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.

I have a D90, but uncertain which sandisk has the fast read/write speed and fully compatible to this camera. Does anyone have a preferred card for maxium perfermance that best utilizes the performance of the D90?  Thanks for any tips.  - Frank Holt

You might look at one of the SanDisk Extreme SD memory cards.  That would be the line that they recommend for the D90, which would be fully compatible with your camera. 

I had some photos on my scan disk, accidentaly formated my card and want to know how to retreive the pictures I had before the formating occurred, please help.  This just occurred and I need to know if there is a program or something I can do to retreive the pictures they were of my son and grandson's weddings.

I have a Sony HDR PJ260V camcorder which I bought two years ago but have not used much.  I put a SanDisk Ultra 16GB 30MB/s card in it in 2013, and it filled up in August 2014 when I was taking some very important videos.  I put a SanDisk Extreme Plus 16GB 80MB/s card in and finished up our trip videos.  But I am not familiar with uploading videos to my Dell laptop (Win 8.1, 2014), so bought a third card for practice and learning.  It's a SanDisk Ultra Plus 32GB 48MB/s, which I will use to make miscellaneous videos, then load them in the Dell and practice.  I don't know if I have to format the card, and I don't remember what I did with the first two, but they seemed to work okay.  I have not loaded the PlayMemories Home software yet from the camcorder to the Dell, and don't know if there is anything special to look out for.  QUESTIONS:  1.  What are the differences in using the various cards?  2.  What happens if you put the wrong card in for an application, such as extreme HD videos?  3.  Is data from all cards interchangeable once it is loaded into the Dell?  Thanks for you help on this.  Chuck

(PS I am a retired engineer and experienced the beginning of computer use in business, and had a few disasters where important data was accidentally deleted, so I am being super-cautious with these first two cards with very important genealogical videos that cannot be repeated as the events are over.)

I will do my best to answer all of your questions as well as address some points/give some tips whilst keeping this simple.

  1. The differences in the cards you’ve mentioned ultimately are their performance speeds (write/read speeds).  Each has a different top rate that it has been rated to perform at, and each is compatible with your camera.  Your camera is compatible with any SD type memory card as long as the card mentions being a Class 10 card OR having a minimum write speed of 10 megabytes per second (mbps). Your camera will perform the same with any of these 3 cards (performance speed is governed by the camera, and  using a faster card will not cause the camera to go faster, but later if your transferring the data off the  cards either in a slot on  your computer or using an external reader, faster cards will transfer the data off the cards faster (also dependant on the performance speed of the reader in this instance)
  2. Nothing at all.  Memory cards are all designed to work the same way.  Having a card marked “video” is more of a marketing thing.  These days one only needs to regard the performance speeds of the card and make sure they are in line with the camera’s requirements and the card can be used.
  3. Yes it is.

As far as formatting cards go.  Whenever using a card with a camera for the first time, it is best to format the card inside the camera.  Doing this will maximize the space on the card and also instructs the card how to optimally communicate with the camera.  Each time you’ve transferred the data off the camera and it is safely saved on your computer, you should then format the card in the camera (doing so will clear the card again).  It is not advised to format/delete data off the cards via the computer.  Doing so does not fully clear the card and it will not perform optimally later again in the camera.  If you did not format either of your important cards the first time that is ok, once you’ve backed them up format them before use next time.    If you have any further questions, feel free to send us an email to [email protected] and we can reply to you there as well.

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 corrupt. 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)

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