Samsung PRO Ultimate Full Size 256GB SDXC Memory Card, Up to 200 MB/s, 4K UHD, UHS-I, C10, U3, V30, A2, for DSLR, Mirrorless Cameras, PCs, MB-SY256S/AM

Great value, for this SD Card, I know most will rave about SanDisk and Lexar, but these Samsung Pro Ultimate do every bit as good a job IMO with better speed in my case, and for the price (under $40) with the card reader (which I actually use a lot), it's just a great value, I plan on buying a couple more as I use them to backup large music recording sessions.

Great performance/fast

It has been 2 years since I ordered this and it has no issue. Good writing speed and comes with USB adapter. I love this memory card.

I purchased this to be used as GD-EMU storage for my Sega Dreamcast (VA1, the original release in the US). Swapped out my GD-ROM and replaced with a SD Card reader in a 3D printed GD Rom mount. It works without issue on my Dreamcast. I stored 70 games and I'm barely 1/4 full on this card.

I've been using the Samsung PRO Plus Full Size 256GB SDXC card for a while now, and it has consistently proven to be a highly reliable and efficient storage solution for my demanding photography and videography needs. While it's not a perfect 5/5, its strong performance, particularly in data transfer rates, makes it a solid 4/5 in my book. This SDXC card has become my go-to for capturing high-resolution photos and 4K video. The 256GB capacity provides ample space, allowing me to shoot extensively without constantly worrying about running out of storage, which is crucial during long events or travels. Where this card truly shines is its data transfer rate. Whether I'm offloading hundreds of RAW images from a photoshoot or transferring large video files, the speed is noticeably impressive. It significantly cuts down on the time spent waiting for files to move, which is a huge productivity booster. This consistent high-speed performance ensures that my camera's buffer clears quickly, allowing for continuous burst shooting without interruption, which is essential for capturing fast-paced action. I've used it across various devices, including my Canon R8 camera and a high-speed card reader, and it has maintained its excellent performance. It feels robust and well-built, giving me confidence that my valuable data is secure. The reason for the 4/5 instead of a perfect score is minor, perhaps just a slight wish for an even more competitive price point, or maybe some additional extreme durability features, though it has held up perfectly fine under normal use. For the vast majority of users, this card offers an excellent balance of speed, capacity, and reliability. In conclusion, if you're a photographer or videographer looking for a dependable, high-speed SDXC card that can keep up with demanding workflows, the Samsung PRO Plus Full Size 256GB SDXC card is an excellent choice. It delivers on its promises and provides a smooth, efficient experience.

Samsung cards are good quality. I use them in my Nikon. Never had an issue with them.

I have bought dozens of these cards and basically keep them on a long rotation (and implicit backup). Transfer speed is great, reliability is perfect, and the white plastic housing makes it easy to see in a camera. Cost-effectiveness is great, and in terms of ease of use, they cannot be beaten.

Purchased for a digital camera and works perfectly. No issues with pictures or videos.

Great UHS-1 SD card.like the 128 gb card i bought before.Get the one with the card reader,you will get faster read speeds.Highly recommended.

Tested with H2testw. Using the packaged USB reader, and plugged to USB 3.0 on my PC. Read 170 Mb/s. Write 125 Mb/s. Good enough.

Parecen funcionar correctamente y aparentemente pueden ser un poco más veloces de lo anunciado. Pero tienen un detalle, el cuerpo de plástico del adaptador es exageradamente ancho por lo que es probable que no entre completamente en algunos conectores en donde pueda estorbar con algo que tope con los bordes de plástico del adaptador. Al conectar en un puerto USB 3.0 de tipo frontal instalado en un lector multitarjetas el conector no pudo entrar completamente por lo que arrojo veolidades muy por debajo de lo que deberia (Un maximo de 40mbps de lectura y poco más de 30mbps de escritura), al corregir el error o conectar a otro puerto libre —volvi a conectar en el mismo puerto luego de solucionar lo que estorbaba con los bordes del adaptador— la velocidad alcanza el maximo prometido, de lo cual muestro imagenes. DETALLE IMPORTANTE: Son memorias SDXC DE TAMAÑO COMPLETO, NO son microSD por lo que no son compatibles con Smartphones y la mayoria de Tablets, puede haber errores al comprar creyendo que es una microSD que incluye un adaptador USB, en parte porque el menu desplegable de la pagina legible muestra exactamente las mismas palabras "Nueva Generacion de tamaño completo P..." y como se puede acceder desde la pagina de la que si es microSD y como indica la misma leyenda (en lo legible) se puede llegar a creer que la que incluye del adaptador USB es para el mismo tipo de memoria.

The best SD UHS-1 card i ever had,better or equal the best Sandisk UHS-1 i have.Highly recommended.

ممتاز
