To me this reeks of Western Digital style dishonesty[1][2]. I was wondering how long it would take for the new parent company to rub off on SanDisk and I guess I have my answer. My suggestion is to stay the hell away from anything Western Digital (and now SanDisk) if accurate specs are important to your use case.
What supplier would you recommend? WD and Sandisk have been my go-to for all things storage, but I prefer to pay a premium up to 20% for better quality.
My experience with WD spinning disks has been great. I've had two Sandisk SD cards fail which was a bummer but they both went into a read-only mode so I didn't lose any photos. I've switched to Samsung's high-endurance line for those.
