10+ Differences Between Fixed And Removable Disk Drives


The computer system consists of fixed and removable disk drives, also called “Internal and External Disk Drives.” These devices are essential to a computer system for better performance and functionality. These disk devices are used for storing, sharing, and transferring data from one location to another. Fixed drives are fitted inside the system called “Internal Disk Drives,” whereas the removable disk drives are considered “External disk drives.” There are significant differences between fixed and removable disk drives and fixed vs removable disk drives that have been discussed in the article. Let’s get started…

What is Fixed Disk Drive in Computer System?

A fixed disk is also a hard disk drive or HDD. They are a type of non-volatile memory as the data and information are not lost when there is no power or electricity.

The data can be accessed anytime whenever requested or demanded by the user.

The fixed disk is also referred to hard disk drives, fixed storage, and fixed media. The hard disk or fixed disks are permanently mounted inside the computer cabinet. To change or Upgrade complete system has to be disassembled.

The platter present inside the hard disk is called the "Fixed Disk."

They are compact and can store or hold incredible data, therefore, gained immense popularity and became a leader in their industry.

The data is secure, and their performance is highly rated.

Types of Fixed Disk

  • Serial ATA (SATA),
  • Parallel Advanced Technology Attachment (PATA),
  • Solid State Drives (SSD),
  • Small Computer System Interface (SCSI).

Uses of Fixed Disk

  • They are used in storing massive amounts of data and information
  • The data and information can be accessed and retrieved whenever needed or required.
  • Fixed disks are also used in software development, Application development, website designing, and development.
  • Data and Information Sharing.
  • Gaming
  • Plays a vital role in networking for sharing data.

What are Removable Disk Drives?

The removable disk drives are external drives like USB Hard Disk Drives, Pen drives, and thumb drives. They can be used as portable devices and attached to another computer, laptop, or device.

They are far more efficient and reliable than their counterparts.

They are also used for additional backup storage. The removable disk is often called "External Disk Drives."

Examples of Removable Disk Drives

  • USB Hard Disk Drives.
  • USB CD / DVD.
  • Pen Drives.
  • Memory Cards.

What are Non-Removable Disks?

Non Removable disk drives are a computer system’s essential components and hardware and are used and utilized for data and information storage.

A removable disk can also be named a removable drive, removable storage, or removable media.

These non-removable disk drives are fitted or installed inside the computer case or laptop, which is not easy to remove or upgrade. 

To remove, change or upgrade these devices user needs to disassemble the machine completely, computer or laptop.

Non Removable disks are non-volatile and do not lose data and information when there is power loss.

Some Examples of Non-Removable Disk are
  • Hard Disk Drives
  • DVD RW
  • CD RW

The performance and speed of non-removable are far better than removable disks. Standard HDD [SATA | PATA] are inexpensive compared to SSDs [Solid State Device].

4 Types of Non-Removable Disks

  • Hard Disk Drives.
  • Floppy Disks
  • CD [Compact Disk]
  • DVD [Digital Versatile Disk]

4 Types of Removable Disk Drives

  • USB Hard Disk Drives.
  • USB CD / DVD.
  • Pen Drives.
  • Memory Cards.
  • Tape Drive cartridges.
  • USB Thumb Drives
  • SD Cards
