By 1TB Micro SDCard Purchaser (21/03/2023)
Yes it does what it says but with my Samsung Galaxy Note 20 Ultra i set it to record everything in the Micro SD Card but when recording 8k videos at 24fps the phone automatically reverts back to the phones storage.
However the phone does still use the Micro SD Card for 4k videos at 60fps.
The cards read and write speeds are noticablly really high.
I do not regret my purchase as it is well priced and i don't really record 8k videos due to the file sizes anyway.
A wierd point to note the phone file size at the end of recording for the 8k at 24fps for 1 minute was around 560MB but the 4k at 60fps for 1 minute was around 500MB so not much difference, so maybe the phone done lots of background editing/optimising to reduce size which may have been resource hungry
