Difference between cards with the same specifications

Memory Cards SD | microSD | CFast | CFexpress | CompactFlash

What’s the difference between cards with the same specifications? Only packaging? Or marketing strategy?

Example 1.1

The 64 GB version are both 90/40 MB/s and are visually indistiguishable too but numbers are different.

Example 2

Ultra and Ultra Plus (128 GB version) are both “Up to 80MB/s read speed; write speed lower”. Maybe difference is in the not officially declared writing speed? Or Ultra Plus is obsolete and will be updated with faster speed in the near future?

Hello, 

as far as i know the sandisk website takes some time to get updated to the latest version of the cards along with the specs and speeds. So it can be that they list some olrder model of the cards an it seems that the ultra plus with ultra have the same speed but still are different cards

just my opinion

Thanks!

This could apply to the second example (SD).

Regarding the first example (microSD) it seems me it’s only a question of marketing. I’d like an official statement about this. This is quite confusing and annoying for customer like me interested in buying these cards. What’s the real difference if any?

Hello, 

since this is a forum and you wish to have an official statement, then i suggest contacting the support directly:

Asked last, waiting for reply.

Received now a clear reply.

"There is no difference, this was a marketing decision.

The cards will have same speeds and have same performance."

Anyway I’d eliminate this marketing difference at all. It doesn’t help customers.

Thanks.
