Which storage device is the most economical for storing large amounts of data?

• A. SSD
• B. CD-ROM
• C. Hard Disk
• D. USB Drive

Answer: (C)

For storing large amounts of data, the key is cost per gigabyte. A hard disk delivers the most data per dollar among common consumer storage options, thanks to mature manufacturing, high storage densities, and large-capacity models that keep the price per GB very low. SSDs bring speed and responsiveness but cost more per gigabyte, especially at larger capacities. USB drives are convenient for portability but their cost per gigabyte tends to be higher than HDDs when you compare similar total sizes. CD-ROMs hold limited data per disc and require many discs to reach large totals, making the cost per gigabyte impractical for big data. So, the hard disk is the most economical choice for storing large amounts of data.
