In November, ProGrade Digital announced the largest SD cards to date in their Gold V60 UHS-II lineup. With the data storage needs of video shooters today, such large cards are in high demand – especially at reasonable prices. So, we took the new $199 ProGrade Gold 512GB V60 UHS-II card and put it through speed tests to compare it with ProGrade’s $499 Cobalt 512GB V90 UHS-II SD card.
While there is a little difference in the maximum hypothetical read speed of the card (250MB/sec vs 300MB/sec), they offer minimum sustained write speeds of 60MB/sec and 90MB/sec, respectively. For many of us, this may not matter. 60MB/sec equates to 480Mbps – more than plenty for most cameras on the market – but is it worth getting the V90 card (720Mbps) if you don’t really need it? Let’s find out.
