Question 1

Is it mlc or tlc?

Accepted Answer

I can't find anything in writing from SanDisk to confirm this but based on the warranty (10 years) and write speeds (40MBps+) there is no way this is TLC. TLC is usually less than 15MBps and no one offers a warranty that long on TLC. It has got to be MLC.

I have been using the card in our 4k dashcam for almost a month now with no hiccups. Writes 2 video streams, 4k front and 1080p rear with no problems.

Question 2

Other than the warranty, why not buy the cheaper Pro Endurance?

Accepted Answer

The Pro version wears out sooner than the Max. If I am reading the stats correctly, the Pro 128 GB has about 1/4 less total hours of recording in its lifetime than the Max 128 GB version. It also has a lower number in that U symbol (1 versus 3), which seems to pertain to its record-write speed. The Pro has a transfer/copy-write speed of 30 MB/s, versus the Max's 40 MB/s. The Max might be more physically resilient.

The plain High Endurance one is as fast as the Max, and less expensive than the Max. However, it is more expensive than the Pro, and has a grossly inferior lifespan than the other two. I don't see any reason to bother with it.

The Pro will suffice for most who are only needing it for like a spy cam or an intermittently recording (it records when something triggers it, not constantly) surveillance system. The Max is more suited for those who need 256 GB cards and have 24/7 systems, and/or they must have greater write speeds (all three are stated to have 100 MB/s read speeds). Or, as you said, they need a longer warranty.

Question 3

could these be use in phones note9 s10 will it be better than extreme pro?

Accepted Answer

I don't think this will be better than extreme pro, this micro sd is for durability, mean that it will be able to stand for frequently read write, while extreme pro is optimized for speed so it should work better for normal user. Endurance card is better for security camera or drone.

Question 4

Is there a stated operating temperature range?

Accepted Answer

SanDisk Max Endurance devices can work an extreme temperature range between -25°C and 85°C (-13°F to 185°F)
