This MacBook Pro comes 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 8TB of storage to deliver even more performance. (8TB available with M3 Max chip.)
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.
