About SanDisk

SanDisk Extreme III CompactFlash is designed for serious professional photographers who demand one of the fastest, most rugged and most durable memory cards on the market. Professional photographers who work under less than ideal conditions expect more from a flash memory card. More speed. More performance. More reliability. SanDisk's Extreme III card delivers everything you want plus a whole lot more.

That's because only SanDisk Extreme III memory cards feature innovative ESP technology for the fastest speeds and highest performance. ESP stands for "Enhanced Super-Parallel Processing". Simply put, it means you are getting the fastest read / write speeds available, speed you'll definitely appreciate whenever you find yourself shooting and storing pictures in harsh environments, extreme temperatures or at high altitudes.

Every SanDisk Extreme III CompactFlash card comes with RescuePRO so you can recover images, documents, mail, video, music - just about any digital file, with ease. Built with leading-edge media recovery algorithms, RescuePro lets you preview recoverable data before you try to retrieve it. With RescuePRO's unique recovery algorithm for MPEG audio and MPEG video recovery (MPEG-1/2/3) what you see and what you hear, is what you can recover.

Speed makes all the difference!

Having a high speed memory card makes such a difference. I am by all means not a professional - but, if you have kids, I can't tell you how much of a difference a higher speed memory card has made in capturing images before the kids have moved on, and the time loading them to my computer has been greatly reduced. Yea!!!

Rebate Scam!

Professional photographer making digital images/video. Fast write speeds. Have to deal with Sandisk to get it.

Great Card for all photography


from California  -  Semi Pro

Excellent card. I have used for portrait sessions, landscape, and sports. It writes fast enough for all of them even at 6fps.


Great Card


from Tierra Verde, Florida  -  Professional

I get great and clear images using this card.


Great card for most CF compatible DSLRs


from Cedar Falls, IA  -  Hobbyist/Enthusiast

Fast, good capacity, good balance


Great ! Excellent Product

Pro Series Photography and Reference Photos


Excellent card, very reliable and fast.


from Minneapolis, MN  -  Semi Pro

The card has been great in my 50D since I purchased it about 2 months ago. Rock solid and fast. For the price, it is hard to beat.


Great memory!


from Kansas City, MO  -  Hobbyist/Enthusiast

I use the compact flash in my Canon 1D Mark III. The write time is fast and the reliability is great.


Another Great SanDisk product


from Boyertown, PA  -  Hobbyist/Enthusiast

Great product.


I have had several of these cards fail.


from Trussville, AL  -  Semi Pro

Over a three year period I have had four Sandisk CF cards come apart. One became unusable and another occasionally corrupts files. I have since switched to Lexar Pro but I have not used them long enough to compare.




from Boston,Ma  -  Hobbyist/Enthusiast

very useful and affordable cf reads relatively fast and very reliable.


Reliable But Beware


from Ripton, Vermont  -  Professional

Not recommended for high continuous RAW shooting such as weddings or sports. Though it eventually keeps up, it does lag behind and sometimes acts like the camera can't shoot. Also not helpful when you do want to do a quick check. I love the cards, just wish I had bought a higher read/write speed. Otherwise reliable.
