Gbps is a trendy unit used to measure the data transfer speeds of hardware devices.
Gbps has a complete form of “Gigabits per second” 1Gbps is 1,000 Megabits per second (Mbps), or 1,000,000,000 bits per second.
Only Mbps and Kbps were used to measure data transfer speeds for many years.
Using modern hardware interfaces, you can transfer data over one gigabit per second, making Gbps a fundamental unit of measurement.
For example, such interfaces include SATA 3 (6Gbps), USB 3.0 (5Gbps), and Thunderbolt (10Gbps). Additionally, Gigabit Ethernet can also transfer data up to 1Gbps.
By the way, storage capacity is typically measured in bytes, while data transfer speeds are usually measured in bits. Therefore Gbps is more commonly used in GBps.
