Customer Ratings & Reviews

I read reviews and saw where some people had issues with other brands working well, so I decided to spend the extra money and get a brand that I trust. It is all the memory I'll ever need for keeping things on my phone and it not taking up all the phone memory.

I was looking for a fast memory card for 4k video recording and for fast buffer clearing on a mirrorless camera, After reading many online reviews that said this card was one of the fastest and most reliable on the market I decided to give it a go. Now that I've used this card this series will be the only mem cards I buy!

I purchased this as card for extra memory on my phone. It has a super fast read and transfer rate and is 4k compatible. It was on sale in store for $80 which is a price you can't beat!

These SD cards are great for 4K filming. You can capture high quality video with exceptional clarity, especially on fast paced activities (motorcycling).

I got this memory card for my Galaxy S8+ unlocked phone.I didn't experience any issues after using it for more than a month prior to this review.

I put this in my Surface Pro 4 for permanent install. It's tested faster than most other brands, but it's also a bit more expensive. this will hold me over until the 256GB models get released. It IS quite fast.

Use these in my action camcorders. Everything-Proof, fast and hold a ton of video. Also helps when Best Buy has them at a great price!

I love this SDXC card—I bought three of them (from Best Buy): for my Surface Pro 3, my smartphone, and my camera and video recorder. I can easily transfer pictures and videos from it to a MacBook Pro too, which I use for editing. I've had the first card for over a year; it performs well without issues (even in a defective camcorder I was forced to use for several months that was eating/destroying other brands of SDXC cards). I trust this Samsung product.

I have several Samsung Pro and Pro+ micro SD cards. I have a 128gig in my newest camera, a Nikon D3300. I haven't tried video, but there seems to be little or no wait time between taking one picture and the next. I haven't tried auto-bracketing or any such. I just shoot one picture after another, at maximum size and resolution and in JPG and NEF versions at the same time, without any apparent wait time between. I have formatted some of the smaller capacity cards as NTFS for doing backups on that aren't big enough to drag out the 2T external hard drives on. They are much much much better that the USB3 flash drives for copying bunches of small files. (The FAT32 doesn't like shortcuts and some other types of files). For some reason the USB3 flash drives are befuddled by small files, but these cards are not! Note that Windows can only do FAT32 up to 32 gig, and you would need a separate utility program of some sort to reformat bigger cards back to FAT32 (to use in a camera or MP3 player, which does not like NTFS).

Super fast in my Moto X Pure edition. Finally a memory card thats fast enough to not even be able to tell there is a memory card in your phone!

Great for additional storage for GoPro unit. Will enjoy using this back-up to capture many great times. Incidentally, this was part of a "package" purchase for the GoPro, my husband did the research, I made the purchase for xmas.

Bought for my surface 3 and 4 and had no issues, its fast, immediate reads and writes, no issues or complaints. says its more durable we will see over time. no complains except the cost but that is expected for this size drive

I get the 80 MB/s read and write while on pc which is perfect for backing up my phone and writing large 4GB+ movies to the card with little time

I purchased this for my Samsung Galaxy S7 phone because I wanted to expand the storage and I was told that the new Samsung phones require type U3 cards due to the transfer speed that the 4k video needs to write directly to the card. I've had it over a month and so far it works great.

Extremely fast transfers Massive storage space Great price

great speed and quality...xlarge storage capacity.

I needed extra memory for my tablet and went with the recommendation of the Samsung rep at the local store. Super happy with memory card.

Installed this in my Samsung Note 8 and have had no issues. Works flawlessly. All pictures and videos go onto this card.

Bought this originally for my go pro. Has great reading speeds and compatible with 4k.

I use it with my go pro, I still haven't gotten to the point the memory is full. A must with action cameras and other devices.
