Samsung EVO+ 256GB UHS-I microSDXC U3 Memory Card with Adapter (MB-MC256DA/AM) (1 Pack)

I have a Windows Phone - Lumia 950 XL. It has a microSDXC slot. I was previously using a 128 GB SanDisk with up to 30 MBPS.SanDisk Ultra 128GB MicroSDXC Class 10 UHS Memory Card Speed Up To 30MB/s With Adapter - SDSDQUA-128G-G46A.I kept having laggy photo performance. It would take a while to save multiple photos, process them, videos might prevent more photos from being taken. I was at a show recently and had issues where I lost photos and said 'That's it' and made an effort to research SD cards.I've found this to be the fastest card on the market today. The EVO+ line is similar to the PRO+ line made by Samsung. I checked the press release on the most recent 256 GB EVO+ and it brought the read/write speeds up to line with the PRO+, but increased the storage to a whopping 256GB.[...]"The EVO Plus 256GB raises the bar for capacity and performance of microSD cards thanks to Samsung’s advanced V-NAND technology, offering high read and write speeds of up to 95MB/s and 90MB/s, respectively. This level of performance will provide general consumers and professionals with superb user convenience for storing heavy-loaded, high-resolution photography and 4K video recording, as well as graphic intensive multimedia like virtual reality (VR) and gaming.“With the upward trend of consumers using high-performance, high-capacity mobile devices, our new, V-NAND-based 256GB microSD card solution allows us to deliver the memory card consumers have been craving,” said Un-Soo Kim, Senior Vice President of Brand Product Marketing, Memory Business at Samsung Electronics. “Our EVO Plus 256GB microSD card, will provide consumers with large capacity, and high read and write speeds.

Pretty fast for such a big card! If you want faster read speeds but a higher price, then check out the  Lexar Pro 1000x UHS-II/U3  (Think about it, you spend most of your time copying files OFF of the card to your computer. Lexar card saves time!!) Write speeds on both cards are massively faster than you need, even when recording 4K at max settings. Let me explain.The new Gopro 5 Black and Session 5 only writes at 60 Mb/s when doing 4K. This card can write 680 Mb/s (aka. 85 MegaBytes per second)! Plenty fast!10 year Warranty on card, Lexar has lifetime.97.31 MB/s Read - 85.77 MB/s Write on my system, using CrystalDiskMark 5.1.2 (x64) on Win 7 using  Kingston MobileLite G4 USB 3.0 Card Reader (FCR-MLG4) Fully recyclable packagingWorks on the following:GoPro Hero 5 SessionSamsung Galaxy Tab S 10.5Samsung Galaxy S3, S4, S5, S7 and S8Samsung Note 4Microsoft Surface Pro 3Tested with:ATTO v2.47CrystalDiskMark 5.1.2 (x64)h2testw v1.4

Awesome

Under ideal lab testing conditions (not real world use, which is always far lower):Capacity: 238.4 GBRead: 82.0 MB/sWrite: 74.1 MB/sAdvertised:Capacity: 256 GBRead: 95 MB/sWrite: 90 MB/sThe real R/W speeds, which, again, are under ideal conditions, not real world use, are still more than good enough for real time writing of 4K videos or anything else you could throw at it, but still not even close to the frankly unrealistic speeds that are advertised.And this is just my personal ideology speaking, but this whole system of legal capacity reporting VS actual scientific capacity needs to stop. Advertising storage media at one capacity using a completely fake system for calculating capacity while the real capacity is much lower is unethical and wrong, but not one manufacturer seems to see anything wrong with the practice as long as all of the others continue to do it.

I bought this 256GB microSDXC card to replace a smaller slower 128GB card in my Surface Pro 3. I did it for the extra space but wanted better read and write speed. The new card worked exactly as expected. I keep all my files on the card and read and write to it constantly so the performance boost was very important. This card seems to be the perfect fit for my need. A faster, more expensive card would have been wasted money. I got the speed boost and the extra space I needed, should never need more speed or space in the future and a quality Samsung card for a very good price.

I am very happy with this memory card. I bought it to use with my Pono Player, and it works great. I am hoping that Samsung comes out with a 512 GB or 1 TB card before Christmas so I can upgrade my music collection. I have seen some off brands for cheaper, but when it comes to memory cards, I only trust a few. I have also seen a few auctions on eBay for this card at a greatly reduced price, but I am wary that they are not the real deal. The one I bought is genuine.

This card works well in my Samsung Galaxy S5, its nice to have a good amount of my audio files on my phone and still have a little room left for pics and vids!I've had this thing in my phone since November of 2016 and have has zero issues with it, even though I have about 210gb of audio files on there the whole time.I use my phone for audio (mostly flac files played through winamp) streamed to my 3 vehicles, as well as bt earbuds when I'm on a jobsite, never an issue even when the phone is roasting hot!

Me gustó todo, no puedo mandar foto porque está en Uso

Perfect for me. I used this 256 gb microsd card for backup of my ipad 4. Works perfectly so far i used it with my usb3, iplugmate.Copying large photos files 80 gb take few hour but i don't mind . I try the speed test online and writting time is 38 mb/s and reading time is 85 mb/s. Not bad. Pricie but very good.

nice & orginal product happy with it but amazon deliver boy talk v rude & telling also cancell d prdouct

Came earlier than expected. This product was genuine and works flawless in my mobile phone. Transfer rates are decent, but not as advertised. My major concern was this was REAL and it was. Will order again from this vendor.

Quality is very good. thanks for Amazon team.
