I love SanDisk cards and use them exclusively for my photography. That said, regarding this cards in particular: 1. Beware the price. This appears to be Best Buy's version of the SanDisk Extreme SD card (same specs, class 10, 90 mb/s, etc.), which is significantly more affordable. Best Buy price matched this for me, but it appeared to be an exception to their policy, considering my significant knowledge about the product. 2. I don't know if this is an anomaly or not, but these cards seem to be just the slightest amount thicker than my other SanDisk cards, meaning they rub just a bit when ejecting. It was enough to make me think that the spring on my memory card slot was giving out. Again, might just be an anomaly.

I bought a couple of these for a safari in Africa. Got the larger capacity because they will allow me to shoot lots of pics and Videos with my new Sony a6000 cameral. Nice feature is the lock switch too. Once the card is full, i can throw the switch to remind me that the card has pics on it so I don't accidentally reuse it and lose the shots on it. Based on my experience, SanDisk is a reliable vendor. Spend a few more buck for a higher quality, higher speed card. Over the life the the card, the difference in cost is negligible compared to the potential for problems with lesser brands.

I've used the SanDisk Extreme Plus SD cards for several years now and picked up this Pixtor card when the other was out of stock. They have the same higher speed ratings which I need for my photography when shooting 10 frames per second or video. I got the 64GB card when it went on sale since the price was too good to pass up! So far I see no difference between the Pixtor and Extreme Plus versions of these cards. I'll post another comment if I find any difference in performance.

Ive bought lexar cards before and lets just say they are not reliable to say the least. I moved over to San Disk and they work like a charm. This card works great for when you are shooting continues shots on your camera and transfers file fast to your desktop within seconds. Definitely would purchase again and San Disk offers a data recover download software for free with the purchase of this card which adds a sense of security. Not sure how reliable that software is and don't want to find out. Lets hope these cards last a long time. lol

There are only two things about an SD card that we care about: it has enough space to store our stuff and it doesn't cause the camera to stop recording due to being slow. This card is fast and spacious. At 100Mbps bitrate (Panasonic G7 4K video) this card holds 96 minutes (1h36m) of video; lower bitrate cameras will hold more. I have yet to have one single instance of the recording failing due to card slowness. I use this card in several 4K-capable cameras and I can say nothing bad about them. Definitely recommend this card!

It is absolutely worth spending a little extra to get a memory card in the SanDisk Pixtor series. Two memory cards with 64GB capacity sitting side by side may look the same, but the Pixtor line will write your images and video to storage much faster than a bargain SD card. When shooting sports or 4K video, especially, you don't want to wait for your memory card to catch up to your camera. I'd rather spend a little more up-front and enjoy my photography, than get a cheaper card and just be frustrated with it.

I do videography as a profession and I figured this card would hold up to what I needed. Unfortunately, it's not really as fast as you would be lead to believe. I occasionally get dropped frames and chop when shooting 120FPS with this card in. It's enough that I swap out for a better card when I have to get the high framerate shots. Overall, it's adequate for the average shooter but if you're doing high end work, be sure to test it thoroughly with your camera to make sure it will keep up.

I purchased a (beautiful) Canon T3i and just at a critical moment: making a movie of my granddaughter's Xmas school play, I get an error message. Fortunately, I had my smartphone with me and was able to capture most of the program. Camera buffs told me that the SanDisk card was needed to give the camera enough memory to make movies. This card is super fast with enough space to capture movies in 1080p. I'm happy with it. Prices, class, and data amounts vary on these cards and they can be rather pricey, so do your homework.
