SanDisk upgraded their Extreme SD card. The new card is labeled 60MB/s and now has the UHS-I Speed Class 3 (U3) speed designation. The U3 means it can sustain at least 30 MB/s write speed for recording 4K2K video.

Previously the Extreme was labeled 45MB/s (read and write). The new Extreme is advertised as 60MB/s read and 40MB/s write. One might wonder about the new card's downgraded write speed, but it is faster than advertised.

I tested the new SanDisk Extreme 32GB SDHC 60MB/s card using 7 different USB 3.0 card readers. Every one exceeded 75 MB/s read and reached 55MB/s write (range was 54.8-55.3MB/s across all readers with CrystalDiskMark 3.0.3 Sequential 1GB random test data, best of 5 passes). The improved write speed makes the Extreme almost as fast as the Extreme Plus measured at 60MB/s write speed but short of the Plus' 95MB/s highest read speed.

Compare this with the previous generation Extreme 45MB/s, which tested between 44-47MB/s read and 41-43MB/s write.

I recommended the previous version of the SanDisk Extreme quite often in the past. It was a good value considering one could spend twice as much for the Extreme Pro that probably wouldn't be much faster in most digital cameras. But more cameras today support UHS-I and can actually write above 70MB/s. For those cameras faster cards (Extreme Pro) can make a difference. With the Extreme getting a speed boost, it further increases its value and remains a great choice for many cameras.

When I started using a DSLR it took me a little while to learn that there was a difference between a regular memory card and a professional grade one. The pro ones didn't just cost more and have a fancier sticker on them (although that's what it looked like to me at first) they also yielded faster performance when I was shooting pictures in rapid succession trying to get that elusive "perfect" picture of my kids who like to move faster than the fastest shutter speed on my camera. We're talking fractions of a second in most cases, but with kids who tend to dodge out of the frame before you can snap the picture that fraction of a second is the difference between seeing all of their face or just an ear. So for me, a better memory card means less aggravation in trying to capture pictures of my kids.

A couple of years ago when I upgraded to a Canon Rebel T3i, I also needed to switch from compact flash memory cards to SDHC memory cards. I had purchased a pro-grade one and a SanDisk Extreme card based on reviews that indicated that it was every bit as good as the pro one and in some regards faster. I've been very pleased with the Extreme card to the point that I even brought an additional one because I felt it performed better than the pro one for about half the price. So when I was given the opportunity to review this newer SDXC card I figured I'd give it a try. It claimed to be compatible with major brand DSLRs so I figured it couldn't hurt to give it a try. I've been shooting with it in my camera and it's performing every bit as well as the SanDisk Extreme SDHC (45MB/s) and it's likely a a few fractions of a second faster but I wouldn't know how to test that so I'll take the manufacturer's word for it that it's faster. I was able to capture my lightening fast two year old just as well using this card as I could with my older SDHC Extreme card.

With this 64GB card in my Canon T3i depending on the picture size I select, I can capture between 2200 (RAW) to 9999 pictures (using every setting outside of L [7885], and RAW+L [1745]) on this card.

I'm pleased with the card and like that it has a ton of storage space.

I got this to put in my Nintendo 3DS XL and had Zero issues just pulled the old one out and put this (32GB) in and it worked as simple as that. My system is noticeably faster and loads games in a flash. I was going to get the "old" version but decided why not get the best SD card I could. Very happy with this purchase.

