The specific advantages of NVMe include:
1, the performance is improved several times;
2, the delay can be reduced by more than 50%;
3.NVMe PCIe SSD can provide 10 times the IOPs； of high-end enterprise SATA SSD;
4. Automatic power consumption state switching and dynamic energy consumption management function, greatly reducing power consumption;
5. Support the scalability of technological development in the next decade.
The flash memory that Apple uses now is actually TLC flash memory (and a small number of MLC). There is a flash door problem in the iPhone 6s era, which makes users very unhappy. However, the current facts prove that there is absolutely no need to worry about the service life of TLC flash memory. At least no iPhone has been scrapped because its service life has reached its limit.
The full name of UFS is universal flash memory, which is almost 2.5 times that of the fastest eMMC 5. X
However, in the face of Apple's NVMe, the flash memory performance of UFS 2. 1 lags behind, especially the reading speed, but the difference in writing speed is not great.
However, in actual use, we can't feel that the mobile phone after iPhone 6s is faster than the flagship Android phone, and some differences are actually caused by different operating systems. In terms of efficiency, Android is not as good as iOS.
In fact, it is very forward-looking for Apple to bring NVMe protocol to mobile terminals. Some analysts say that when the era of PC and mobile phone unification comes, more advanced protocols will inevitably become the same choice for PC and mobile phone platforms. Judging from the current situation, NVMe has this potential.
I believe that one day in the future, Android phones will gradually adopt this protocol. Of course, this is inseparable from the support of Android, and everything depends on Google.
Everyone who has a computer knows that the reading and writing speed of NVME protocol SSD is 3000M/s, while that of ordinary sata SSD is 500m/s. This UFS2. 1 is about the same as USB2.0 or 3.0, both of which are 300m/s..
Fast technology's answer is very detailed. Iphone uses a protocol similar to NVME, which is directly processed by CPU. It's the same as nvme, but it's a little different. It has its own patents and intellectual property rights. For example, nvme is directly processed by CPU, while UFS has to go through a special chip and then turn to CPU, which leads to a lot of slow speed!
Iphone's flash memory is also a ufs interface flash memory particle, which is the same as Android's ufs, but it works differently!
