MicroSD: Explained: What is nano memory and how is it different from microSD cards?

nano memory whatever it is called nm card either Encard is a memory solution designed and developed by Huawei. This memory solution was introduced in 2018 as a new, smaller memory card for phones with minimal space. Nano memory cards are as small as a nano-SIM and have dual . can be used with Sim tray in an accompaniment Huawei Device. Since launch this format has never received support from major memory card developers and other OEMs, therefore, this technology is limited to Huawei devices only. As smartphones start coming with more built-in storage, the need for expandable storage along with the need for nano memory cards is reduced, even eliminating the obscurity. Here we will discuss how the Nano memory card differs from the more common one. MicroSD card.
How is nano memory card different from microSD card?
The Nano memory card is an expandable storage format developed by Huawei that is similar to a traditional microSD card. These cards are as small as nano-SIM cards which are about 45% smaller than the more popular microSD cards. However, these NM cards are only supported by Huawei devices that fit in the dual-nano SIM card tray in compatible devices and do not require a separate card slot to function.
Features and Availability of NM Card
Huawei currently offers these nCards in three different storage variants – 64GB, 128GB and 256GB sizes, while the 64GB variant is hardly available. These cards are based on the eMMC 4.5 flash storage protocol and offer read speeds of up to 90MB/s.
Advantages of Nano Memory
Other than size and read speed, NM cards aren’t much different from traditional microSD cards. The user experience will be almost the same in both the cases, however, device makers may see a big advantage in using nano memory.
Manufacturers can use this to free up space inside their smartphones to fit in other components. For example, these NM cards fit in Huawei’s dual-nano SIM tray which can completely eliminate the need for an additional memory slot.
This may seem like a very small advantage, but the physical space in a smartphone is very limited and microSD card support can become a deciding factor regarding the design and placement of the device’s circuit board. Using a SIM tray for expandable memory can give manufacturers more options in how they design their devices and the components they use.
However, microSD doesn’t interfere with other physical aspects of the phone like how you place it or its IP rating. It’s important to note that manufacturers are usually reluctant to adopt a patented technology from one of their competitors if it doesn’t bring a big incentive.
Disadvantages of Nano Memory
NM cards are quite expensive when their performance is compared with similar microSD cards. MicroSD cards with the same memory size and higher read speeds will cost Huawei less than half the price of its NM cards.
These NM cards offer only three size options whereas microSD cards are available in multiple size variants. MicroSD cards can offer up to 1TB of storage and come in several options with 90MB/s read speeds and more. However, the biggest disadvantage of NM cards is limited support.
Android Smartphones that support microSD cards are readily available and are very common. NM cards will only work with Huawei phones. Also, users will have to choose between using a second SIM card or expandable storage as these NM cards occupy the SIM tray slot. This can be a problem for users who need to use both their SIM connections.
