Apple Vision Pro Model Reportedly Spotted With 1TB Storage
According to a report from iPhoneSoft, a source spotted an Apple Vision Pro model with 1TB of storage in the device's Settings app. While Apple has not officially announced the storage options for the Vision Pro, the fact that it will "start at" $3500 suggests that there will be multiple storage tiers available. The 1TB model would offer four times the storage of Meta's current highest storage options. Other VR headsets, such as HTC's Vive Focus 3 and Pico 4, offer lower storage options but have expandable storage through microSD slots. The increased storage in the Vision Pro would allow for higher quality textures, audio, and other assets in apps and games.
