The UltraSpace storage expansion feature is not available on all models of the Xiaomi 14 series. Specifically, it is only implemented in certain configurations:
- 256GB Model of Xiaomi 14 Pro: This model benefits from an additional 8GB of virtual storage, effectively increasing its usable capacity to 264GB.
- 512GB Models of Xiaomi 14 and Xiaomi 14 Pro: These models receive a larger expansion of 16GB, bringing their total usable storage to 528GB.
Notably, the UltraSpace feature is not available on the standard 256GB Xiaomi 14 model, nor does it extend to other variants like the 1TB model. The technology utilizes a portion of the UFS storage that is typically reserved for Over-Provisioning (OP), optimizing it to provide extra space without requiring additional hardware[1][2][3].
This selective availability raises questions about why some models do not support this technology, but it appears to be tied to specific hardware configurations and software optimizations that Xiaomi has implemented for these particular models[4].
