Greetings! I’m having a heck of a time finding information on this, and was referred here to seek technical advice from those who know!

I’m purchasing 2 Galaxy S20+ and intend to get an SD card for use as expandable internal storage. Doing research on SD speed classes ( Speed Class | SD Association ) It looks like the best fit for the S20+ would be something with a V60 rating, but upon review of the “specs” it states “sequential read/write speeds up to 3,500/3,300 MB/s” which of course blows any sd class out of the water. I know sequential speeds are like highway MPG in cars, but still.

Does anyone know how much of an impact getting a V30 or V90 would be on write speeds when recording video at 4k? Or just in general? Are there any hard numbers on lag in milliseconds/seconds? Ive read that higher frame rates dont save to sd cards, but what about when they are formatted to be internal storage?

Does anyone have any data on bottlenecking when recording at high resolutions in terms of formatted internal storage cards?

Thank you in advance for any assistance or resources that might be shared!

I only have a Class-10 but I've never had any issues with 4K video.

Have you had any luck recording at 8k? also is your SD card formatted to be internal storage, or is it still a removable/interchangeable drive?

Mine automatically records 8k to internal storage. That may be because the SD card is still removable. I honestly really don't use 8k though because of the low frame rate.

The Galaxy S21 and S22 (any model) do not support expandable storage. They do not even have microSD slots on the devices.

It depends on if you're transferring data from your phone to a computer or another mobile device.
If its to a windows computer, you just need to connect the phone and computer via USB and go to "This Computer" and select the phone from the connected devices, then navigate to the data you want transferred and move it to the PC.

If you're moving from your Samsung phone to another phone the "Smart Switch" app is the way to go. It's Samsung's automatic transfer tool. you can do it wirelessly over a wi-fi connection, or via usb cable.
