In contrast, the SanDisk Extreme offers a higher write speed of up to 90MB/s. This increased speed contributes to shorter buffering times, making it a more efficient choice for 4K video recording and high-speed photography.

Furthermore, the Extreme series benefits from Ultra DMA technology, doubling the read and write speeds compared to the SanDisk Ultra Plus.

Read Speeds and Buffering

Read speed, which determines how quickly data can be accessed from the card, is another critical factor. The SanDisk Ultra offers a read speed of up to 120MB/s, while the Extreme variant goes further, offering a read speed of up to 160MB/s for certain models.

This increased read speed is particularly beneficial when transferring large files or high-resolution images to a computer, thereby enhancing the overall workflow efficiency.

Speed Class and UHS Rating

Both card ranges come with a Speed Class of C10, indicating a minimum write speed of 10MB/s, which is sufficient for Full HD video recording. However, in terms of the UHS (Ultra High Speed) class, SanDisk Extreme cards are rated as U3, meaning they have a minimum write speed of 30MB/s.

This is higher than the U1 rating of SanDisk Ultra, which stands at a minimum of 10MB/s. These ratings are crucial for users who need consistent performance for high-resolution video recording and rapid burst photography.

Storage Capacities and Formats

The capacity and format of a memory card are crucial in determining its suitability for various devices and applications. These factors dictate not only how much data the card can hold but also its compatibility with different types of cameras and devices. 

SanDisk’s Ultra and Extreme lines offer a range of capacities and formats, catering to a diverse spectrum of storage needs and device requirements.

Range of Storage Capacities

SanDisk Ultra memory cards come in an extensive range of capacities, from as low as 16GB to as high as 1TB. This broad spectrum makes them a versatile choice for users with varying storage needs, from casual photography to extensive video recording.

On the other hand, SanDisk Extreme cards are available in capacities up to 256GB, which, while lower than the maximum offered by Ultra, is typically sufficient for most high-performance use cases, such as 4K video recording and high-speed burst photography.

Memory Card Formats

Both SanDisk Ultra and Extreme memory cards are available in various formats, including SD (Secure Digital), SDHC (Secure Digital High Capacity), and SDXC (Secure Digital Extended Capacity). The format is an important consideration as it affects the card’s compatibility with different devices.

SD cards are universally compatible with all devices supporting SD, SDHC, and SDXC. SDHC cards, formatted in FAT32, work with most modern devices but may not be compatible with older devices that only support SD.

SDXC cards, using the exFAT format, are ideal for newer devices, offering higher capacities and better performance but require SDXC-compatible equipment.

File System and Compatibility

The file system used in these cards also plays a crucial role in their functionality. SD cards use the FAT16 file system, while SDHC cards use FAT32, and SDXC cards employ exFAT.

These file systems have different file size limits and performance characteristics. For instance, FAT32 restricts individual file sizes to 4GB, which can be a limitation for extended high-resolution video recordings.

The exFAT system of SDXC cards, used in higher capacity SanDisk Extreme models, allows for larger file sizes and is generally faster, making it more suitable for demanding photography and videography tasks.
