The difference between hard disk and floppy disk

The difference between hard disk and floppy disk

First of all, hard disk and floppy disk are both magnetic disks.

1. The capacity of the hard disk is relatively large, which means that it can record more information, and it is usually installed in the chassis.

The capacity of the floppy disk is relatively small, and it is usually placed outside the chassis.

2. The hard disk is responsible for storing data in the chassis, while the floppy disk is used to transport data.

The hard disk has a large capacity and the floppy disk has a small capacity. This is the difference between the hard disk and the floppy disk. In addition, the access speed of the hard disk is much faster than that of the floppy disk.

Hard disk: It is one of the main storage media of the computer and consists of one or more aluminum or glass discs. The disc is covered with ferromagnetic material.

Hard drives include solid state drives (SSD drives, new hard drives), mechanical hard drives (HDD traditional hard drives), and hybrid hard drives (HHD, a new hard drive based on traditional mechanical hard drives). SSD uses flash memory particles for storage, HDD uses magnetic discs for storage, and hybrid hard disk (HHD: Hybrid Hard Disk) is a hard disk that integrates magnetic hard disk and flash memory. The vast majority of hard drives are fixed hard drives, permanently sealed and secured within the hard drive.

Floppy disk: It is the earliest removable media used in personal computers (PC). Reading and writing floppy disks is done through floppy disk drives. Floppy disk drives are designed to accept removable floppy disks, and currently the most commonly used ones are 3.5-inch floppy disks with a capacity of 1.44MB. Floppy disks have slow access speeds and small capacity, but they are removable and easy to carry. As a removable storage method, it is ideal for small files that need to be physically moved.
