The Difference Between CD, DVD, Blu-ray, and UHD in Video Games

When you play video games, you might notice that older games came on CDs, then later on DVDs, and now on Blu-ray or even Ultra HD (UHD) discs. But what’s the real difference between them?

CD (Compact Disc)

  • Used in: PlayStation 1, Sega Saturn, some early PC games.
  • Storage: About 700 MB (megabytes).
  • Details: CDs were the first big step away from cartridges. They could hold better music, videos, and bigger games compared to older systems.
  • Limitations: They didn’t have much space, so some bigger games had to use multiple CDs (like Final Fantasy VII on PS1, which needed 3 discs).

DVD (Digital Versatile Disc)

  • Used in: PlayStation 2, Xbox, Nintendo Wii.
  • Storage: About 4.7 GB (gigabytes) for single-layer, 8.5 GB for dual-layer DVDs.
  • Details: DVDs were a huge upgrade. Games could be much larger, with better graphics and longer stories. Also, the PS2 and Xbox could play regular movie DVDs, which made them popular home entertainment systems.
  • Limitations: As games grew bigger, even DVDs started feeling small by the late 2000s.

Blu-ray Disc

  • Used in: PlayStation 3, PlayStation 4, Xbox One.
  • Storage: About 25 GB for single-layer, 50 GB for dual-layer Blu-rays.
  • Details: Blu-ray was the next big leap. It had way more space for high-definition graphics, massive worlds, and long games.
    The PS3 was the first major console to fully use Blu-ray, and it helped games like The Last of Us and Uncharted look and feel amazing.
  • Bonus: Blu-rays also helped make the consoles into movie players for HD movies.

UHD Blu-ray (Ultra HD Blu-ray)

  • Used in: Xbox One S, Xbox One X, Xbox Series X (but not in standard PS4; only PS5 with disc drive).
  • Storage: About 66 GB for dual-layer, 100 GB for triple-layer UHD discs.
  • Details: UHD discs are even better versions of Blu-ray, designed for 4K video and huge games.
    Some of the biggest games today need this extra space for high-resolution textures, bigger game worlds, and faster loading times.
  • Note: Not all modern games actually need a UHD disc, it’s more about future-proofing for bigger games.

Each new disc type gave video games more space to grow better graphics, bigger worlds, better sound, and new experiences! Today, many games are even downloaded online, but physical discs still matter, especially for collectors and players who love having a real copy of their games.
