My benchmark: CrystalDiskMark 5.2.1 x64 with USB 3.0 Kingston FCR-HS4 Card Reader (Average of 5 runs, 1GiB data): Lexar 6333x 64gb, 91.85 MB/s Read, 18.45 MB/s Write, 7.93 MB/s Read 4K, 1.12 MB/s Write 4K Sandisk Ultra 32gb, 45.72 MB/s Read, 11.95 MB/s Write, 5.46 MB/s Read 4K, 2.08 MB/s Write 4K Samsung EVO+ 64gb, 92.47 MB/s Read, 45.51 MB/s Write, 9.21 MB/s Read 4K, 2.31 MB/s Write 4K Samsung PRO+ 64gb #1, 92.06 MB/s Read, 84.72 MB/s Write, 7.46 MB/s Read 4K, 2.93 MB/s Write 4K Samsung PRO+ 64gb #2, 91.86 MB/s Read, 84.10 MB/s Write, 7.35 MB/s Read 4K, 2.91 MB/s Write 4K Samsung PRO+ 64gb #3, 92.48 MB/s Read, 84.51 MB/s Write, 7.28 MB/s Read 4K, 2.91 MB/s Write 4K Note: Any of these cards should be overkill for recording 1080p30 w/ Audio, as well as 3820x2160, 30 Hz w/ Audio (5 MB/s) Based on these results, we can see that the sequential write is fantastic on these PRO+ cards, in addition, random 4K performance is slowly lower than the EVO+ card I had. The reason three cards are there is because I bought 3 separate PRO+ cards. I'm only going to take one star off my perception of this card because of the high price.

Got this card for a good deal. Works great in recording 4K content.

Works AMAZINGLY! Love it and do recommend it. I use it in my tablet and you cannot BEAT THE PRICE FOR PERFORMANCE. This same product specs in some other name like Sony or anything else with 95 read and 90 write speeds and capacities you'll pay 99.00 and I paid at best buy 38 - way cool - now i'm going to buy the 128k to hold all my movies on my tab and pick up an extra one for my laptop. !!! 5 STARS FOR PERFORMANCE, FOR PRICE ABSOLUTELY BUY THIS PRODUCT! THANK YOU SAMSUNG!

Bought this after trying out a UHS1 128gb Sandisk Microsd. The Read and and mostly Write speeds on that were high, but very inconsistent. I bought this and it has worked flawlessly. Tested the speeds via computer and saw very close results as expected and have been using it as an INTEGRATED memory in my Android 6.0 Marshmallow phone. I see no lag when using it to boot apps and such that aren't required to be on my regular 16gb internal memory.

I got this card after comparing it to another name brand card that was selling for a lot more money. This card was purchased with my DJI Phantom 3 Professional drone that has a 4K camera and I must say it works really well. The camera records in 4K at 30 frames per second (fps) so I think it could handle 60 (fps) or more depending on what your camera does. So far I have Been using it for over 4 months and it still works perfectly.

I needed a class 10 micro sd card with alot of gigabytes for my GOPRO Silver to take HD video and pics... It was practically half the price of the other brands with equal specs. I got lucky I found it. I found this samsung micros sd card in the samsung department, by the tablets. For some reason this micro sd card is not available where all the other sd cards are located. Things that make you go, Hmm?

I purchased this MicroSD card for my Galaxy Note 4. It replaced an EVO card that is now in a tablet. This card is extremely fast and I got it for a great price. The only card that comes close is the SanDisk Extreme Pro, and that card is a whole lot more expensive. If you are looking for the best, this is it.

After comparing specs and reviews for microSD cards, this manufacturer and product stood out for sheer speed and reliability. The price point was (past tense) unreal, so I snapped up several for myself and recommended it to friends and relatives. Downloading app data ( offline maps) to my phone was blazingly fast, 4+ times faster than the EVO+.

Great Product Great Price. Plenty Fast. Solid and Reliable

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!

This is one of the best cards I have owned so far for speed and price ratio! This card is perfect for using in my 4K camera and no matter what I take video of, I have zero problems! If you grab this card on sale than this is the card to beat in price to performance ratio.

I got this memory card for our gopro hero4 black. super fast write speed allows us to utilize all the settings on the gopro with high quality and with 64g we were able to use the gopro for the whole honeymoon (including timelapses and scuba videos) with space to spare.

I got this for my GoPro Hero 4. This works perfectly recording any video and taking pics. I don't see any lag or hiccups. Hands down the best SD card in the market. Get it when its on sale. I want to say I got it for $30. You can't beat that.

Was looking to buy a very fast read/write micro-sd card to use with my GoPro Hero 4 Silver. The card is dust proof and shock proof and is able to handle recording of 4k videos easily. Totally recommend for GoPro camera or any other cameras.

I use this card in my Shield TV. I wanted to be sure the read speeds were high enough to support full 4K TV. I installed it formatted it, have been using it, and all has been great. Fastest little cards out there at the time of writing.

This memory card is pretty awesome. I use it as an extension to the HDD on my macbook. Read/Write speeds are amazingly fast and the card itself is water proof. I bought it at half price on a deal of the day sale.

I mainly use MicroSD cards for my GoPro, and DJI Mavic. I saw that this was available at a pretty good sale price, so I purchased two. Their high speed writes are perfect for 4K action cam and drone footage. I've even used it in my Mirrorless Camera for shooting 4K 30FPS @ 100MBs with the included adapter and no problems. Looking for a 128GB Card soon, and I used to lean towards San Disk only, but now Samsung is definitely in the running.

Works great with my HTC smartphone. Transfers data really fast. I use it for music, pictures, and videos. It can handle taking 4k videos. 4k uses up the storage space quickly though.

I am using this Samsung - Pro+ 64GB microSDXC Class 10 UHS-1 Memory Card in my Samsung Galaxy Tab 4 10.1in. And I have had no problems with it. I previously had a Samsung Evo 64GB microSDXC Class 10 UHS-1 Memory Card however that card failed within 1 month. Though that may have been the fault of my Speck brand tab case. Which I believe put to much pressure on the memory card slot. I have since modified my Speck brand tab case by notching out the area that covers the memory card slot. As I have previously stated I have had no problems with the new Samsung - Pro+ 64GB microSDXC Class 10 UHS-1 Memory Card. Everything is working great now.

I don't know much about sd cards but it is a nice upgrade from the 16 gb that we used previously. Got it at a good deal; much better pricing than the Sandisk brand
