Samsung has developed a new line of SD Express microSD cards that boast some seriously impressive specifications like 1TB capacity and 800 MB/s transfer speeds. That sounds great on the surface, but it isn't the whole story.
The SD Association announced a new standard for SD Express and microSD Express that adds new speed classes for the former and promises double the speeds of the latter. While great on paper, the updates do nothing to make the format desirable for camera makers.
If you’re a photographer, you’re likely familiar with memory cards. They’re what our photographs are stored on -- removable flash media that we insert into a slot (or slots) in our camera, take photos, and then (sometimes) remove and insert into a card reader or card slot on our computer.
Wise, a memory manufacturer based in Taiwan, has announced the world's first 512GB capacity v90 SDXC UHS-II memory card. Doubling the capacity of others on the market, the card promises a sustained write speed of at least 90 MB/s.
After reading my story on its $300 SD Express card, Ritz Gear reached out and insisted that I try it for myself. The company even included an SD Express card reader in an attempt, I assume, to show its value. After testing, I am at a loss: this is so much worse than I ever thought it could be.
Ritz Gear is currently offering a brand new SD Express memory card that it promises boasts up to 820 MB/s read and 500 MB/s write speeds for $300. In real-world use cases, it will never come close to these promises and it says so right on the box.
Adata has announced that it will be producing a line of SD Express memory cards, following Lexar which did the same earlier this year. It's unclear who these cards are for, however, as no manufacturer currently supports the spec.
Lexar has announced that it is actively developing on the thus far unused SD Express specification to create SD memory cards that use PCI Express (PCIe 4.0) and will more than triple the speeds of current UHS-II cards, but it's not clear who these cards will work for.
Earlier today, the President of the SD Association unveiled the new SD Express 8.0 specification. Built on the PCIe 4.0 standard using NVMe technology, SD 8.0 will "set a new standard for memory cards," with theoretical data transfer speeds of up to 4 gigaBYTES per second.
The SD Association has just announced the latest specifications for the widely used Secure Digital (SD) memory card format. The new Ultra Capacity (UC) designation will mean capacities of up to 128 terabytes and the "Express" designation will mean transfer speeds of up to 985 megabytes per second.
