Samsung introduced its blazing fast EVO Plus UHS-I MicroSD cards last year, featuring capacities from 64GB to 256GB and write speeds approaching 90 megabytes per second. We were impressed with the 128GB sample we test drove, but Samsung has now expanded the lineup with a 512GB variant and sent one over to us for another look. The additional capacity is very welcome for videographers recording hours of footage. Granted, all that space is only useful if the card's write speeds are able to keep pace. The latest iteration advertises the same 100 MB/s read speeds and 90 MB/s write speeds as the rest of the lineup, but we want to see how it holds up in the real-world...
