The thing regarding the limitation on invention salvage is that it applies to base items, one of the reasons lighting flickers every time you remove/add items to storage, it's updating the base items listing. And base items also have a limitation, or at least it used to, something like 20k items as the more items that have to be loaded every time you enter your base the longer the load times and bigger impact it has on your system.
I still keep White/Yellow invention salvage in storage, but I do limit the quantity to 5-10 per piece. I recommend going through your storage and cleaning regularly, drops stacks in the AH on the cheap.
