The problem of storage in a laptop or tablet is a big topic and eMMC hard drives are one of the means to help you solve that problem. Let’s find out with Tnhelearning.edu.vn what is an eMMC hard drive? What’s the benefit!
What is eMMC?
eMMC, also known as multi-card storage system, is an abbreviation of the phrase ” embedded MultiMediaCard ” which refers to a package consisting of flash memory and an on-board flash memory controller.
Where is eMMC used?
eMMC is suitable for demanding applications such as portable electronic products (smartphones, tablets, multimedia players, PDAs, navigation systems, digital cameras).
eMMC can be used on mobile devices, memory expansion solutions and replace traditional storage methods (such as HDD).
How does eMMC work?
eMMC serves as primary storage for compact PCs and devices. The chip includes a controller and NAND flash memory, both in “a single integrated circuit”.
This circuit connects to the main board of a device, from which the controller of the eMMC chip can handle the job of putting data into storage . As a result, the device’s CPU can focus on other tasks, avoiding wasting energy and time.
Benefits of eMMC
The architecture of eMMC integrates the flash memory controller into the same package, which simplifies the design of the application interface , so that the processor does not have to manage low-level flash memory.
In addition, eMMC also eliminates the need to develop software interfaces for all types of NAND memory, providing an easy-to-use memory solution for high-speed data transfer on devices such as mobile phones.
Thanks to eMMC, there is also no need for expansion slots by stacking memory functions vertically. This design also helps suppliers to source components from more places, which will help reduce costs and increase revenue.
Features of eMMC
Transfer rate
The eMMC’s SATA standard transfer rate is currently around 550MB/s . However, eMMC memory uses fewer memory gates, so although it can deliver the same speed as other hard drives, the transfer is faster.
Capacity
The general standard of eMMC memories is around 32GB or 64GB , but some eMMCs come in capacities up to 128GB and 256GB of memory.
Price
eMMC is a lot cheaper than SSD and other types of drives, suitable for customers looking for a cheap laptop or mobile device.
How to use eMMC?
The eMMC 4.41 standard delivers security, speed, and reliability like high-level interception or security erasure.
These features need to support the software from the file system, otherwise the application cannot reach the storage via the file system. If you want to switch to eMMC, you need to ensure software support from internal and external sources.
