It reminds me of how video game companies sometimes create whole virtual file systems in gigabyte+ blobs to deal with the limits of OS file systems. They're probably less useful in 2021 with SSDs becoming the norm. With hard drives, the thousands of files a game uses would end up in little fragments all over the platters and lead to horrible latency and head thrashing.

At least hard drives still have decent seek times. Load time optimization for consoles with optical drives was another league: a single seek across the disk could lead to waiting a second longer on the loading screen.

  Crash Bandicoot solved this problem by writing the level data in a streaming fashion, so that the CD-ROM would never have to seek while playing through a level. Of course, the CD-ROM only spins in one direction however. Crash Bandicoot programmers solved this issue by making it impossible to run backwards in the game. The game was basically one dimensional on purpose: you can only run forward, and never backwards, to optimize the CD-ROM bandwidth. Still, the game was groundbreaking, the gameplay and characters fresh. Its an incredible technical achievement, to the point where most people didn't even realize that running backwards was a technical hurdle they felt like not solving.
