About both units

From

Terabyte

TB

The terabyte equals 10¹² bytes (SI) or 2⁴⁰ bytes (binary, TiB). Used for large drives, NAS units, and big-data contexts. A 1 TB drive holds around 250,000 photos or 500 hours of HD video.

Real-world: Desktop HDD: 1–20 TB. Typical NAS: 4–48 TB. Cloud-storage plans: often 1–2 TB.

Petabyte

PB

The petabyte equals 10¹⁵ bytes. Used for datacenter storage, scientific datasets and video archives. 1 PB could hold the text of 500 billion pages.

Real-world: Netflix total catalog: many PB. CERN LHC data: 100+ PB/year. YouTube uploads: EB scale now.

Tips & common mistakes

Quick tips

  • 1 TB = 1000 GB (SI). 1 TiB = 1024 GiB.
  • TB drives formatted show less in OS (binary vs SI).
  • Archival/backup workflows typically measured in TB.

Avoid these

  • Expecting a 1 TB drive to hold 1 TiB — actually 931 GiB formatted.
  • Buying a TB drive for backup without considering RAID overhead.
  • Confusing TB with Tb (terabit, 1/8).
