Yesterday at Walmart I remembered that I should look for a “fireproof safe” or something that can protect my media content in my own apartment. They cost about 100-150$.
Then I came across this great post on the alt.firefighters google newsgroup explaining the difference between fireproof safes and “media vaults” which is really what I need. It costs about $300-400, but it saves me the trouble of having to store something offsite. He refers to the UL Standards Page. Great stuff!
