Not only the processor and RAM, but also the smartphone’s data storage has a significant impact on performance. This is usually flash memory, which is now classified according to the UFS standard (Universal Flash Storage). This standard, in turn, is managed by the organization JEDEC, which has now officially approved UFS 4.0 – although the new generation is already in use.
In theory, UFS 4.0 is twice as fast as UFS 3.1
Without wanting (or being able) to go into too much technical detail about this very complicated matter, UFS 4.0 means doubling the potential data rate compared to UFS 3.1, which has represented the status quo on many high-end Android smartphones until now. . In concrete terms, this means a read rate of 5,800 MB/s – at least in theory.
Some manufacturers, such as Samsung, develop their own memory chips based on industry standards. Their first attempt at UFS 4.0 still achieves significantly higher speeds than its predecessor with peak read speeds of 4,200 MB/s and write speeds of 2,800 MB/s. Incidentally, the recently launched Samsung Galaxy Z Fold 4 is debuting new technology.
UFS 4.0 is more energy efficient
Other UFS 4.0 improvements include more than just better performance. Perhaps more important than ever these days is the highest possible energy efficiency, where UFS 4.0 certainly promises an improvement. In addition to “more secure data protection” and “reduced system latency,” UFS 4.0 is also backward compatible with UFS 3.1 and 3.0, according to the announcement. JEDEC.
