The press release refers to it as:

UltraSpace storage expansion is a patented Xiaomi technology implemented on Xiaomi 14 Series.² It makes use of available UFS memory to expand available storage beyond original capacity. This technology allows the 256GB version of Xiaomi 14 Pro's storage to be expanded by 8GB, while the 512GB version of Xiaomi 14 and Xiaomi 14 Pro's storage can be extended by 16GB,¹ allowing users more storage space to store more applications, photos, videos, and other data without unnecessarily increasing their hardware costs.

I'm not clear whether this refers to space for firmware or cache or both.

In the launch video (around 2:04:00) I would summarise what Lei Jun said as:

  • During writing HyperOS their engineers made a "discovery" that the UFS storage chips have 10GB+ storage reserved for "性能的优化" (Performance optimizations, so likely refers to UFS cache?)

  • They apparently optimised this to use much less space and so freeing up 8/16GB on their 256/512GB storage models, giving them "264/528GB" of actual usable storage.

  • Also interesting it doesn't apply to the 1TB models, in which case either the full cache amount is more useful or the extra % storage is negligible.

This would be the first time we've seen a branch do this kind of optimisation.

Now that would be innovative. There are probably kids today who have never seen a phone with expandable storage or removable batteries.

Because many only have seen Apples ~~scam~~ devices and nothing else.
