Question:

What are the file sizes of the Collection 1 Level-1 data products and how do they compare to Pre-Collection files?

Due to additional files in the Landsat Collection 1 Level-1 data products, the compressed file you download will increase in size: 

(Compressed file size/Uncompressed file size)

Landsat 7 ETM+ Pre-Collection: 255 MB / 650 MB
  Collection 1: 235 MB / 785 MB
     
Landsat 4-5 TM Pre-Collection: 140 MB / 380 MB
