Computer storage disks and RAM are manufactured in binary units (power of 2) Bytes, KiB, MiB, GiB…
The binary prefix convention (IEC 60027-2) allows common numbers such as 2048 bytes to display as round numbers, so 2 KiB

Power of 10 numbers are also calculated above (KB, MB, GB…) these are used by Apple and some hard drive manufacturers.

Many documents still incorrectly use the old-style : KB,MB,GB… prefixes to refer to a power of 2 value.
The 'B' character for Bytes is case sensitive and easily confused with 'b' for bits: 1 Kb=1000 bits or 125 Bytes (1 Byte = 8 bits)
Bytes are used to measure disc/file sizes. bits are used to measure network or download speeds.

Convert between Binary, Decimal, Hex and Base 36

Decimal: Binary: Hex: Base 36

Typical throughputs:
Hard disk = 30 MiB per second. (x8 = 240 Mb/Sec)
Gigabit Ethernet = 125 MiB per second. (x8 = 1,000 Mb/Sec)
Solid State Disc (SATA) = 250 MiB per second. (x8 = 2,000 Mb/Sec)
Solid State Disc (NVMe PCIe 4.0) = 2 GiB per lane per second. (x8 = 16 Gb/Sec)
Fibre Channel = 2,550 MiB per second. (x8 = 20,400 Mb/Sec)
