just remember that those numbers are what they are capable of doing under specific test conditions. the other end of the equation is the device you are using them in. and that will cause considerable variations in real world use.
Sandisk pro cards have "lifetime" warranties. you must keep your receipts for proof of purchase.
Sony Tough i believe are 5 years same requirement on POP
To simplify... those speeds are "up-to" speed ratings in a controlled environment and may not reflect real world use.
If you're into high speed (burst photography) the Sony's higher write speeds may be beneficial to you; other than that, I doubt you'll notice any difference between the two.
I'm a SanDisk Extreme Pro fan, but with my Nikon D850, I'm using a Sony XQD as the primary card, with a SanDisk Extreme Pro (UHS-1) as my backup card.
Really not rocket science as any name brand SD card will work. It's just a matter of what you want to pay for what speed and size. Only you know that and know what your requirements are.
you could be correct or there just wasn't enough access to readers and or cards. it is just recently that they are showing up;
1- properly working yes, talking about you SanDisk
2- in greater variety
i have to readers. one dual XQD/CFexB and one dedicated CFexB. the dual is the Sony and in use daily and works spot on w/XQD. still standing by on CFexB till the infamous FW update shows up as promised by the end of the year

we can only stand by.
Could you tell me more about problem with CFExpB reader ? I have this dual XQD/CFExpB and did not notice issues yet
i have no problem with the reader.
the Sony is in use but only with XQD cards at the moment because thats all i have. it functions perfect for XQD so far.
the Delkin reader (my portable) is strictly CFexpB
i have no reason to run and jump on CFexpB as i have 9 cards varying from 25-120GB volumes and 3 cameras that use XQD 2 of them are waiting for the the fabled FW update that allows the use of CFexpB in them too. and from there on replacements will be CFepB if they at minimum deliver the same performance as their current XQD cards do.
SanDisk had issues with their first round of cards and their reader was challenged. it seems that even though they were one of the original "developers" of CFx they failed to read and use their own specs in manufacturing. from what i understand the reader is still not the greatest but the cards were fixed and have a new P/N. i also thought the Delkin was better for travel. its built to take relative abuse.
Yes I can confirm > New Sandisk CFExpress Card SDCFE-128G-ANCNN works very good ( IN does not)
Sony XQD/CfExpress reader read this Sandisk CFExp B as good as Sony XQD cards. No problem there
