Fastest Item Stack Transportation

https://youtu.be/AGW0IQIWZlU

I have created a very fast item transport system with slime blocks, sticky pistons, and packed ice. In the video, I am comparing my mechanism to the dropper system, which is the fastest single item transporter. Here are the pros and cons to both mechanisms:

My creation:

Pros:

• Very efficient and quick to transport stacks of items.
  
• Almost no noise.
  
• Faster than all transportation systems excluding the dropper system.
  

Cons:

• Only a tad bit slower than the dropper system in single item transport.
  
• Resource intensive (LOTS of slime).
  

Dropper System:

Pros:

• Fastest single item transport in the game.
  
• Easy to build and does not require many resources.
  

Cons:

• EXTREME amounts of noise.
  
• May lag world.
  
• Cannot transport stacks of items as fast as my creation.
  

All in all, I would suggest building my creation for item stack transport and for less noise. I have not created or uploaded a world for people to study the mechanism, but I will be making a tutorial later.
