Arcade game machines rely on various types of storage media to store and run games efficiently. The most common types include:

1. ROM Cartridges – Early arcade games often used read-only memory (ROM) cartridges, which were durable and easy to swap for different games.

2. Hard Drives (HDDs) – Modern arcade cabinets sometimes use hard drives for larger storage capacity, allowing for more complex games and updates.

3. Solid-State Drives (SSDs) – Faster and more reliable than HDDs, SSDs are increasingly popular in newer arcade systems for quick loading times.

4. Flash Memory – Many arcade machines use flash-based storage for its speed, durability, and low power consumption.

5. Optical Discs (CD/DVD) – Some arcade systems, particularly redemption or hybrid machines, use optical discs for game distribution.

Each storage type has its advantages, depending on the arcade machine's age and design. Understanding these options helps in maintaining and upgrading classic and modern arcade systems.
