Memory cards have become an essential part of our digital lives, providing us with the ability to store and transfer large amounts of data on devices like smartphones, tablets, and cameras. When it comes to memory cards, two of the most common types are Micro Secure Digital High Capacity (Micro SDHC) and Micro Secure Digital Extended Capacity (Micro SDXC). These two card formats offer different levels of storage capacity and speed, making it important to understand their differences before making a purchase.
What is Micro SDHC?
Micro SDHC is a type of memory card that was introduced in 2006. It has a storage capacity ranging from 4GB to 32GB and supports the FAT32 file system. Micro SDHC cards are ideal for use in devices that require moderate storage space, such as digital cameras and MP3 players.
What is Micro SDXC?
Micro SDXC is a more recent type of memory card that was introduced in 2009. It has a storage capacity ranging from 64GB to 2TB and supports the exFAT file system. Micro SDXC cards are designed for use in devices that require high storage capacity, such as smartphones, tablets, and action cameras.
Storage Capacity: Micro SDHC vs Micro SDXC
The primary difference between Micro SDHC and Micro SDXC is their storage capacity. Micro SDHC cards have a maximum capacity of 32GB, while Micro SDXC cards can have a capacity of up to 2TB. This makes Micro SDXC cards a better choice for storing large amounts of data, such as high-resolution photos, videos, and music files.
Speed: Micro SDHC vs Micro SDXC
Another important difference between Micro SDHC and Micro SDXC is their speed. Micro SDHC cards typically have a speed rating of Class 4 or Class 6, while Micro SDXC cards have a speed rating of Class 10 or UHS-I. The speed rating indicates the minimum sustained write speed of the card, which is important for tasks such as recording high-quality videos or capturing burst shots.
Compatibility: Micro SDHC vs Micro SDXC
Micro SDHC cards are compatible with all devices that support SDHC cards, including older devices. However, Micro SDXC cards are only compatible with devices that specifically support SDXC cards. If you have a device that does not support SDXC cards, you will need to use a Micro SDHC card instead.
Price: Micro SDHC vs Micro SDXC
Micro SDHC cards are generally less expensive than Micro SDXC cards, especially for cards with smaller storage capacities. However, the price per gigabyte of storage is typically lower for Micro SDXC cards, making them a more economical choice for larger storage capacities.
When to Use Micro SDHC
Micro SDHC cards are best suited for devices that require moderate storage capacity and do not need high speeds. This includes devices such as digital cameras, MP3 players, and e-readers.
When to Use Micro SDXC
Micro SDXC cards are ideal for devices that require high storage capacity and fast speeds. This includes devices such as smartphones, tablets, action cameras, and drones.
Tips for Choosing the Right Micro SD Card
- Consider your storage needs: Determine how much storage space you need before purchasing a card.
- Check device compatibility: Make sure that your device supports the type of card you want to purchase.
- Choose the right speed rating: Select a card with a speed rating that meets the requirements of your device.
- Consider the brand: Choose a reputable brand that offers reliable and high-quality memory cards.
