Lexar has today announced that they’re expanding their memory card range with the new SD Express format. The SD Express 8.0 specification was first announced last May, expanding the initial SD Express 7.0 standard of 2018, promising speeds up to 4GB/sec. Lexar’s cards aren’t going to be quite that fast, though.

According to a press release, Lexar says the new SD Express cards will offer write speeds of up to 410MB/sec and read speeds of up to 824MB/sec. This falls quite shy of 4GB/sec, and slower than most CFexpress cards the market today. Of course, the speeds only matter if hardware actually requires it. And right now, there are no devices that use SD Express.

The SD association has announced SD Express 8.0 with transfer speeds up to 4GB/sec

Just when you think memory card speed limits are being hit, along comes the SD association to prove you wrong. This time, they’re announcing the SD Express 8.0 (SD8.0) specification which comes with transfer speeds of up to 4GB/sec (2GB/sec per lane up to two lanes). It’s built on the PCIe 4.0 standard and utilises NVM Express (NVMe) storage.

The first SD Express standard (SD7.0) was unveiled in 2018, offering transfer speeds of up to 985MB/sec, but it’s already been obsoleted by SD8.0. And the world hasn’t even adopted the SD6.0 UHS-III specification yet, either.

New SD card standard unveiled offering up to 985MB/sec transfer speeds and 128TB capacity

Just as we start to accept UHS-II into our lives, and before UHS-III is even a real thing, a new standard hits the streets. That’s right, folks, SD Express has now been announced, offering data transfer speeds of up to 985MB/sec. It also bumps up the maximum capacity from SDCX’s 2TB to the new SDUC’s 128TB.

SD Express uses PCIe and NVMe interfaces to deliver these faster transfer speeds. To read about how the SD Association talks about SD Express, it’s almost like they want or expect people to start using these as portable SSD replacements for general use.
