A solid, reliable card perfect for what I needed.
23 July 2022DrPlankton

originally posted on bestbuy.com

I use this card in an older Pentax WG-1 camera that I use for underwater photography while snorkeling, video or situations where I don't want to risk my Nikon DSLR. It is a 14 mp camera and the card keeps up with the camera even in video mode. In the highest quality mode it will handle more than 12,000 images so it is more than adequate in that regard. Quality seems up to SanDisk high standards and I have had no problems taking it out of the camera and plugging it into my PC to transfer over the photos and video. There are larger and faster cards out there, but this one was perfect for that camera at a price point that made it a no-brainer. You can get larger and faster cards but that speed and capacity would not make a difference in this camera.

SanDisk has always worked well for me and their SDXC UHS-I Card is another impressive product. The memory card offers 64 GB of space and up to 140 MB/s read speed. It allows full HD video as well. If you have a camera or recording device, SanDisk has the finest memory cards you could hope for. Very dependable. I use the SDXC UHS-I Memory Card in my camera and am happy I do. Highly recommended.

This SanDisk Ultra Plus SD card is a good option for compact and mid range cameras. I am using this in my compact camera and the up to 150 MB/sec read speed is enough. I prefer having multiple lower capacity SD cards as opposed to one huge one, so 64GB is perfect for my use. It is important to have a good memory card because if it fails, then hundreds or even thousands of photos and videos are gone. I know this sadly from past experience. SanDisk tends to make reliable SD cards and this card seems to do well so far. The packaging could be a bit more frustration free. I tried opening it by cutting it across the dotted line on the back but ended up having to cut through a lot of the cardboard and then through the plastic holding the card to get it open.

Good, but too slow for photography.
8 May 2021

This is a good, reliable memory card. However, the speed ratings for these cards are a little misleading. The MB/s rating, 130 on the card, refers to the speed that the card can play something back. It is not the speed at which you can record or write something to the card. To find that speed, you need to look for the “V” number. In the case of this card, is is V10, which means a camera can send 10 MB per second to the card. My camera is a 32MB camera. The onboard buffer can hold about 27 frames before it’s full. I take photos of birds in flight, and so I shoot in burst mode most of the time. I can fill the buffer in about 3 seconds, and then I can’t take any more photos until the camera has written enough data to the card to free up enough room in the buffer for ... MoreThis is a good, reliable memory card.

I can fill the buffer in about 3 seconds, and then I can’t take any more photos until the camera has written enough data to the card to free up enough room in the buffer for another photo. With this card, writing at only 10 MB/s, it would take a little over 3 seconds for that to happen, which is an eternity when there is some kind of action going on. For photographers who will be shooting several shots quickly or shooting in burst mode, V10 is much too slow. I’d recommend a V60 card at the very least. V90 cards are fairly expensive right now, but as the tech improves and prices come down, they would be a better option for the future. However, if you aren’t concerned with the write speed of the card, this one is perfectly adequate.

Great Memory Card
24 December 2022

I love this memory card. I think the quality of SanDisk is so much better than some of the other brands on the market. I used this Ultra SDXC UHS-I Card with my Canon camera. 64 GB is enough space for me. I record both pictures and videos and love that it provides up to 140 MB/s. Another great feature that I really enjoy is that this product is Water proof, Temperature proof, Shock proof and X-Ray proof. Exactly what I am looking for as I travel a lot and need to make sure that this card can withhold anything.

Great Product!
29 December 2022

I recently tried the SanDisk - SanDisk Ultra® SDXC™ UHS-I Card - 64GB - SDSDUNB-064G-AN6IN. This is a great product to store pictures or videos, or whatever else someone might need to store! I love the convenience of having my pictures stored in this card! It gives me great quality when I come back to look through them! And I love knowing my pictures will be stored safely for a long time! Lo e the ease and convenience and large storage capabilities!

Great value from the best manufacturer
11 December 2022

Sandisk makes the best memory cards, it’s that simple. I use a DLSR to take a ton of action and nature photos and need my memory cards to keep up. Sandisk Ultra cards are simply the best. They have top tier read/write speeds, massive storage capacity and I’ve never had one fail. Ever. If you care about your digital files, you just have to buy Sandisk.

I just neeeded to know if it was fast and good
20 April 2019

I hope this review helps someone the way I needed help when I was diligently researching which card to buy. So I create content for YouTube and IG and need a really durable and fast memory card. A card the keeps the quality of the photos and videos but still at a decent price. I previously owned the sandisk extreme cards, 2 64gb ones and a 32GB one. I didn’t keep them in the plastic case but instead in a little pouch so of course over the years (about 4-5yrs) they starting deteriorating. The plastic started to crack and luckily I was able to get my stuff off of the cards before they completely quit.While I was looking for a new one, price plus all of the above things mentioned mattered to me the most. So when I saw this card at the price point and with the reviews ... MoreI hope this review helps someone the way I needed help when I was diligently researching which card to buy.

The plastic started to crack and luckily I was able to get my stuff off of the cards before they completely quit.While I was looking for a new one, price plus all of the above things mentioned mattered to me the most. So when I saw this card at the price point and with the reviews and great ratings that everyone had given it, I thought to myself OK let me give it a chance. And I’m so glad that I did because with a price, the speed and the quality is unparalleled. I am actually buying another one right after I write this review. Just to have it before they get hip to it and possibly change the price or it goes off of sale. Even the regular price point is still super low compared to what I had paid for previous cards even on sale.Another concern of mine was asking the bestbuy associates for help in trying to help me determine what the difference was in between these cards and the ones that were more expensive they kept emphasizing speed. They were saying that the speed on this card was not as great as the speed as the extreme cards. And I actually did not find that to be the case I noticed that the speed was probably the exact same if not comparable to the extreme cards that I had before.So for me, hands down, this was the card for me. I kept it and am currently buying another one. Love this little thing!

Works as expected
24 December 2022

I am using this Sandisk ultra plus 64 GB SDcard in my Nikon SLR camera. It works as expected. I find no difficulty installing it in my camera. Recently we have been to vacation and I used camera with this SD card. All our pics were well stored well with no issues. It could store good number of pictures. It kept all the memories safe. Not only pictures even videos were well stored. I would recommend this.
