Version 7.0 of the SD standard finally raises the storage limit to above 2 TB, which was being rapidly approached by both full size SD cards (1 TB) and microSD cards (512 GB). It also adds an SD Express mode, which can raise speeds up to 985 MB/s, from a previous limit of 624 MB/s:
Soon you will be able to purchase new SD cards with the SD Version 7.0 specification. The new specification supports up to 985MB/s of throughput, which comes courtesy of PCIe and NVMe interfaces, and up to 128TB of capacity. That's quite the jump over the current 2TB limit.
985MB/s of throughput for a simple SD card may seem ludicrous, but higher-resolution video, VR, automotive use-cases, and IoT applications are steadily encroaching upon the performance limits of today's products.
[...] The specification has reserved space for new pins for future use, so it also provides room for forward progress (PDF). The specification also accommodates up to 1.8W of power consumption, which will help boost performance. The NVMe 1.3 protocol also brings several new features to SD cards, like Host Memory Buffer (HMB), which sets aside a small portion of system memory to boost performance, and Multi-Queue support, which improves performance during simultaneous file transfers.

It is, if you select the right senses for each word at least, and it's commonly used that way in the form of "pro and con lists" for instance. In this usage it derives from latin "pro et contra" meaning "for and against."

Oddly enough, I've just written a list of pros and cons without even thinking about it!

Con: I check this story when the comment count updates, and see more of this stupid grammar discussion continuing instead of memory card discussion.
