About Gibibytes

A gibibyte (GiB) = 2³⁰ = 1,073,741,824 bytes (IEC 80000-13). The source of the 'storage discrepancy': a '500 GB' drive contains 500×10⁹ bytes ≈ 465.66 GiB as shown by Windows. RAM is manufactured in exact powers of 2: 4/8/16/32/64 GiB. GPU VRAM: RTX 4090 = 24 GiB; H100 = 80 GiB; MI300X = 192 GiB HBM3. Kubernetes memory limits use Gi suffixes. 1 GiB = 2³⁰ bytes = 1,024 MiB.

About Megabytes

A megabyte (MB) = 1,000,000 bytes (SI). Used by all storage manufacturers and by macOS (since 10.6), iOS, and Android. Typical file sizes: JPEG photo (50 MP) = 8-20 MB; 3-min MP3 at 128 kbit/s ≈ 2.9 MB; Android productivity APK 10-150 MB; full-frame RAW photo (Sony A7R V, 61 MP) 60-120 MB. H.264/H.265 achieves 30-100× compression vs. raw video. 1 MB = 1,000,000 bytes = 1,000 KB.
