Reoqoo High Speed MicroSDHC MicroSDXC 1 Class 10 Memory Card Storage Card Micro SD Card

1. Capacity

For a storage media, capacity is a paramount factor. From the introduction to SDHC and SDXC, you may have some idea.

Until now, the capacity of the SDHC card is from 4GB to 32GB. To put it more specific, the SDHC card is in the following capacities 4GB, 8GB, 16GB, 32GB. For the SDXC card, the maximum is up to 2TB.

A conclusion can be made that the SDXC card enables you as a camcorder user to save much longer high-definition videos than the SDHC card can offer.

2. Speed Capacity

When we evaluate the memory card for camera use, we should pay attention to one component of such card that is its speed capacity.

The memory card’s speed is very important when filming on a high-resolution camera, since it ensures that you can capture everything smoothly. In other word, a slower memory card is likely to become overwhelmed and could potentially not record at all.

The SD card has Speed Class to show the minimum writing performance to record standard and HD video. These classes are defined by one of four numbers: 2, 4, 6, and 10. Class 2 offers up to 2MBps, while the other 3 classes offer up to 10MBps.

In fact, some standard definition cameras support the Class 2 card. However, if the camera with high definition, it is suggested to choose a Class 4 or 6 card, for they are faster and can better handle the transfer rate of high definition recording.

The SDHC card’s speed capacity is up to 10MBps, while the SDXC card’s speed capacity is up to 300MBps. Obviously, the latter is far faster than the former, which is also the reason that the SDXC card is usually offered to camcorder users.

3. File System

As mentioned in the content above, the SDXC memory card uses the newer exFAT file system that is more efficient for SDXC’s large capacity. However, the SDHC memory card and SD card use the FAT32 file system.

This difference is the reason that the newer SDXC card is not compatible with host devices that only take the SD card or the SDHC card

What is the difference between micro SDHC and micro SDXC?

Capacity: The capacity of SDHC ranges from 4Gb to 32GB, while the capacity of SDXC is up to 2TB.

Performance: The speed capacity of SDHC can reach 10MBps, while the speed capacity of SDXC can reach 300MBps.

File system: SDHC can be formatted to FAT32, while SDXC should be formatted to exFAT to seek higher efficiency for SDXC’s large capacity.

Price: SDXC is more expensive than SDHC.

Which is better SDHC or SDXC?
