title: Why does my Hanye storage device (USB drive/SSD/memory card) show less capacity than advertised? category: Performance & Specifications

sort: 1

• This is normal. There are differences in how storage capacity is calculated:
  • Manufacturers typically calculate 1GB = 1,000,000,000 bytes (10^9 bytes).
  • Operating systems (like Windows) typically calculate 1GB = 1,073,741,824 bytes (2^30 bytes).
• Additionally, some storage space is used for firmware, formatting, and file system management (like over-provisioning, wear leveling), which slightly reduces the available space.
