Storage

Computers need to be able to store programs and data when the power is switched off. Secondary storage is used to hold data and programs when the computer is not in use.

Suitable devices and storage media for a given application

The choice of secondary storage medium depends on the use it is required for. When deciding on the type of device needed, a user should consider:

  • Cost - what is the cost per gigabyte (GB)?
  • Capacity - how much data can the medium hold?
  • Speed of access - how quickly can data be transferred to and from the medium?
  • Portability - how portable is the medium? Does it need to be portable?
  • Durability - how robust is the medium, and how robust will it need to be?
  • Reliability - how resilient and long-lasting is the medium?

Once these factors are taken into consideration, an appropriate choice can be made.

MediumTypeCapacitySpeed of accessPortabilityDurabilityReliabilityTypical use
Hard disk Magnetic 500 GB-12 TB Slow Internal devices are fixed. External hard disks are portable Reasonable, but prone to damage if dropped or knocked Generally very reliable if looked after Long-term storage of programs and data
CD-ROM/R Optical 640 MB Very slow Very portable Easily scratched, damaged or broken Generally very reliable if looked after Backups, archives, copies of data, distribution of programs and music
CD-RW Optical 640 MB Very slow Very portable Easily scratched, damaged or broken Generally very reliable if looked after Copies of data, transferring files between computers
DVD-ROM/R Optical 4.7 GB Slow Very portable Easily scratched, damaged or broken Generally very reliable if looked after Backups, copies of data, distribution of games, TV programmes and movies
DVD-RW Optical 4.7 GB Slow Very portable Easily scratched, damaged or broken Generally very reliable if looked after Backups, archives, copies of data
Blu-ray-ROM/R Optical 50 GB Slow Very portable Easily scratched, damaged or broken Generally very reliable if looked after Distribution of TV shows and movies
Blu-ray-RW Optical 50 GB Slow Very portable Easily scratched, damaged or broken Generally very reliable if looked after Backups, archives
Solid-state drive Flash memory 256 GB-4 TB Very fast Internal devices are fixed. External hard disks are portable Robust and resilient Reliable Long-term storage of programs and data where high performance is required
USB memory stick Flash memory 2 GB-2 TB Fast Very portable Robust and resilient Reliable Copies of data, transferring files between computers

In many situations, more than one type of secondary storage may be suitable. For example, a USB stick or a CD-RW may be used to transfer files, or to back up data.

Which of the following is a concept that applies only to conventional magnetic hard disk drives and not newer solid

Which of the following is a concept that applies only to conventional magnetic hard disk drives and not newer solid-state drives? D. Each concept applies to both HDDs and SSDs except for platter spin rates. Revolutions per minute (rpm) measurements refer to drives with moving parts.

Which storage device is typically not removable?

CD-ROM, DVD-ROM, and BD-ROM refer to read-only optical storage disks. The data written on them is permanent and cannot be removed or overwritten. This is why they can't be used as a personal storage. Instead, they are typically used for software installation programs.

What kind of media is most commonly used when large amounts of data need to be archived on a regular basis?

Although many storage administrators are now choosing disk as the media of choice for backups, tape storage media remains the most widely used archive media mostly because of its cost-to-capacity ratio, but also due to a very broad and well-established implementation base.

When installing multiple add on cards of the same type which type of cards might the user need to bridge together to function as a single unit?

When installing multiple add-on cards of the same type, which type of cards might you need to bridge together to function as a single unit? PCIe video cards may be bridged together, enabling two cards to function as one system.
