Differences between SD card and eMMC storage, let Unikeyic take stock!

Many users who frequently need to purchase storage devices in bulk pay attention to eMMC storage and also take note of common SDKs. These two types of storage devices attract a lot of attention due to their similar appearance, but many people are unclear about their differences. In fact, SD cards and eMMC are not the same. Let me share with you the differences between these two small storage devices on unikeyic.

There are differences in application scenarios

Although SD cards and eMMC storage may look similar at first glance, they serve completely different purposes.

eMMC, which uses BGA packaging, is more stable in terms of storage performance and is often embedded in devices for durable and long-lasting use. On the other hand, SD cards are more commonly seen in everyday life as auxiliary storage for electronic devices, mainly for plug-and-play convenience.

Differences in parameters and transfer speeds

In fact, the interface standards of SD cards and eMMC are different. The earlier eMMC was based on the UFS standard, while SD cards have three standards: SD, SD High Capacity, and SD Extended Capacity. In terms of speed, eMMC typically operates at a stable speed of 400MB per second, whereas the speed of SD cards varies depending on the type, ranging from 12.5MB to 624MB per second.

Different advantages in usage scenarios

When it comes to practical applications, both eMMC and SD cards have their own strengths. eMMC supports various file systems like FAT32 and NTFS, enabling intelligent power management that can extend battery life. On the other hand, SD cards excel in compatibility, as they are commonly used as auxiliary storage in many devices. It's worth noting that SD cards come in various classes, making them suitable for a wide range of scenarios.
