WD black into internal hard disk slot A. I then make a full backup of my whole PC, it takes 9 hours to complete. I then remove the 1TB WD black from the internal hard disk slot A. I then insert 4TB WD green into the same internal hard disk slot A. I then make a full backup of my whole PC, it takes 4 hours to complete.
