The Apple Studio Display and ‌Studio Display‌ XDR are equipped with A19 and A19 Pro chips, respectively, and each display has 128GB of internal NAND storage.

With A-series chips, the Studio Displays run an iOS-based operating system, which is what the internal storage space is used for. The A19 and A19 Pro handle camera processing for the Center Stage camera, color calibration, USB and Thunderbolt device management, spatial audio, and more.

Storage space is necessary for the existing software, downloading new firmware updates over time, and perhaps for diagnostics, but the storage is not used for user-facing features.

The prior-generation ‌Studio Display‌ had 64GB of storage, so the new displays have double the capacity. Apple likely found it more affordable to use existing NAND storage from its iPhone supply chain rather than to invest in smaller modules with less storage. Most of the 128GB is probably unnecessary.

Along with 128GB of storage, the ‌Studio Display‌ has 8GB RAM and the ‌Studio Display‌ XDR has 12GB RAM. The new displays launched today, and are now available for purchase from the online Apple Store and Apple retail locations.
