Will Hot Weather Damage My Flash Drive?

We all know that many electronic items and accessories are sensitive to heat. A reader is worried about a recent order of flash drives.  “My order of flash drives were delivered to my mailbox on a day when the temperature was over 100 degrees.  I am not sure of the time of the delivery, but based on my observations for when the mail has been delivered in the past, the package was exposed to high heat for 9 or 10 hours.I want to know if this has damaged the flash drives.”


Since flash drives go into slots in PCs, they are designed to withstand some fairly high temperatures. These storage devices operate optimally between 32 and 160 degrees Fahrenheit.  I checked the weather for your town and the high on the day your package was delivered was 97 degrees. So even 10 hours in your mailbox shouldn’t be a problem.

If you’re concerned, try doing some test saves on the drives to make sure it’s working properly.
