Top 10+ Characteristics of Secondary Storage Devices in Computers (2023)

Introduction to the characteristics of secondary storage devices

The computer is an electronic device that is used and used all over the world due to some amazing thingsProperties of secondary storage devicessuch as permanent storage, data access speed, reliability and efficiency.

There are two types of memory in the computer system

1. Primary memory or primary storage devices.
2. Secondary storage or secondary storage devices.

Explain and discuss what secondary storage devices are

Secondary storage is computer storage that can permanently store gigantic amounts of data and information.

The secondary storage devices are also referred to as"External Storage Devices" or "External Storage".

They are non-volatile memories because the data and information are not automatically erased even in the event of a power failure.

They can store data until someone intentionally erases or deletes it.

Unlike primary storage, secondary storage does not access data directly through the CPU.

The data and information stored in secondary computer memory is first loaded into RAM (Random Access Memory), called RAM"memory"and is later passed to the primary storage processor to read and access the information.

They are used for backups and to make copies of important information.

Different types of secondary storage devices

Secondary memory can be divided into two types.

1. Fixed Storage Devices.
2. removable storage devices.

Fixed Storage Devices

These devices are installed in the computer case, like computer hard drives and SSDs. They are attached to the computer with screws that are drilled into the computer case.

The fixed storage devices can be removed and replaced if damaged or damaged.

removable storage devices.

The removable disks can be easily disconnected from the computer. They are usually connected using a USB [Universal Serial Bus].

USB flash drives are one of the best examples of removable media.

1. Hard disk.
2. SSD [Solid State Drive].
3. USB-Sticks.
4. memory cards.
5. DVD's and CD's.

hard drives

Hard disk drives are also HDD, hard drive and disk. They are permanent storage devices that can store vast amounts of data and information.

They are non-volatile memory; therefore, no data is lost when the computer is turned off.

The capacity of each hard drive is measured in GB [giga bytes] and TB [tera bytes].

Famous HDD manufacturers are.

1. Seagate.
2. Samsung.
3. Western digital.

SSD [Solid State Drives].

Solid state drives are an advanced version of hard disk drives. They are more powerful and faster compared to standard computer hard drives.

The time required to access data and information is significantly less than with HDDs.

SSD can be used as internal and external hard drive.

Well-known SSD manufacturers are:

1. silicon power.
2. Seagate.
3. Samsung.

USB-Sticks:

USB flash drives are one of the most commonly used secondary storage devices. They are used and utilized extensively due to their exceptional features and properties.

They are compact and portable and can be carried from one place to another.

They are small and can be stored in a bag. They are lightweight and can hold and store vast amounts of data and information.

Well-known SSD manufacturers are:

1. HP [Hewlet-Packard].
2. Samsung.
3. Sandisk.

memory cards.

Memory cards are also known as "flash drives". These are small chips that are used in mobile phones. They can also be connected to computers, laptops and tablets.

Memory card reader is used and used to read data and information. The data is permanently stored on the memory card.

Famous manufacturer of memory cards.

1. Strontium-Nitro.
2. PS.
3. Sandisk.

DVD's and CD's.

DVD stands for Digital Versatile Disk and CD stands for Compact Disk. They are also widely used and used as secondary storage devices as they can store huge amounts of data.

Famous CD and DVD manufacturer.

1. Sony.
2. LG.
3. Moser Bear.
