Mini SD Card VS Micro SD Card VS SD Card, What Are the Differences

Is a Mini SD card the same as a Micro SD card? No, Mini SD card and Micro SD card are two types of cards derived from SD memory cards. We will talk about the differences about regular SD card, Mini  SD card, and Micro  SD card from the following points.

sd card, mini sd card, micro sd card

  • Physical Size: The size of an ordinary SD card is about 1.25 × 0.95 inches, the size of a Mini SD card is 0.87 × 0.79 inches, and the size of a Micro SD card is 0.43 × 0.59 inches. Both Mini SD card and Micro SD card can be used as SD cards through the card reader or card adapter. But the big SD card can't fit into a small card slot.
  • Storage Capacity: Different SD cards follow different standards, which will affect their maximum storage capacity. The original SD card standard allows a maximum capacity of 2GB, while a card using the SD high-capacity standard can have a maximum capacity of 32GB. The SD extended capacity standard allows capacities between 32GB and 2TB. There are three sizes of SD card and SDHC card. However, SDXC cards can only be used as full-size or Micro SD cards.
  • File System: According to different standards, different capacity, SD card can choose different file systems, some support FAT16, some support FAT32, some also support exFAT.  If your SD card’s capacity is under 32GB, you can choose FAT16 or FAT32. If the capacity is larger than 32GB, you can choose exFAT.
  • Cost: Generally speaking, smaller SD cards are more expensive than larger ones. This is largely due to higher manufacturing costs, as smaller components require higher manufacturing precision. However, the card size usually has a greater impact on cost than the size itself. For example, a full-size Class 10 SDXC card may be more expensive than a Class 2 Micro SDHC card, even though the Class 2 card is physically smaller.

Mini SD Card Overview

There are three kinds of SD cards, SD card, Mini SD card, and Micro SD card, also called TF card. They are just different in size and compatible with each other.

The Mini SD card is small in size, stable in performance, and relatively common. As a slender multimedia card, the Mini SD card is widely used in the mobile phone market, such as Motorola MPX100, Panasonic X700, BQ S700, and other brands of mobile phone products that support it. At the same time, it can be used as a standard SD card through an expansion card, which is very convenient.
