DO NOT BUY! COUNTERFEIT CARDS BEING DELIVERED!I purchased 3 of these 256 GB 170mb/s SanDisk Extreme Pro SD Cards in April for the upcoming Wedding Season (I'm a wedding photographer.) 2 of the 3 cards were used and both of the ones I used corrupted image files. 1st wedding I lost about 200 files. 2nd Wedding I lost about 50 files. 3 use I lost 10. Once I realized I had corrupted files, I immediately changed out my SD Cards. Upon further inspection of these new cards (which I have had to replace because I refuse to use this again for fear of loss of work) the SD Cards do NOT have a Serial Number on the back of the card, the plastic feels different, the contact points on the back of the SD Card are a different color or form of metal alloy, and the ejection tab on the ... MoreDO NOT BUY!

I'm just so angry for trusting Walmart.com with my gear needs. I would honestly give these a 0/5 stars if I could!

Excellent Memory Card with large capacity. My daughter and I take a lot of pictures with my Nikon D3500 Camera. We switch the memory card between my Nikon D3500 camera, HP Spectre laptop and a Mac Laptop when loading pictures to eBird. We have never had a problem with the Memory Cards and buy the same kind all the time. Highly recommend this brand and capacity of Memory Card.

I have never had a problem with Adorama, but I checked the back of this card anyway and was relieved to see the product code on the card, assuring me that the card was genuine. I purchased a card on Ebay that looked exactly like this one, but there was no product code on the card and when it died after a month, applied to SanDisk for the warranty and found that the card was not a genuine SanDisk.Having said that, be sure to purchase from a reputable source. Adorama is a good source and SanDisk is a reliable, quality card. This one is still performing flawlessly..

Pros: I needed a memory card for a new Raspberry Pi 3B. The adapter fits my multi slot USB card reader allowing me to download the OS. The adapter can then be discarded and the memory card fitted to the Raspberry Pi. Its performance and reliability are great. I often leave it running for days on end.Cons: No.
I have used the 64GB version of this memory card for several years, sometimes used in pairs for mission-critical photography tasks. It is fast enough, or more correcty has adequate bandwidth, to keep up with my DSLR's fast shutter mode and video shooting tasks. Admittedly, I don't shoot a lot of video and only at 1080p @ 60 fps. There are slightly cheaper alternatives, but given that this card is (theoretical) 95 MB/s throughput, the online purchase cost of this 32 GB version is very reasonable. I have never had a failure of the 64 GB version while used in my DSLR. Over time, I have developed a trust of Sandisk memory products.
I have been using san disk cards in my camcorders for the past 10 years and am hooked on them. I also have a Nikon D5200 camera that is a workhorse that I use for local band photoshoots. I was using a 32gb sd card that once I would pass 500 shots taken the camera recovery time between shots would get slower. I knew I needed more memory and when I saw this card on sale I immediately ordered one. Once it was delivered I installed it in my camera ready to use the next day I had a photoshoot to do. To my surprise and happiness, this card was a godsend to me. Snap the shutter and the camera was ready for another shot almost instantly! It worked this way even after taking over 600 shots with no indicator of slowing down! I am in love with this one. If you get the chance ... MoreI have been using san disk cards in my camcorders for the past 10 years and am hooked on them.

I use SD cards for many different purposes - some personal and some business - and mostly for photography. I want to make sure that I am using the real thing not a knockoff. There are so many fakes out there that it's a real risk and that's especially true if the cards are cheaper than you'd expect. Buying direct from the source gives me peace of mind that my cards are genuine and will not let me down.The cards are indeed reliable and live up to the specs that accompany them. I have never had a genuine SanDisk card fail on me. They have always done what I have asked of them.Highly recommended for anyone who needs SD cards.
Product reliability, durability & quality assurance makes purchasing the SanDisk brand a no brainer. I bought a couple of these for my Nikon D7000 and are more than adequate for the camera. Just a heads up on buying the correct card for your camera. Do your research. A faster card only means faster transfer rates - if your camera is designed to handle them, excessive speeds are a total waste. Only buy the nearest compatible rated memory card for what you own. Example: The SanDisk Extreme Pro 45MB/s SD HC 1 card was specifically made for the Nikon D7000 - as it was the only DSLR digital camera capable of processing such speeds at the time of production. Because these are no longer available, I always try to purchase the nearest MB/s that is available, in this case, ... MoreProduct reliability, durability & quality assurance makes purchasing the SanDisk brand a no brainer.

Example: The SanDisk Extreme Pro 45MB/s SD HC 1 card was specifically made for the Nikon D7000 - as it was the only DSLR digital camera capable of processing such speeds at the time of production. Because these are no longer available, I always try to purchase the nearest MB/s that is available, in this case, 95 MB/s. A faster memory card will provide no benefit to your cameras speed. It works like a bottleneck. When the camera takes a picture, the sensor captures information and passes it to the buffer, and the buffer passes the information to the memory card. If the processor in the camera is slow, using a faster memory card wont make a bit of difference in speed. In many cases, however, the memory card is the weak link in the chain.
Bought two of these to go with my Canon R6. Have so far shot about 4000 raw pictures and about 40mins of 4k video. Absolutely no complaints. At 20fps shooting RAW I have had no issues with the camera buffer. Although the R6 buffer is very large. Video has been rock steady although I have yet to try more intensive formats such as 120fps. When transferring files to the computer the card is no slouch operating at around 90-100mbs through a USB hub. I don’t feel frustrated by the amount of time it takes at shifting 50GBs worth of data. I would highly recommend going for the 170mbs cards as the 300mbs are another level in terms of price.
I purchased these for a safari trip which gives me lots of capacity for taking action photos. I like to have several smaller memory cards in case one gets corrupted rather than a single larger card. The write speed is ideal for my system (Canon 7d mark 11 and using a 100-400mm IS 11 USM lens) . I may need to consider different cards if I ever go to a different and/ or mirrorless system.
