Bought for my Nikon DSLR Camera

I bought two of these 64GB Memory cards to replace the two PNY Memory cards I was previously using and had started to fail. I couldn't even take anymore pictures with the old ones without them erroring out on my Nikon DSLR Camera. I thought I might need to get the camera repaired or buy a new camera altogether. Fortunately for me, Amazon had a sale on these memory cards over the holidays and so I bought two of them to replace the old two. I was taking a chance that it was just the old memory cards that were causing the camera to no longer be able to take pictures . . . and I was right, thankfully. It was a lot cheaper to buy these cards and replace the old ones than to buy a whole new camera, as I'm sure you can imagine. So far, we have used the camera with these new cards a handful of times and they have performed flawlessly - no issues whatsoever. I'm quite pleased with the new memory cards and definitely recommend them. I realize that there may be faster memory cards out there, but my camera is a few years old and wouldn't take advantage of the higher speeds. I'm more of a casual photographer for family events and social gatherings. So for me, these cards were perfect and I'm very happy with them. 5/5 stars and no complaints at all. If anything changes, I will update my review :-)

The Ultimate Line of SD Cards for maximum performance

The ultimate in SD cards of not only Sandisk but above all other companies when it comes to UHS-I (and UHS-II for the UHS-II version of this). Time and time again I have relied on Sandisk to record my images and video for personal, paid, professional, etc. events where I need reliability and I don't think I've had a Sandisk memory card ever fail on me save for one non-Extreme model that was very old and in a newer camera. Its speeds are superb and they match what they advertise. I really can not recommend this brand and this line of memory cards enough. They last too. I have several older Extreme Pro's that function just as well today as ever with no reduction in reading and write speed despite being used for applications with constant read and write and constant formatting. I have used these cards to shoot both RAW stills and video, the latter of which is a VERY stressful and demanding task for a camera to ask for a memory card, the memory card must maintain a truly stable and constant write speed and Sandisk does where other brands do not. I have used other brands and yes they work but for shooting high speed, high megapixel stills cameras or shooting 4K video or RAW video I will use Sandisk whenever possible. They continue to exceed my expectations and you truly get what you pay for and then some more. If anyone has any questions, feel free to ask. I use these cards daily and have for a while.

Makes new camera even faster.

I did a review on how much faster than card makes my camera write after taking a photograph, which means I can take them faster in succession now, than I have ever done before. Well, I have a new camera FZ-80 (which is great), but noticed that even though it would takes photos faster than the FZ-70, there was a noticeable lag time before I could take the next photo. So I am ordering another one of these cards, for the new camera as well. If you are somewhere where you need to take a series of photos quickly, like trying to catch a setting sun, this card will make a difference

Excellent card but remember there are a lot of fakes out there so please read this

Excellent SD card. read and write performance are within (grain of salt "within") stated performance expectations. Please try to double check to make sure you're not getting a fake card. The real cards have very little printing on the back of the card and the lock level should be grey; most fakes I've seen have a yellow lock level. The fonts are also different on the fakes card; you can see good examples of real vs fake cards on youtube.

Great Cards

Update 12/18/18: Sony released a firmware update that fixes this issue. I have no idea if it was a Sony problem or a Sandisk problem, but it works now. Original Review: I had purchased some of these cards last year and they work great. When Amazon had a sale on these a few months ago, I picked up two more. Unfortunately, Sandisk made a change to the controller on this batch of cards, and neither of them work in slot 1 of my A9 or A7iii. Disappointingly, Sandisk's recommendation is to return them and buy the (more expensive) UHS-II cards, but I've already passed the return period. I can still use them in slot 2, but it's unfortunate to have this kind of limitation. Hopefully either Sandisk will publicly acknowledge this issue soon and replace the affected cards, or perhaps Sony can fix the issue on their end with a camera firmware update (though the A7iii firmware was recently updated, and did NOT fix the problem).

BEWARE OF FAKES! YELLOW LOCK TAB? RETURN IT!

