    Conclusion The Samsung SD Pro Series line is optimized mostly for photographers and enthusiasts that require superior performance from their flash cards in order to more efficiently capture, transfer and edit their images. The Pro Series SD cards range in capacities, starting at 16GB, hitting 32GB for the maximum capacity of the SDHC format, and peaking at 64GB in SDXC format. What really drives the Pro Series SD cards though, is their robust performance specs which Samsung quotes at 80MB/s for read activity and 40MB/s for write activity. The cards also feature UHS Speed Class 1 and Class 10 video recording ratings, ensuring that users will have optimal read and writes even with HD video. The Pro Series SD cards are also water, shock, magnet, X-ray and temperature proof. When it came time to test the Samsung SDXC Pro Series, it performed quite well, nearly matching the same figures at which Samsung quotes the flash card. Sequential performance for the 64GB card was at about 75MB/s for read activity and 38MB/s for write activity. When we tested the random large-block performance of the Pro Series, it delivered about 67MB/s for reads and 7MB/s for writes. These numbers were near-identical to the 32GB Pro Series we also tested. When comparing this card to the Lexar Professional 600x SDXC UHS-I, the Lexar provides slightly greater performance (anywhere from 5-15MB/s better), yet it does so at around double the cost of the Samsung. So while the Samsung is limited to 64GB (versus 256GB on the Lexar), it still provides a really good value at its price point, and it's easy to envision consumers opting for the Samsung SDXC Pro Series.
