How to store large amounts of bigger bricks?
It depends a great deal on your play style and just how much Lego you have, and on what other skills and equipment you have. Using official Lego containers is the most expensive and least flexible option, as they are not really in the storage business. The Technic Briefcase is a good start if you have Technic, but those get pricey if you want more than a couple.


The basic idea is there though - you want a lot of compartments in a few different sizes. Many people buy plastic storage systems, either tackle boxes or drawers (or both), in quantities ranging from "a couple" to "the entire wall of my playroom". Drawers have the advantage that they stack vertically very well, so you can fit a lot of compartments in a small-ish space, and you can get systems that lock together or attach to the wall. Tackle boxes are more portable but harder to get things out of, and organising the boxes can get ugly when you get a lot of them. But I prefer tackle boxes because they give me a wider variety of parts per area of desk, and they're portable.

Since I'm kinda crafty in other ways, I actually built my own tackle box like trays out of wood. That has the advantage that I can customise them exactly how I want them, but obviously I needed a table saw and other tools to build them. Photos here
