Depends on the size, but today they are usually measured in Gigabytes, although older devices might be measured in Megabytes.
These are secondary storage devices such as the hard disk
Auxiliary storage devices are used to provide additional, portable storage, as opposed to hard drives which are fixed inside the computer and serve as primary storage devices. ------------------------------------------------------------------------------------------------------------------ Auxiliary storage is a term used in mainframe computing and refers to the medium on which paging datasets reside.
Secondary storage is?æthe devices for permanent storage and it is not affected if the computer is turned on or not. Secondary storage is?æmostly known as auxiliary storage or external hardware.
The capacity of storage devices is measured in megabytes, gigabytes, terabytes, etc.
An auxiliary storage device refers to any type of storage device--except for the internal memory, usually referred to as RAM (Random Access Memory)--that is used to save information. From the moment you start typing a letter in Microsoft Word, for example, and until you click on "Save", your entire work is stored in RAM. However, once you power off your machine that work is completely erased, unless you had saved a copy on an auxiliary storage device, like an internal or an external hard disk drive, optical drives for CDs or DVDs, or a USB flash drive.

Auxiliary storage, also known as secondary storage, refers to external devices used to store data that cannot be directly accessed by the CPU. Examples include hard drives, solid state drives, USB flash drives, and optical discs. It provides additional storage capacity to complement the primary storage (RAM) in a computer system.

Storage is measured in a hierarchy of bytes.

there is no difference!
Some devices do not contain storage devices, or do not have enough storage space needed by a particular user. Extra storage devices such as an external hard drive can be utilized.
