What fraction of the market will use over 64GB? I&#x27;m guessing it is only a tiny fraction.<p>Ignoring that, let&#x27;s assume there is a significant market there. What fraction of that market would be able to move their data from their old phone to their new phone? Again, I would guess a tiny fraction. Syncing 512GB in a reasonable time frame would likely require a direct computer connection at USB 3 speed or thereabouts.<p>So, your best bet likely is a phone that allows plugging in a 512 GB flash module.
