For a home user, a 512 GB drive should be more than sufficient and you could even consider this to be a lot of internal storage. However, it depends on how much storage space you think that you will need for your laptop.  If you intend to store large files such as games, high-resolution images, and videos, a 512 GB drive may not be large enough for your laptop. However, you can do other things, such as a USB external drive for additional space or using cloud storage services.  The difference in price between a 512 GB HDD and a 1 TB HDD is not that much, so we recommend choosing the larger drive if you are in doubt. However, SSD prices are a lot higher, so this may not be an option for you.
