The SD Association, the group that sets the standards for memory cards, announced a new SD 8.0 specification for SD Express memory cards today that will allow the cards to transfer data at a rate of nearly four gigabytes per second, in large part thanks to utilizing PCIe 4.0 and NVMe interfaces commonly found in solid-state drives. That faster transfer rate could be useful as new technologies, like 8K video, create ever-larger files, which in turn require faster throughput if you want to transfer data in a timely manner.
Specifically, the 8.0 specification allows for transfer speeds of up to 3,938 megabytes per second, according to an SD Association white paper. That’s a significant jump from the maximum transfer speeds of 985 megabytes...
