What is a terabyte?
The terabyte is one trillion bytes, or 1,000 GB. Hard drives, SSDs and cloud backups are sold in TB. A 1 TB drive holds about 250,000 photos of 4 MB.
What is a tebibyte?
The tebibyte is 2⁴⁰ bytes, about 1.0995 terabytes. The gap between binary and decimal grows with each prefix and reaches almost 10% at this scale, which is why a 4 TB drive shows about 3.64 TB in Windows.
