Most of the time recordings would be stuff like blueprints,plans, photosof targets, important conversations, spied on conversations etc... which means you have a general idea of where you have to look if you need to recall something and most likely named them something to make them easily identifable, which voids most of the "common" memory test that a runner would require(and you said yourself, common runner most likely won't need it, and this is one of the reasons for it).
I fully agree that it doesn't always help you, especially if you never thought it would be important and never bothered to record it, just like most qualities simply give you bonus dice and not just instant: you remember this.
But even then a memory test for "in which conversation did i hear someone mention this name x so i can replay the conversation and remember it" is a lot easier then a plain "what was x name again?".
In conclusion everyone should just record everything... because that way the corps who go through our stuff have no chance of finding anything usefull in all the trash they're getting ....i think i might have gone a little off topic here
