Okay not limitless but close enough. I have this in a 32GB phone and combined, that's quite a bit of available storage. I have tons of photos, music, and entire seasons of TV shows.It's great to never get a warning about having low storage. I can take the max resolution photo option with my phone and shoot 4k videos without having to worry about running out of space.It's also speedy at transferring files to and from my laptop.
