Areal Density: HDD Capacity Explained
WEB10 oct. 2023 · Areal density is typically expressed in gigabits per square inch (Gb/in 2), or sometimes in terabits per square inch (Tb/in 2) for higher-capacity hard drives. What is the formula for areal density? Areal density is calculated by multiplying the number of bits per inch (BPI) by the number of tracks per inch (TPI).
