What Is The Main Difference Between MicroSDHC And MicroSDXC Cards?
The main difference between microSDHC and microSDXC cards lies in their storage capacity and compatibility. microSDHC (High Capacity) cards are designed to store up to 32GB of data, while microSDXC (eXtended Capacity) cards can store up to 2TB of data. This means that microSDXC cards offer much larger storage capacities, making them ideal for devices that require more storage space, such as 4K video cameras and high-end smartphones.
Additionally, microSDHC cards are compatible with devices that support SDHC, while microSDXC cards are compatible with devices that support SDXC. This means that if your device only supports SDHC, you won’t be able to use a microSDXC card, even if it’s compatible with the physical size of the card slot.
Can I Use A MicroSDHC Card In A Device That Supports MicroSDXC?
Yes, you can use a microSDHC card in a device that supports microSDXC. Since microSDXC devices are backward compatible with SDHC cards, you can insert a microSDHC card into a microSDXC device and it will work just fine. However, keep in mind that the card will only operate at the maximum capacity of the microSDHC card, which is 32GB.
It’s worth noting that using a microSDHC card in a microSDXC device may not be the most efficient way to use your storage space. If your device supports microSDXC, it’s recommended to use a microSDXC card to take advantage of the larger storage capacities available.
Can I Use A MicroSDXC Card In A Device That Only Supports MicroSDHC?
No, you cannot use a microSDXC card in a device that only supports microSDHC. microSDXC cards require specific hardware and software capabilities to function properly, which may not be present in devices that only support microSDHC. If you try to use a microSDXC card in a device that only supports microSDHC, the card may not be recognized or may not function correctly.
In some cases, the device may even refuse to recognize the microSDXC card or may cause errors when trying to read or write data to the card. To avoid any potential issues, it’s recommended to check the device’s specifications before purchasing a microSD card to ensure compatibility.
