Storing drives in a fire/water-proof safe


Recommended Posts

Simple answer, don't do it.

One of my friends mentioned that he was looking at fire/water-proof safes for drive storage. This is the model he was considering:



The specs state:

'The safe has been tested by an independent testing lab and verified to protect electronic media including memory sticks; CD’s; DVD’s and external hard drives. In addition; the safe will protect documents; electronics; and other valuables.'

'The 1.3 cu. ft. Combination Waterproof Fire Resistant Safe is UL classified for one hour to withstand an external temperature of 1700° F while maintaining an internal temperature of less than 350° F.'


The issue I have with this is, 350F is well past the non-operating temp of disk drives. Most are rated up to 70C/158F:


SSD and USB drives are generally rated up to 85C:



I would like to see someone test a fire safe inside of a fire/water proof safe. Something like this inside of the safe listed above:


I would assume if the bigger safe can keep the temp down to 350F, then the small safe should be able to keep the temp below 150F.

I gave up on that idea last year after some research.  I wanted one I could store small valuables in, as well as drives.  It also had to be something that couldn't be easily stolen (i.e. bolted to a concrete floor or wall from the inside).


It got way too expensive very quickly, and I abandoned the concept in favor of bank-deposit-box for the valuables and cloud storage for the data.

I think the biggest problem for HDDs is the plastic parts in them. Most of these parts are thermoplastics, and they don't take kindly to higher temps.

Can the cloud catch on fire?


I thought it was all water vapour (vapor for those in USA) and would thus be fireproof.




Some of the newer visitors might like to see Dave's video testing the ioSafe 5 years ago.
