News Lexar's latest SD 8.0 card is too fast for its own good — potentially DOA since no current devices exploit the card's 1,700 MB/s speeds

[Admin]

Lexar launched an SD 8.0 card with incredible read/ write speeds rivaling larger CFexpress 4.0 cards for cameras, but the company's hope for full backward compatibility is on hold as no devices can take advantage of these speeds, resulting in a performance downgrade to the UHS-I standard.

A while back I tried looking up these kinds of cards and only found 1 real review. The card got to 100C during the test. No wonder they're so hard to find, they're a safety hazard. review.

There's a reason why SD Express is dead in the water.

The SD standard was NEVER designed around PCIe.

Go back and finally implement UHS-III and stop wasting Time/Resources on trying to shove PCIe connectivity down a standard that existed long before PCIe was a glint in somebody's eye in the SD Association.

Trying to frankenstein in this spec is doing nobody any favors.

UHS-III is "Fast Enough" and focus on Storage Capacity & Cost Effectiveness.

Good luck getting even SDUC to anywhere near the number of devices as SDXC. I would like a 128 TB microSD some day.

"Hence, the whole purpose of buying a high-speed SD card is that it cannot be used effectively."

This doesn't mean whatever it is you think it does.

Edit: "While SD cards are convenient, the pros outweigh any benefit they could offer professionals."

Really? You mean the *cons* out weigh the benefit(s), if any exist.

It's a nightmare to use a RED CAMERA on a tropical climate.
IF this card hit 100c will be good at pole north.
keep your hands warm at the winter.

How’s it DOA? The cameras still work just fine as is. The benefit is copying it to the computer with a fast adapter. It will no longer take 30+ minutes to copy, it would just be seconds. Greatly speeding up production time.

Too fast for its own good, but also too expensive for its own good. Fast SD cards are ridiculously priced and a 512GB UHS II SD card can approach the price of a much faster 2TB NVME 2230 SSD on Amazon.

Speed actually is adequate atm and the never ending heat is an issue to both sensor heat dissipation and parts longevity, comeon it's a small memory card, not the one you put in your PC with massive heatsinks.

For shooting photos and videos I always prefer it last longer, don't burn my fingers and just get 1-2 sec more to write intot

SD Express 8.0 have not been finalized one month ago but May 19 2020. One month later JMicron announced the commercialization of the first card reader chip.
Manufacturers are building SD 7.1 card readers because they were no SD 8.0 card on the market.
Lexaar should have made this product for a client making a device needing those specifications. It's not hard to make a usb sd-card reader, so if the commercialization is not canceled we should see them come. Some laptops can also integrate this specification.

That's not how it works. The minumum speed under continuous use is what people actually care about. As long as that is better (IE nearer the maximum sustained speed of the device), then I don't care at all if they advertise by the theoretical maximum transfer speed.
Look at M.2 devices. You can get "PCIe 4.0" devices that range from slower than 3.0 devices. To only holds 4.0 speed for 100-200GB of transfer. And oddly you can get drives that are shocking value that will hold 2,000-3,000MB/s until full. Sometimes $50 cheaper than 'competitors' drives that perform much worse.