This is a good, mid-level performance, high capacity SD card. Don't let the name "Extreme" fool you, Sandisk makes 6 types of SD cards ranging from Standard to Extreme Pro. The "Extreme" line is the third from the top, with the Extreme Plus and Extreme Pro above this line. Depending on your needs, this may work for you. In shooting with my Sony RX100(II), There was little image-to image lag due to write time. I am unable to immediately preview an image on this camera (I get the writing file message), but that is more likely due to Sony's processor than to the card: The Extreme Pro (the top card) displays the same issue! Of course, at 64GB, there is a ton of storage. On my RX100(II) there is space for nearly 6,000 images. Not even the most prodigious shooter is ever likely to fill it up with still images, however, the real test is video. Again in my camera, the estimated video capacity if 514 minutes, or nearly 8.6 hours - a pretty significant amount of time! A serial number and download is available for a one year subsciption to RescuePro Deluxe, which is software that allows for recovery of lost files. I have used this recovery software before to recover files and works reasonably well, assuming you have not re-written space with other files or done a deep formatting. Sandisk used to include this as an unlimited use download, but now it is limited to one year. I will hold on to the serial number until I have the need to use it!

The SanDisk 64GB Extreme U3/UHS-I SDXC SD card arrived just in time for a photo making day trip. As a photographer I have a serious need for SD cards, especially for my 24MP cameras shooting RAW. Also, although I had not really used the video capabilities of my cameras much in the past, I had recently started shooting more and more full HD travel vids, that really chew up storage. But the biggest issue for me has been write speed. Although I own a number of 32GB SDHC cards, which had performed flawlessly, they were sometimes just a little slow when using burst or bracket mode. There would be a lag before you could hit the next sequence. The prior images had not written completely to storage. This problem has gone away almost completely with the SanDisk 64GB Extreme U3/UHS-I SDXC SD card, that has a much higher R/W rate. And it's easier to spontaneously choose to make HD vids with the 64GB capacity. A great addition to my digital camera and travels. And, of course, you don't have to transfer your images to another device or storage as often, a big help on out of town trips when traveling light. RECOMMENDED.

Great memory for DSLR cameras, I bought this one because of previous experiences with SanDisk products and this one is no different.

As other reviewers have said this little beast is much faster than what it's advertised. Using CrystalDiskMark 3.0.3 and a Kingston G4 USB 3.0 UHS-II rated card reader it shows 73.75MB/s reads and 54.75MB/s writes (sequential).

It is also much better than the Kingston SD10V/16GB 46 that it replaced, that one measured 46MB/s reads and 11MB/s writes (sequential).

My Nikon D5300 in burst mode fills its buffer after a couple of shots (14bit RAW). With the SanDisk Extreme it takes about 2-3 of seconds to flush its the buffer, while the old card could take up to 20 seconds before I was able to shoot again.

In conclusion I feel very happy with the purchase. I can take more photos in burst mode, transfers to the PC are much faster and for the price is a steal.

For the last 8 years I've used SanDisk memory cards for my photography. I do portrait and portfolio work as well as editorial photography for a large utility company in South Carolina and I can't afford the risk of buying cheaper cards.

As an example, I recently had to shoot pictures inside a nuclear plant turbine room for a safety program. It took almost 2 hours to get through security to get the shoot started but the next couple of hours was inside the turbine room which was almost unbearably hot, noisy, and required safety helmets, goggles, and gloves. Would you risk your shots to a cheap card on a job like this? Not me and even if I'm shooting pictures of my grandkids playing volleyball they are just as important.

When I began shooting video on my DSLR I knew I needed to move up to more capacity and better write speeds. Having used SanDisk cards in all my Canon cameras I knew I would find exactly what I wanted from them again.

After tens of thousands of images and now dozens of hours of video I have never had a SanDisk fail.

There are simply no better memory cards than SanDisk. I use these commercially and depend on their reliability. I have never had a SanDisk card failure, even in the toughest of shooting conditions. You also get a free download of their excellent image recovery program, just in case there ever is an emergency. However, after using SanDisk cards for over 12 years, I am well pleased and will buy no other brand for commercial work.

Bought this for my Sony a5100 and it works great. Like other people said the READ/WRITE speed for this card is a lot faster than what the Sandisk says. Also this card is capable of recording 4K quality. Glad I bought this during Black Friday for only $19. I definitely recommend this card for point and shoot cameras, camcorders, and entry level DSLR cameras.
