My drive says 1 TB but shows 930 GB. Why?

Marketing uses decimal (1 TB = 1,000 GB). Operating system uses binary (930 GiB ≈ 1,000 GB). Also: OS reserves ~70 GB.

How many hours of 4K video fit on 2 TB?

4K video: ~100-200 GB per hour. 2 TB = 2,000 GB. So roughly 10-20 hours of 4K content.

What does 'TiB' mean vs 'TB'?

TiB = tebibyte (binary, 1,024 GiB). TB = terabyte (decimal, 1,000 GB). Often confused; tech specs vary.

My data center inventory lists drives in TB, but my monitoring software reports in GB. I have 100 drives of 2 TB each—how many GB is that total?

Each 2 TB = 2,000 GB. For 100 drives: 100 × 2,000 GB = 200,000 GB total.
