I use Macbook pro with USB-C, so i ready for it..Sony and SanDisk already has one, expect to see more soon from the usual names. Just be aware they could come with USB-C or Thunderbolt interfaces , so if your PC does not have one, you may need an adapter or a new exapnsion card for a direct connection.
I'm curious to see if someone will offer a card reader directly attached to a PCIe bus....
You‘ll ideally want a TB3 one for max speed. Though USB should be fast enough for the current gen CFE cards. The current Scandisk one isonly USB. Also XQD readers may get firmware updates to supp CFE so worth checking out in the manufacture, worth checking out.
https://www.amazon.com/Blackjet-TX-1CXQ-CFexpress-Reader-Thunderbolt/dp/B07YBLQ3HJ for you consideration. It’ll let you dump the card at full speed, bottlenecked only by your computer’s storage.
I can confirm this is also happening with ProGrade card reader on MAC OS.Like many others i received my 1D X III with a 64 GB SanDisk CFexpress card and a voucher for the SanDisk card reader.
Meanwhile i purchased two different card readers from other brands:
In principle both readers are working fine on two different Windows 10 machines with a USB 3.1 Type A to USB-C cable.
- Delock 91749
- Wise WA-CX01
BUT: even in idle operation (leave card in the reader, no reading or writing) the card is getting VERY HOT!
That worries me because:
I measured a constant 400 mA current draw, that is 2 Watts electric power !!!
- this unnecessarily drains my notebook's battery
- i'm not shure if it's harmless for the memory card in the long run
I never saw this with any "antiquated" CompacFlash, CFast or SD card, they consume a maximum of about 50 mA during read/write and power down to less than 1 mA in idle state!
The CFexpress card seems to stay cool in the camera and i doubt it consumes that much energy as then the camera's battery would never have that much runtime.
Is anyone else experiencing the same effect?
Could it be Windows-related (can't test with MacOS)?
What if you use a "native" USB-C port?
Is it a problem of the card readers (but as said i tested two different manufacurers) or the card?
What about those of you who have a original SanDisk card reader?
