The memory card is one of the most prominent storage tools that smartphones rely on in the first place, but over the years the shape of these cards has changed, as they became smaller as the years progressed. The beginning was with SD cards, or what is known as “Memory Stick Duo”, which is one of the types of memories. Interchangeable flashlight.

And it was developed by Sony, and based on the principle of the Memory Stick, and it measured 20 mm x 31 mm. The largest capacity it has reached is 8 GB, and these memory cards have been developing into microSD, and below we show a comparison that shows the difference between the two types as follows:

The difference between the microSD and SD storage cards

Due to the demand for smaller portable electronic devices, by the early 2000s, the traditional SD card was too large for many types of devices, such as smartphones, to appear in 2005 for the first time a microSD card was about one-sixth the size of an SD card and half its thickness, with dimensions The SD card is approximately 32 x 24 x 2.1mm, while the microSD card has dimensions around 15 x 11 x 1mm.

Nature of use:

Despite their small size, microSD cards have the same basic architecture, including the same electrical pinout connections, thus, instead of requiring a new microSD card slot on computers, microSD cards can slide into adapters and use the existing SD card slots.

The difference between the two cards:

Regardless of size, the main difference between SD cards and their microSD siblings is capacity. While the latest “ultra-high capacity” SDUC cards can support up to 128 terabytes, the microSD format is limited to a maximum of 1 TB.

Additionally, while most SD cards have write protection tabs that allow you to lock them from writing or erasing, the microSD card does not have space for a physical write protection tab and thus cannot be locked.
