A 1TB SSD is more than enough for most people. Even if you have a lot of music, photos, and videos, you're unlikely to fill up a 1TB drive. If you do find yourself running low on storage, you can always delete some files or move them to an external drive. However, if you have a large movie or video collection, you may want to consider getting a 2TB SSD. Otherwise, a 1TB SSD should be plenty of storage for most people.
