Review: Samsung PRO 32GB SDHC Memory Card 90MB/s

Samsung PRO 32GB SDHC Card Samsung PRO 32GB SDHC Card Back


The Samsung PRO is new for 2014. It is the highest level of Samsung's SD card line, now consisting of PRO, EVO and Standard. The new PRO is not to be confused with the earlier Pro Series cards which were grey plastic with a brused metal label. The new PRO cards are made of white plastic with a mirror silver label. The old Pro Series were rated at 80MB/s read and 40MB/s write. The new PRO is advertised as 90 MB/s read and 80 MB/s write.

According to Samsung, the PRO is for professional photographers. With high performance and competitive pricing the PRO cards should appeal to enthusiasts as well. The PRO is vailable in 16, 32 and 64 GB capacities. It is rated UHS-I Grade 1, Class 10 performance. We test the real world performance of this card in a variety of cameras and card readers.


What's inside? The PRO series features Samsung's NAND flash MLC memory. Multi-Level Cell (MLC) stores two bits per physical memory cell. The EVO and Standard series use Triple Level Cell (TLC) flash which stores eight bits per cell. TLC is less expensive to produce because it uses less material. MLC is more expensive and requires more raw material, but results in higher read and write speed as well as a longer lifespan (in write cycles). However both types of memory are capable of thousands of write cycles and should not be an issue for photographic use.

Testing the Samsung PRO SD card

We subjected the PRO to a variety of tesets. Beginning with benchmarks which show its maximum read and write speeds in various card readers. It performed very well and surpassed its stated speed ratings. In our fastest card readers, the PRO reached 95 MB/s sequential read. Sequential write speed reached a maximum 83 MB/s.

We put the card to work in various digital cameras. In camera testing we found it to perform consistently among the top SD cards. It reached its highest write speeds in UHS-I cameras, where it averaged 67.4MB/s in the Nikon D330, 67.0 MB/s write speed in the Nikon D7100 and 65.6 MB/s in the Nikon D810. The Canon 7D Mark II reached 67.3 MB/s write speed. Its performance is nearly as good as much more expensive cards such as the SanDisk Extreme Pro 95MB/s UHS-I card.
