Huawei introduced a proprietary memory card format called NM card in October 2018 and has been using it on most devices for five years. The standard has not been adopted outside of the Chinese manufacturer’s devices, and memory manufacturers have understandably been in no hurry to adopt it.
Yet now that Huawei’s sales are seemingly picking up, Lexar is getting on board. Until now the largest NM card available was 256GB, but the company has now launched a new NM card with 512GB capacity.
The NM card is a third smaller than the micro SD card and fits into the nano-SIM slot. The reason why other companies have not adopted this standard is the more complex design and technical difficulties, which would increase costs.
There is also the marketing part where smartphone companies prefer users to stay in their ecosystem and use internal cloud storage like Google Drive, Apple iCloud, Samsung Cloud, Mi Cloud, etc.
The new Lexar product supports the eMMC 5.1 protocol and offers a read speed of 90 MB/s and a write speed of up to 85 MB/s, which are not as fast as current onboard memory, but more than enough to run in 4K. videos on a Huawei smartphone.
The 512GB NM card has yet to appear for sale online. We expect a price well above $100/€100/£100, as the current 256GB NM card is between $50 and $80 on Vmall, Amazon, and some offline stores.
