Teardown reveals Huawei Mate 40 RS uses self-developed storage chip

A few days ago, Aio Technology released the teardown video of Mate 40 Pro. Yesterday, they released the teardown video of Mate 40 RS and compared the two phones' internals. From this, we can see the improvement of mate 40 RS in hardware.

First of all, heat the back cover for about 3 minutes, and then use the suction cup and pick to remove the back cover. It is worth mentioning that the weight of the back cover has reached 40 grams.

The Mate 40 RS still uses a three-stage design. Its middle and lower parts are almost the same as Mate 40 Pro, only the upper part is different.

Then remove the screws securing the motherboard cover and tear off the tape at the bottom. This motherboard cover integrates the NFC induction coil, wireless charging module, an infrared temperature sensor.

Then remove all fixing screws and disconnect all cables connected to the motherboard, remove the camera module and motherboard.

In order to install the camera, the middle of the motherboard of the Mate 40 RS is completely hollowed out, and then remove the metal shield covering the chip on the motherboard.

We found that the ROM chip has a HiSilicon logo, which should be a chip developed by Huawei. Previously tested by digital bloggers, Huawei Mate 40 Pro read and write performance can reach about twice the speed of UFS 3.1.
SFS 1.0 ROM

It is reported that Huawei Mate 40 Pro and the above models use HiSilicon's self-developed SFS 1.0 ROM chip. Compared with UFS 3.1, the random read and write speed is almost doubled. At present, the average sequential read speed of UFS 3.1 is about 1800MB/s, the sequential write speed is about 700MB/s, and the random write is about 200-300M/s.

In the latest Huawei Mate 40 Pro benchmark, we found that the phone's sequential read speed at 1966M/s, sequential write speed at 1280M/s, random read at 383M/s, the random write at 548M/s. Its random write speed is twice that of UFS 3.1.

SFS is a new type of flash memory developed by Huawei. However, since Huawei officials rarely mention this new flash memory technology and have never promoted it at the mobile phone conference, we currently know very little about this new technology.
