the higher fire protection the heavier the safe this may be a factor for you .also note the higher the price for 90min vs 30min,but check with our local fire department for advice i have heard some heavy safes on second floors colapsing and warping the seal of the safe if this occurs you belongings will be damaged by water or fire. and if u go with the heavy safe in the basement- flooding can be a issue and humidty is a high facter harder to control.
