  Wow. Pair this with a camera for unlimited buffer?

• MajGenRelativity - Tuesday, February 27, 2018 - link

  I'm not quite sure what that means

  It's common for SD cards to not be fast enough to keep up with the camera, limiting the rate at which you can take pictures. A card like this would let you take more pictures faster because the write speed to flash isn't a bottleneck.

  Ah that makes sense

  Unlimited buffer is simply overstating it, many camer makers put artificial limit to stop shutter mechanism from burning out. Also both Cfast and Xqd cards heat up while delivering tthroughputs of 400MBps or higher. Also depending on the camera they still can bottleneck the interface with large RAW files being written to card.

  A 50Mpx @ 14bit ≈ 90MB/frame

  How does that apply to video recording?

• Valantar - Wednesday, February 28, 2018 - link

  Video is pretty much always compressed, unless you're using >100 000$-range pro cameras - which mostly use SATA SSDs or external recorders with massive RAID arrays these days. RED specs their 5:1 redcode compressed 8kp24 output at roughly 270MB/s. They'd probably allow less compression if their storage system was faster, though, as they don't allow 8k60 below 12:1 compression (which they estimate at around the same bandwidth).

  Consider: "power concerns" - the camera might need a bigger battery, and a heavier heat sink (or fan?)

  I wouldn't want a camera that requires active cooling. Something like that would seem poorly designed to me.

• piroroadkill - Tuesday, February 27, 2018 - link

  Like this? https://petapixel.com/2016/10/11/cooled-nikon-d550...
  Heheh.... chilling the sensor has benefits.

• oRAirwolf - Tuesday, February 27, 2018 - link

  That is really cool (No pun intended)

• PeachNCream - Wednesday, February 28, 2018 - link

  That's cool, I agree (also no pun intended) but not the kind of camera I'd want to carry around for casual photography.

  Nice storage expansion for Surface Pro-like tablets... as long as new standard is accepted and built in future devices...

  Where does this leave the new QXD format that cameras like the Nikon D850 use?

• janolsen - Wednesday, February 28, 2018 - link

  Good, but the world's turning towards microSD. So fixing the size is one more step.

• Manch - Wednesday, February 28, 2018 - link

  Plenty of devices use regular SD cards still and just don't need the FF of microSD.

• edzieba - Wednesday, February 28, 2018 - link

  It's neat, but why even keep the SD card physical form-factor if you're completely changing the interface?

• andychow - Tuesday, March 6, 2018 - link

  Because they are the SD Association. They aren't going to promote a form factor which isn't in their sandbox.

• AnTech - Wednesday, February 28, 2018 - link

  Random read/write IOPS?

• Mday - Monday, March 5, 2018 - link

  Not when you consider electronic shutters, like what some of Sony's mirrorless line, and the Nikon D850 can do.
