In October 2023 I wrote an article here with the headline: Dead and buried already? The latest SD card standard is fast but flawed. This was in reference to a then-new update to the little-known SD Express memory card format, which claimed microSD Express version 9.1 cards could be capable of an impressive 1969MB/s maximum transfer speed. All well and good, but with no devices that actually supported SD Express cards at the time, and with an equal shortage of the cards themselves, there seemed little practical point to the new format, regardless of its advertised high speed.
And for the past 18 months that news story has remained valid: SD Express cards still haven't materialised, and consequently there are still no mainstream devices that support the format.
