I'd like to suggest the following mod:
Applied Energistics
http://www.minecraftforum.net/topic/1625015-146-applied-energistics-rv-1-a/
It's a really neat add-on to the tech-mods (like buildcraft). For now, it adds a 'storage solution' in the form of transportation of energy.
I feel like this post really doesn't do this mod justice...
Applied Energistics is a mod with a simple yet powerful idea, and that is the transformation of matter into pure data-energy which can then be transported near-instantaneously through wires. In its current state, it is primarily a (rather expensive) cloud storage solution with considerable potential for automation as well. The network consumes its own form of energy per tick (which can be generated by either MJ or EU) and while in this 'on' state it will accept items either manually from an access terminal or automatically via an ME Interface or an ME Import Bus. Items are then sent to what form of storage is within the system, which can be either physical storage such as chests or barrels if you attach an ME Storage Bus to it, or the pure Mass Energy data can be stored on special items called Storage Cells.
Storage Cells are items which are essentially hard drives for items, each has a specific amount of 'bytes' which can be stored upon it, and this number cannot be exceeded. Additionally, it is more efficient to store only one or two items within a single cell, as every additional type of item will cost additional bytes.
These storage cells can then be placed within either ME chests, which can store a single cell and are useful if all you want to do is store items more efficiently, or ME Drives, which do not have the same interface as the chest, but allows you to store several cells within itself.
This mod also adds a very interesting early-game method of ore doubling, called the Quartz Grind stone. This requires nothing more then stone, wood, and 3 Quartz dust (the only world gen added by this mod) and allows the player to use their character's own manpower to grind ores into double the dust, but slowly. Quartz can also be used to make iron-equivalent tools, and it also adds the ability to grind 2 wheat into 1 flour, which can be baked for bread.
This is, of course, not everything this mod adds, and I encourage you to go check out its wiki page (
http://ae-mod.info/) and either peruse around or watch one of the video tutorials. Personally, I would say the potential to reduce lag reduction of servers alone, through the elimination of massive amounts of tubing and sorting systems and the like, is more then enough reason to implement another world-gen ore into the packs. Especially future packs, such as the Ultimate Pack.
