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

by 1 Comment

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.

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.

And in all that time, I have never written a blog about the do’s and don’ts of memory cards. Now that I have left Lexar and not on that side of the business any more, I feel that I can write this objective piece for you without any conflict of interest.

And if you are taking digital photos on a memory card (and you probably are), YOU WILL WANT TO READ THIS!

Transcend’s New SD Cards Are Meant to Go Through Hell and Back

by Leave a Comment

Transcend, a lesser-known manufacturer of storage devices, has recently unveiled a new lineup of Industrial strength SDHC and MicroSDHC cards capable of withstanding extreme temperatures.

They’re called the Wide Temperature lineup and as their name suggests, these SDHC and MicroSD cards are meant to be pushed to the limits. How far? Transcend claims these MicroSD cards are capable of temperatures from –40ºC to 85ºC (–40ºF to 185ºF), more than enough to get that ridiculous GoPro footage.[Read More…]
