Which storage device is typically used for backing up a home computer system?

• A. HDD
• B. Magnetic tape
• C. SD card
• D. USB flash drive

Answer: (A)

Backups need a storage option that offers large capacity at a reasonable cost so you can regularly save a full set of your files and system data. A hard disk drive, especially as an external drive, fits this role well. It provides lots of space per dollar, is straightforward to set up, and you can use it for automated or scheduled backups without spending a fortune. Magnetic tape is typically used in professional environments for archival storage and requires specialized hardware, making it impractical for most home setups. SD cards have limited capacity and shorter durability for large, ongoing backups, and USB flash drives, while handy for transferring small files, become expensive per gigabyte and don’t wear as well under the heavy write loads of full-system backups.
