Which of the following storage devices can store the maximum amount of data?

Correct option is D

A Hard disk has the highest data storage capacity compared to the other options. Hard disks are commonly used in personal computers and servers to store large amounts of data, ranging from gigabytes (GB) to multiple terabytes (TB). They use magnetic storage technology to store data non-volatilely, ensuring that the data remains intact even when the device is powered off.
Important Key Points:
1. Hard disks offer significantly higher storage capacities, often exceeding 16 TB (approximately), making them ideal for storing operating systems, software, and large files.
2. They are reliable and can support both random and sequential data access.
3. Hard disks are generally used for internal storage in computers and external storage for backups.
Knowledge Booster:
· Floppy disks have very limited storage capacity, usually around 1.44 MB, and are outdated.
· Compact disks (CDs) can store up to 700 MB of data, mostly used for audio and small files.
· Optical disks such as DVDs and Blu-ray discs store more than CDs, but even Blu-rays max out around 25 -128 GB (approximately), much less than modern hard disks.
