Note: The MMC is a memory card standard for storage. Compared with the SD card, it has more storage capacity options and more pins, but with a lower speed in transfer rate. Moreover, it is not as up-to-date as SD cards.

This card usually is used in devices like cell phones, PDAs and smaller and lighter devices. The microSD card can be read by regular SD card slots via an adaptor. It uses FAT12, FAT16, or FAT16B file system.

The capacity is the primary difference between microSD and microSDHC. The maximum storage size of a microSD card is 2GB, while that of a microSDHC card is 32GB. The common-to-see capacities of a microSDHC are 16GB and 32GB.

Tip: The added “HC” in microSDHC refers to high capacity.


The maximum read and write speed of the microSD card is 25MB/s. Considering its small size, this speed is pretty fast. Compared with the microSD card, the microSDHC card has a higher transfer rate ranging from 50MB/s to 150MB/s.

The speed of these memory cards depends on the speed classes they apply (2, 4, 6, 8, and 10). The respective minimum serial data writing speed of them are 2MB/s, 4MB/s, 6MB/s, 8MB/s, and 10MB/s.

The microSDHC and microSDXC cards’ speed are marked by UHS 3 or UHS 1. The minimum speed of UHS 1 is 10MB/s, while that of UHS 3 is 30MB/s.

You can also test the speed of the SD memory card manually. For that, the Disk Benchmark feature of MiniTool Partition Wizard helps. Download this program by clicking the button below and then follow the on-screen instruction to finish the installation.

The microSD card is usually used for mobile phones for storing photos, videos, and applications.

The microSDHC can be used on devices including telephones, tablets, action cameras, 360-degree cameras, and drones. The micro SDHC host devices are asked to accept older SD cards, which indicates that the older SD cards with new technologies can comply with an SDHC device.


When buying a memory card, you should also take compatibility into consideration. If the card is not compatible with your device, it doesn’t make sense. MicroSD cards can work with new host devices. It means that they are compatible with SD, SDHC, and SDXC host devices.

As for micro SDHC cards, they are incompatible with SD host products. But they are compatible with SDXV and SDHC devices.
