(CCM) - Do you know Nano Memory cards? Probably not, because it is a new format of memory card designed by Huawei. With what he calls the NM Card, for Nano Memory Card therefore, the Chinese manufacturer intends to supplant the MicroSD cards, a format already aged fifteen years and he considers outdated. To the point of choosing not to use it in its brand new Mate 20 and Mate 20 Pro that have just been presented.

If the name Nano Memory Card reminds you of the nano SIM, it's not for nothing! Because the format of the Nano Memory cards is exactly the same as that of the smart cards of our phones. And for good reason: Nano Memory cards can be installed in the same space as nano SIM cards. This will be the case on the Mate 20 and Mate 20 Pro, which will be Dual-SIM devices.

In terms of space proposed, a NM card will offer at least 128 GB of storage for a transfer rate of 90 MB per second. While this format may be more practical on paper, it is not certain that it is supplanting microSD cards anytime soon and the main reason is that the Nano Memory format is a proprietary Huawei format.

As a result, the supply is relatively limited and rather expensive as other manufacturers do not seize it. Do you remember Memory Stick, the proprietary storage format created by Sony? It's not for nothing that he has now sunk into oblivion. Huawei would do well to avoid the same mistake for the Nano Memory to be successful.
