You need way more than 10 times the space friend. Try 60 times more space because 1 oz og gold is about 60 ounces of silver.
If silver skyrockets vis a vis gold I’ll happily endure the extra storage problems.

I stand corrected... I'm getting so many responses from this thread that I wasn't paying attention...
Silver has some things going for and against it from my understanding... first is that China might ban the export of rare metals which it has 98% (?) of the world's supply... and silver is known as an industrial metal (and a sort of substitute for rare metals too)... so if the economy is picking up... it is going to do better than gold.
However, if the economy is doing lousy... I would think silver would drag behind gold... but hey! It's your decision... :)
