Answer 1

EDIT: Revised first 2 paragraphs to emphasize being on the safe side.

@Donald... Based on the information below, I think you should be okay with that temperature for brief amount of time.

However, like @Harsh pointed out, 80 ºC is on the more extreme side of the range. So, extended exposure could be a problem. At least that's how I would approach it. 😉

Ultimately, it might depend on your specific SD Card model and brand. I suspect most are targeting the same temperature range.

For Example:
-----------------------
SanDisk SD, SDHC, microSD and microSDHC memory cards are capable of withstanding operating temperatures from -13ºF to 185ºF (-25ºC to 85 ºC).

That said, this temperature range may not be suitable for older Raspberry Pi models, as indicated by the Raspberry Pi FAQ:

-----------------------
8. WHAT IS ITS OPERATING TEMPERATURE?
The Raspberry Pi is built from commercial chips which are qualified to different temperature ranges; the LAN9514 (LAN9512 on older models with 2 USB ports) is specified by the manufacturers as being qualified from 0°C to 70°C, while the SoC is qualified from -40°C to 85°C. You may well find that the board will work outside those temperatures, but we’re not qualifying the board itself to these extremes.

Answer 2

lol you're funny David!! :) !😂

Answer 3

David Carrol knows what he is talking about do whatever he says:)!!!:)

Answer 4

SD cards are limited to 85℃, so because of that I wouldn't recommend using it in such conditions.

Answer 5

im not sure but sd storage works pretty like ssds,
it should be fin till 110°C , but not good for the durability

Answer 6

ohh yeah im taking no responsebility

Answer 7

I only pretend to know what I'm talking about. Mostly, I just fake it till I make it. 😉