***Second Purchase (FAKE Card) - May 2018*** As you can see below, I purchased the first card from this same listing on Amazon and it was real. Unfortunately a year later I purchased the same card from the same listing and now I received a fake. I noticed the box had some hard to read print on the back, but didn't think much of it. Then upon opening the card I noticed that the locking tab was yellow, not grey like my first one. Upon even closer inspection, I noticed that the new (fake) card didn't have a batch/serial number on the back, and was missing the "Made in China" engraving. Once formatting in my camera and testing, I noticed that the card easily took 10 times as long to write a photo to. Also, the camera was saying that the new card had a higher capacity. As I am using these cards in a Sony A7Riii, and the fact that it takes 100MB 43MP photos, I require high speed cards, hence why I purchased the fastest UHS-I card Sandisk makes. Amazon in the past has provided real cards, but in this case it was fake! To the untrained eye or average consumer, most will not notice this until they have VERY poor performance from the card, and may think it's their camera, device, etc. See below for test and comparison photos. ***Original (Real Card) - June 2017*** I used this card in my Sony A6500 for about 8 months shooting about 20,000 RAW images without a single issue. I've now upgraded to the Sony A7Riii and am getting great read/write speeds in-camera with it. As some may know, the camera has 2 card slots: one UHS-1 and the other UHS-2. UHS-2 supports triple the speeds over UHS-1, which is what this card is. I still get more than acceptable burst rates before the buffer fills. I see no reason to ugprade to the twice the price, half the size UHS-2 cards for this camera.

More capacity for the money (but also slower than the Pro 300)

My review isn't to squash this product at all as I shoot both photo and video on my Sony a7Riii for a living so it's critical that the memory card can keep up. This UHS-I card definitely is worth the money and may be overkill for most shooters unless you're shooting 4K videos and need a memory card that can clear the buffer relatively fast. My results are based on two of these cards as I need backup as I travel and the last thing I need is two cards going bad...I rather have extras on hand (as much as I've yet to have a memory card fail me for over 15 years). With my Sony a7Riii, I was able to continuously shoot 10 minutes of 4K, 24fps (at 100MB/s) as shown on the file. I'm glad both cards were legit as I usually don't buy memory cards from here with all the horror stories. Gray tab tested good but the only thing I couldn't test is the actual read/write with the real UHS-II & I card reader which I don't currently have and is on order. With that said, yes, for 4K shooters, this card will shoot just fine at full uncompressed 100MB/s setting. Now if you shoot sports or have high-end DSLR's and mirrorless, this is based on my test tonight but here's the result between this and the two Sandisk Extreme 128GB PRO (about $200 each ugh). Burst shot results with this card: 30 shots (at 1/8000") on my a7Riii, 39 seconds to clear the buffer Burst shot results with Sandisk Extreme Pro 300, only 17 seconds to clear the buffer So it depends on how much you shoot in burst and how often. Obviously, if your camera has lower resolution and doesn't shoot continuously, this card should be more than enough considering how expensive the Pro 300 is. In fact, I don't feel like I take full advantage of the Pro 300 as I currently don't have the UHS-II card reader as much as I shoot a lot of videos these days. If you have any expensive camera, get the best memory cards. I've yet to have Sandisk memory cards fail on me (knock on wood). I just can't use Samsung as Sony doesn't play well with Samsung cards as confirmed by other pro photographers & filmmakers. It's odd...

This card is FAST!

Wow this card is fast in my Canon 7D mark II. I was using a PNY Elite Performance card (rated at an equal 95 mbs) and with my shutter at high speed 10fps I would get 13 frames before it started buffering. With the SanDisk I get 25 frames and the buffering clears quickly. When it hits it's limit it only hesitates a second and starts taking about 2 -3 fps while the PNY card just froze up trying to write. This card even out performs my Lexar Professional 120mbs Compact Flash card. It can record 21 frames before the buffer fills and starts hesitating with it. I have the 160 mbs SanDisk Compact Flash card on the way and can't wait to see how fast it is!

Great Card

This thing is amazing in my Canon T6i! I made the mistake of purchasing a class 4 SD card for my camera and it was alright until I went into continuous shot mode taking RAW photos. It would take six shots and stop with a "Busy" screen preventing me from doing anything else until it was done 20 seconds later. With this 512GB Sandisk Extreme Pro SD card, when I tried the same thing, it took six continuous shots, then proceeded to take more shots less than a second apart... until I let go. I tested this for up to 50 photos and buffering still only took six seconds after that before all the photos were written on the card. Speed and size makes this thing unbeatable. Now if they could only drop the price a bit...

Great SD Card... BEWARE OF KNOCK-OFFS

I have long purchased SanDisk SD cards because of the speed and reliability. However, my most recent purchase of the Extreme PRO 128GB card was unfortunately a knock-off as it was not recognized by the Black Magic Pocket Cinema Camera I bought it for. I searched reviews and indeed found another customer who got a knock-off instead of the real deal. SEE THE PHOTOS TO HELP YOU RECOGNIZE THE FAKE CARDS. I returned the SD card and received the real thing two days later and it worked just fine. I would suggest testing SD cards in the intended device immediately upon receipt, as the fake card was recognized by my computer -Mac- without a problem, and oddly showed a capacity of 134.7GB -red flag-. Had I simply stored the card I probably would have missed return by date. Amazon may need to better scrutinize their suppliers. I don't think they would knowingly sell knock-off products.
