Compared to desktop computers, the speed of mobile phone storage chips has rapidly developed in the past two years. The once mainstream eMMC 4.5 has quickly evolved to the latest UFS 2.1. Currently, the highest speed of UFS 2.1 flash memory can reach 1166MB/s, while the theoretical maximum speed of mid-range eMMC 5.0 is 400MB/s;
Recently, there have been online revelations about UFS 3.0 and eMMC 5.2. UFS 3.0 will have a significant improvement over the current UFS 2.1, reaching a theoretical maximum speed of 2.4GB/s. However, according to industry insiders, UFS 3.0 is currently not very suitable for mobile devices in terms of power consumption control and requires further optimization;
Additionally, due to the limited production capacity of UFS flash memory chips, eMMC flash memory will still be the primary choice for some mid-range and low-end devices. Therefore, the next generation eMMC 5.2 standard has also emerged. However, the specific specifications of eMMC 5.2 are still unclear, and constrained by the inherent differences in technology, even the latest eMMC 5.2 will still have a gap in final read and write speeds compared to UFS 2.0. After all, besides read and write speeds, there are also differences in full duplex, half duplex, and serial parallel capabilities;
