This product fails miserably to deliver expected high speed transfers. Samsung claims file transfer speeds are UP TO 130 Mb/s. Technically, this is true, but only because any number between 0 and 130 can be considered UP TO 130. The reality from my experience is a high of 23 Mb/s, an alarming 107 Mb/s slower than the potential highest speed. Yes, I know many factors have to be considerd - internet connection, computer,etc. While my setup is far from superlative, it is certainly capable of file transfer speeds of up to 130 Mb/s. I use a Lenovo IdeaPad 3. Connection is Xfinity Broadband with speeds up to 300 Mb/s. My computer and one mobile phone are the only devices connected to the network. One star out of five is a generous rating - 20 percent of a perfect five ... MoreThis product fails miserably to deliver expected high speed transfers.

One star out of five is a generous rating - 20 percent of a perfect five star rating. The product itself delivers less than 18 percent of its alleged potential (17.69 percent of its alleged top speed). I am impressed by the enormous storage capacity (477 GB) but that is overshadowed by its dismal speed performance. Overall, performance was most important to me with this product, far outweighing features and design, resulting in a deserved one star rating. I will credit Samsung for its phrasing of "UP TO" involving transfer speed. It is not a lie, it's just unlikely to happen. In the same context, everywhere is within walking distance if you have the time.

I have used Samsung products for a long time and this Micro SD card is just another great product to have. I have a Samsung phone with the expandable Micro Sd card slot and with this card it is much faster than the previous versions. I take a lot of pictures and videos and 512gb is the minimum I needed to use when I am on vacation. When I am on vacation I sometimes do not have access to the cloud and using the expanded memory it gives me the freedom to take both pictures and video without a worry of running out of space. I also have an action camera so if I am doing an activity as scuba diving, parasailing or anything in between, this card has enough space, it is fast as well to keep up and I do record in 4k.The card is reliable and works great.

*I received this product for a discount in exchange for my honest opinion.* I purchased this to replace an older (several years older) microSD card that I used in my original Nintendo Switch, which I replaced with the new OLED version. Since most of my games are digital, I was experiencing lag with the older card that is essentially non-existent now with my new EVO Select + Adapter microSDXC card. I couldn't be happier. I did a side-by-side comparison with some of my games and noticed a big increase in improvement with the newer card. The transfer speeds were smooth and fast while moving from card-to-card via my laptop. Samsung has always been my go-to for microSD cards and they continue to impress me with this new card.
