The SanDisk Memory Card Lineup


SanDisk offers an array of memory cards comprising CompactFlash, SDHC/SDXC, and microSDHC/SDXC types in a wide range of capacities and data-transfer speeds. Faster speeds enable improved performance during HD video and RAW image capture, especially in continuous and burst shooting modes, and when using advanced modes like slow-motion recording. Fast cards also improve workflow efficiency by speeding up card-to-computer file transfers. Many of the cards feature waterproofing and other durability characteristics, and all are built for use in extreme temperatures ranging from -13 to 185°F.

Top Camera Performance

For the fastest transfer speeds and overall performance, the Extreme Pro cards are available in the SDHC/SDXC design, in 8-, 16-, 32-, and 64GB capacities. SanDisk reports that these are the world’s fastest SD cards and are Class 10 UHS-I rated and they provide read and write speeds of 95MB/s and 90MB/s, respectively, with minimum sustained speeds of 10MB/s. The SD card design incorporates a write-lock switch to prevent accidental loss of data.

The CompactFlash Extreme Pro cards, available in 16-, 32-, 64-, and 128GB capacities, feature a 600x rating with read speeds up to 90MB/s. The 128GB card performs even faster, with a 667x rating and a 100MB/s write speed. These cards support the UDMA mode 7, which designates a maximum theoretical transfer rate of 167MB/s to greatly benefit continuous and high-speed recording applications. The Extreme and Extreme Pro memory cards feature SanDisk's Enhanced Super-Parallel Processing and Power Core Controller to distribute image data across the card more rapidly and efficiently, for faster performance. The controller also extends the life of the card via wear leveling. ECC (Error Correction Code) enhances reliability by automatically detecting and fixing transfer errors. The cards are tested for stress, shock, and vibration resistance, and are treated with an RTV silicone coating for added protection against moisture and humidity.

Next, we have the CompactFlash Extreme cards, available in 4-,  8-, 16-, 32-, and 64GB capacities and in 8- and 16GB two-packs. The cards feature speed ratings of 400x with maximum read and write speeds of 60MB/s, with the exception of the 4GB card, which has a rating of 267x and a maximum speed of 40MB/s. UDMA (Ultra Direct Memory Access) technology allows for faster, smoother photo and video capture and transfer from card to computer than would otherwise be possible. UDMA memory cards will achieve their fastest transfer rates with UDMA-compatible host devices. These cards are UDMA 5 compliant.

The SDHC/SDXC Extreme cards feature similar performance attributes and are available in 8-, 16-, 32-, 64-, and 128GB capacities, as well as two-packs of 16- and 32GB cards. The 8GB card has a maximum read/write speed of 30MB/s while the higher capacity cards offer 45MB/s transfer speeds. All cards are designated as Class 10 UHS-I and support a minimum transfer rate of 10MB/s to better suit HD video recording.

When Accidents Happen

Additionally, the Extreme and ExtremePro series of cards also include a one-year subscription to the RescuePro data recovery downloadable software, which helps to recover accidently deleted and corrupt images.

Smaller in Size but Still Large in Capacity and Performance

Designed for compact cameras, action cameras, mobile phones and tablets, the microSDHC/SDXC Ultra series of cards, available in 16-, 32-, and 64GB capacities, provide Class 10 UHS-I support and offer maximum read and write speeds up to 30MB/s. These small-form-factor cards include an SD card adapter that expands their dimensions to that of an SD card. This provides greater versatility for use and also enhances their compatibility with a wider array of memory card readers, computers, and other devices.  

The Ultra series of cards are also available in the native SD form, in SDHC/SDXC capacities of 8-, 16-, 32-, and 64GB. Like the microSDHC/SDXC cards, these, too, are Class 10 UHS-I cards that have a maximum read speed of 30MB/s with a minimum sustained write speed of 10MB/s. Both types of cards have a water-, shock-, and X-ray-proof design to enhance their durability.

Trust SanDisk

With more than 25 years of building flash memory cards and being one of the top ten technology patent companies in the world, SanDisk is building trust, individually, with each customer. All SanDisk memory cards are designed to ensure the greatest reliability and durability for flash storage to provide a high level of assurance in the protection and consistency of recorded photos, movies, and other media and data. Their array of formats to fit all cameras and breadth of capacities and transfer speeds are posed to suit any shooting application ranging from intensive high-definition video recording to casual snapshots.

i bought SDHC CARD , it is not playing on my computer no picture showing i well need help thanks.

I am very sorry you are having this issue with your memory card.  In order for us to best troubleshoot this issue for you, we need a bit more information.  If you could send an email to our email support division at, and please make sure to include the model of your camera, the type of computer you are using and the Operating System on it, and also please indicate if you connect the memory card into a card reader on the computer, or if you are connecting the cameras directly to the computer via USB.  Once we have that much information we can work towards helping you resolve this.

I purchased the extreme sandisk 32 card less than a year ago and it is missing data from a vacation. when i try to download onto the computer or insert in the camera, it says the card is empty . my camera is the canon 60D my computer is a large imac with 10.9.2

Like any type of storage, memory cards can become *******. I recommend trying a data recovery program like ProSoft Data Rescue 3. ( In the future to prevent data loss I would recommend formatting the card in your camera before use. (And of course once you have imported previous images)

When i try and access my Sandisk "Wake up your phone" adapter cárd I get a message of memory card error card locked. I know i have pictures on there, how do I get past this?

I apologize for your troubles. In order for us to best assist you, please email us at with more specific information, including the memory card and phone you are using, service provider, and any other pertinent details that we can use to figure out this issue.
