This MacBook Pro comes standard with 512GB of SSD storage,¹ giving you fast access to your documents, photos, music, and apps, as well as extensive video libraries and large data files.
For demanding workflows with large files, you can configure your MacBook Pro with up to 2TB of storage to deliver even more performance.
Note: Storage is not user accessible. If you think you’ll need more storage capacity in the future, consider configuring to a higher capacity.
1.1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less.
