In the realm of digital storage, SD cards reign supreme as compact and versatile options for expanding the capacity of various devices. Among the different types available, SDHC (Secure Digital High Capacity) and SDXC (Secure Digital Extended Capacity) cards stand out as popular choices. Understanding the distinction between SD card HC1 vs XC1 is crucial for making informed decisions based on your specific storage needs.
Speed and Performance
One of the primary differences between SDHC and SDXC cards lies in their speed and performance capabilities. SDHC cards adhere to the UHS-I (Ultra High Speed Phase I) bus interface, supporting theoretical maximum read and write speeds of up to 104 MB/s. On the other hand, SDXC cards utilize the faster UHS-II and UHS-III bus interfaces, enabling speeds of up to 312 MB/s and 624 MB/s, respectively.
Capacity
As their names suggest, the most significant difference between SDHC and SDXC cards is their storage capacity. SDHC cards have a maximum capacity of 32 GB, while SDXC cards can accommodate up to 2 TB. This substantial difference makes SDXC cards ideal for storing large files, such as high-resolution videos, RAW images, and software applications.
Compatibility
SDHC and SDXC cards are backward compatible with older devices that support SD cards. However, it’s important to note that devices designed for SDHC cards may not be able to fully utilize the faster speeds and higher capacities of SDXC cards. Conversely, devices that support SDXC cards will also work with SDHC cards.
Use Cases
The choice between SD card HC1 and XC1 depends on the intended use case. For general storage purposes, such as storing documents, music, and photos on smartphones or digital cameras, SDHC cards with capacities up to 32 GB are sufficient.
For more demanding applications, such as storing and editing high-resolution videos or running software on portable devices, SDXC cards with higher capacities and faster speeds are recommended.
File System
SDHC cards use the FAT32 file system, which has a maximum file size limit of 4 GB. In contrast, SDXC cards use the exFAT file system, which supports file sizes up to 16 TB. This difference is crucial for storing large files that exceed the 4 GB limit.
Price
Generally, SDHC cards are more affordable than SDXC cards due to their lower capacities and speeds. However, the price difference between the two types has narrowed over time.
Key Points: Making the Right Choice
Choosing the right SD card HC1 vs XC1 depends on your specific needs and budget. If you require a compact and affordable option for general storage, SDHC cards are a suitable choice. For high-capacity storage and faster performance, SDXC cards are the preferred option. By understanding the key differences between these two types of cards, you can make an informed decision that meets your requirements.
