Incredible Value with Great Performance
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.

Fast enough for JPG use.
I use this card as the JPG half of a RAW+JPG pair, with a CF Express card in the other slot. This card is fast enough to keep up with 20FPS on 45MP writes, which makes it good enough for me! The included adapter was a lovely touch. Feels very high-end; very smooth plastic, solid construction. An instant backup addition to my bag.

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.

This UHS-! Sd card is rapidly becoming my favorite sd card outside the best UHS-II V90 cards like the Sandisk Extreme Pro and the Prograde.This Samsung card performs like it should and the controller seems to be excellent,the write speed is very consistent.Highly recommended on it's own but i would suggest you buy the card with the card reader instead of the card alone.The Samsung reader gives a boost in read speed just over 200 Mb/s.See the photos were the higher numbers are set with the Samsung card reader and the lower values (still very good) are with the Prograde card reader.

Adquirí esta tarjeta y ver si mi Panasonic HC-X1500 la reconoce. Y lo hizo!!. También la probé en la Sony FDR-AX43 y la reconoció. La probé en la Sony A6100 y la reconoció sin ningún problema. Finalmente la probé en la Nikon Z 5 y la reconoció. Incluso fue igual de rápida que mi tarjeta Lexar Professional SDXC UHS-II que tengo instalada en ésta cámara. Hice disparos en modo ráfaga para comparar la velocidad. Es muy recomendable.
