Customer Ratings & Reviews

Needed 64 more gigs, bought this now I have it. Fast transfers and play speed and it formats easily with minimal lost space. Not the cheapest and not the most expensive but I feel comfortable having Samsung in my Samsung and so far I am very pleased. At the end of the day whether you buy this or sandisk you'll be happy as long as you get the higher rated cards.

I grabbed this card over the holidays while BB had it on sale, nearly 50%. It's one of the top rated cards in the class 10 & UHS-3 range. FYI, the card is UHS-3 rated but BB has it labeled wrong in their description as a UHS-1. I read a guys review over at Amazon and he tested a bunch of cards, and this card was the top card in all the read/write speeds.

A good, fast card. While I was unable to get the speeds advertised, I came close - approximately 88MB/sec read and 84MB/sec write. However, I know that different readers will often vary slightly in their USB 3.0 speeds. I only tried the card in one reader and I have no problems with the manufacturer's specs. I would definitely recommend this card.

Speed are most important! Read and Write speed for my camera are a must for 4K video shoot, allowing me to shoot continues 30 minutes plus clips with out fail. Sadly it's Samsung...

Great buy for the price, also very reliable and stable.

I use this card in my Nvidia Shield TV and find it works well. At this time I don't have a 4k TV, so I am not able to test it at 4k. However, it is a U1 card, so it should be able to play and record the video with no issues. I see this card as being a bit future proof, but I know faster is always just around the corner.

Fastest Random Write: Samsung Pro+ Best overall: Samsung Pro+ and Sandisk Extreme Pro Other observations: Performance and price are not proportional when it comes to selecting a microSD card. Some of the worst performing cards in this review also happen to be the most expensive. Not all 633x cards are created equal. The two cards reviewed from Lexar and Transcend are both marked as 633x but vary in performance greatly. 4k video recording using action cams and drone cameras have a typical bitrate of 60mbps or 100mbps, corresponding to 7.5MB/s to 12.5MB/s. All cards in this review should theoretically be able to handle this usage easily. Using microsd card as supplemental phone storage potentially could benefit from a faster card, Best Looking Card (if it matters): Sandisk Extreme Pro: Red/Gold with white print Lexar 1000x: White/Gold with Black/White print Samsung Pro+: White/Black with a red stripe and Black/White print PNY Turbo: Lime Green/Black with Black/White print

The Samsungs sd card is one of the best, if not the best, on the market. High speed, high performance, and affordable. A must have for people starting video recordings

I got this SD Card for my Nvidia Shield TV (amazing btw) and have not noticed any difference in speed/loading times of all the programs I moved to it. If the price wasn't so high (justifiable) than I would always buy these cards as they really are amazing on read AND write speeds!

I specifically needed something that could read/write at very fast speeds for HD video on my HTC RE camera. I researched all the coding and specifications used to identify with the fast read/write speeds associated with some memory cards. This fit the bill entirely. Very happy!

Did a lot of research before my purchase and this seemed like a no brainier. The write speed is fast and the card quality seems great. For the price you get a brand name and super fast write speed. Haven't noticed a significant different between this and a San disk card I have.

I only purchase Samsung and Sandisk cards for my electronic devices. They have never failed me. Typically, Samsung has these cheaper compared to Sandisk, but when Sandisk do go on sale....They would be my first pick. You can't go wrong with either one!

Read the reviews about this microSD card and others. Someone else did the comparison chart homework. This card was right up there with Sandisk Extreme Pro in read/write specs. I use them in my GoPro cameras for recording HD videos. No problems.

This is, by far, the fastest micro s/d card on Planet Earth!! If you are a music freak like me, do yourself a solid and purchase this accessory for your Samsung Mobile Device!! You won't find it cheaper and get it quicker than BEST BUY!!

I'm using this with my Samsung S7 Edge. It's the fastest micro SD card class you can get, and it works really well - as fast as or close to internal storage. Unlike some other micro SD cards which give errors on some phones including the S7 Edge, and/or show unnecessary notifications all the time, this one doesn't. It's reliable, and very good. Especially if you're using it with a Samsung device, I'd strongly recommend it, but either way - it's an excellent micro SD card. I've had many others. This is the best I've had so far.

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 bought this to use in my Surface 3 as extra storage. This card is much faster than the previous ones I have purchased. Still a bit expensive for flash media, but a good price compared to other cards in its speed class.

When I got my Hero4 I did not realize that it did not come with any memory. I bought 2 of these for my GoPro Hero4 Black and have been great. The best part was that order them online and picked them up within the hour.

I am using it on my DSLR camera, and I can feel it faster on reading and writing than other SD cards that aI have used before. It has a lot empty space still, so I dont know how it will behave when it is almost full

I searched for a memory card for my new Hero5blk. All reviews pointed towards this samsung 64g or higher pro+. Installed it and no issues automatically started using my GoPro instead of waiting for SanDisk to fix the bugs on their memory cards or having to reformat it to correspond with the hero5. Im not even close to a tech guy so Don't even waste your time and just go straight to the Samsung pro+, install, start filming! works perfect and is flawless. Ty Samsung
