Question

Modern computers often come with hard disks and solid-state disks (SSD) but no optical disk drives.
Explain why computers often have both of these types of storage rather than just having a hard disk or just having an SSD.

Answer 1

Answer:

SSD makes the computer fast and the time taken to process the data is reduced..

While hard disk provides more space.

so both SSD and HD are are now-a-days used in modern computers

Answer 2

The traditional spinning hard drive has been a standard for many generations of personal computers. Constantly improving technology has enabled hard drive makers to pack more storage capacity than ever, at a cost per gigabyte that still makes hard drives the best bang for the buck.

As sophisticated as they’ve become, hard drives have been around since 1956. The ones back then were two feet across and could store only a few megabytes of information, but technology has improved to the point where you can cram 10 terabytes into something about the same size as a kitchen sponge.
