A Brief Overview of SanDisk Ultra and SanDisk Extreme

SanDisk Ultra Overview

The SanDisk Ultra series of memory cards is designed specifically with the needs of amateur photographers and beginners in mind. This makes them particularly suitable for use in devices such as entry-level DSLRs , compact digital cameras, smartphones, and tablets, where high-speed processing and data storage might not be a primary requirement. Despite the lower read/write speeds, which may not meet the demands of professional-grade cameras, the Ultra range impresses with its wide compatibility across various devices and affordable pricing. This accessibility makes it a preferred choice for individuals just beginning to explore the world of digital photography. Furthermore, the product line-up of the SanDisk Ultra is vast, including not only the standard SD/SDHC/SDXC cards but also microSD/microSDHC/microSDXC cards and even CompactFlash cards. This broad range caters to different storage needs and preferences, offering users ample options to choose from.

SanDisk Extreme Overview

The SanDisk Extreme series, on the other hand, offers more power and faster read/write speeds than the Ultra line. These enhanced capabilities enable the Extreme series to support higher-quality 4K video recording and high burst rate for action shooting, which are often sought after by more advanced or professional photographers. Positioned as an intermediate option between the Ultra series and the top-of-the-line Extreme PRO, the Extreme series provides a balanced solution for users requiring higher performance but at a moderate cost. However, potential buyers should take note not to confuse the SanDisk Extreme with the more powerful SanDisk Extreme PRO, which boasts even greater performance at a higher price point. The SanDisk Extreme range also offers a variety of formats, including microSD and SD cards, and even extends to CompactFlash cards.


  • Speed Class (C10) : Both the SanDisk Ultra and Extreme memory cards belong to the C10 speed class. This classification ensures a minimum write speed of 10MB/s, making these cards suitable for various applications. Whether capturing high-resolution images or recording Full HD videos, the C10 speed class can handle these tasks efficiently. The C10 classification also means that these cards can support sequential write speeds necessary for smooth media playback and file transfer, providing a consistent experience for users.

  • UHS Class – Bus Interface (UHS-I) : The UHS-I bus interface is a shared feature between the Ultra and Extreme series. This Unified Host Speed class denotes a theoretical maximum transfer speed of 104MB/s. While the real-world speeds may vary depending on the devices used, the UHS-I classification ensures a robust performance for both reading and writing operations. This can lead to quicker file transfers, more responsive photo previews, and smoother video playback, significantly enhancing user experience.

  • Storage Format (SD, SDHC, SDXC and CompactFlash cards) : Depending on the storage capacity, both Ultra and Extreme cards can be formatted as SD (up to 2GB), SDHC (4GB to 32GB), or SDXC (64GB and higher). This categorization plays a significant role in determining how the cards are utilized. The SDHC cards, formatted in FAT32, have a limit where individual files can’t exceed 4GB, making them suitable for general usage, such as storing photos, music, and standard videos. SDXC cards, on the other hand, are formatted in exFAT, allowing for individual files larger than 4GB. This makes them a preferred choice for professionals and enthusiasts who may work with extensive high-definition video files or other substantial data. The option to choose between different formats provides flexibility and ensures that users have the right tool for their specific needs, whether it’s casual use or more demanding applications.

  • Durability : Durability is a standout feature for both card series. Designed to withstand water, temperature extremes, shocks, drops, and airport X-rays, these cards are built for the rigors of daily life. Whether you’re a traveler facing various environmental conditions or simply want a card that can endure everyday wear and tear, both Ultra and Extreme offer robust protection.

  • Compatibility : Both Ultra and Extreme cards maintain compatibility across various host devices. Their adherence to industry standards means that they can be used interchangeably in most devices that accept SD or microSD cards. This provides flexibility for users who may own multiple devices and require a versatile memory card solution.

  • Warranty : Both card series often come with a manufacturer’s warranty, providing added peace of mind. This warranty covers manufacturing defects and other potential issues, underscoring SanDisk’s confidence in the quality and longevity of their products.


  • Read/Write Speeds : The read and write speeds set the two card series apart significantly. The Ultra cards offer write speeds of up to 80MB/s, while Extreme cards can reach up to 90MB/s. The read speed for Extreme is even more impressive at 160MB/s. These variations in speed may seem minor but can substantially affect the user experience. For example, higher write speeds allow for faster saving of high-resolution photos, enabling more seamless burst photography. The increased read speed enhances data transfer between devices, cutting down waiting times for professionals who need to access or back up their work swiftly. In high-demand scenarios like 4K video recording, these speeds could be the difference between smooth performance and dropped frames.

  • UHS Speed Classes : The Ultra series falls under UHS Speed Class U1, with a minimum write speed of 10MB/s. In contrast, the Extreme series is classified as U3, ensuring at least 30MB/s. This distinction is vital for applications requiring quick data writing, like continuous shooting in photography or recording high-resolution videos. For media professionals or enthusiasts seeking optimal performance in capturing fast-moving subjects or detailed videos, the Extreme’s U3 classification may provide a clear advantage.

  • Video Speed Class : The Extreme series carries the V30 classification, guaranteeing a sequential write speed of 30MB/s. This is sufficient for smooth 4K video recording. Although Ultra cards lack a specific video speed class, they can handle Full HD 1080p video recording due to the C10 classification. This difference could be significant for those involved in professional video production, where the higher video speed class of the Extreme cards would ensure uncompromised 4K recording quality.

  • Transfer Speeds :
    Micro SD Card : The Extreme series boasts a transfer rate of 190MB/s as opposed to Ultra’s 120MB/s. This difference expedites file transfers, which can be crucial for professionals dealing with large media files. The increased speed enhances efficiency in managing data, saving valuable time during post-production workflows.

    SD Card : The difference in transfer speeds between Extreme (150-180MB/s) and Ultra (120-150MB/s) becomes even more pronounced with SD cards. This increased transfer rate can be a crucial factor for photographers and videographers who work with large file sizes, enabling quicker backups, transfers, and editing.

  • Storage Capacity : The Ultra series offers a wide array of capacities, from 16GB all the way up to 1TB for microSD, and 16GB to 512GB for SD cards. This range caters to various users and applications, from casual smartphone usage to professional photography. Extreme cards, although more limited in range from 64GB to 256GB for microSD and 32GB to 256GB for SD, focus on capacities that are often preferred by professional users. The addition of CompactFlash cards within the Extreme series further expands options for those requiring this specific format.

  • Shot Speeds : A unique feature to the Extreme series is the Shot speed, enabling up to 70MB/s. This capability is designed for capturing high-speed action shots without compromise. Whether it’s sports, wildlife, or any other fast-moving subject, the Shot speeds ensure that each frame is captured with precision. For photographers focusing on action or those needing rapid shot-to-shot performance, the Extreme series offers a significant edge.

  • Cost : Price considerations highlight another difference between these series. Generally, the Ultra series is positioned as a more budget-friendly option, catering to casual users or those not requiring top-tier performance. The more affordable pricing opens accessibility to a broader audience, including students, families, or hobbyists. The Extreme series, with its array of enhanced features and capabilities, tends to be priced higher. This pricing reflects its target audience: professionals, enthusiasts, and others who need superior performance and are willing to invest in achieving it.
