What key feature makes magnetic storage less suitable for portable devices?

• High energy usage

• Needs internet access

• Fragile due to moving parts

• Reflects light poorly

Why might solid-state storage be preferred when filming with drones?

• It’s cheaper than magnetic storage

• It can be written to with lasers

• It resists damage from movement

• It holds more data than DVDs

Which of the following most accurately explains why magnetic storage offers high capacity?

• It uses deep pits and lands on a disc surface

• It magnetises microscopic areas on a spinning disk

• It stores binary data using transistors

• It compresses data into very small bits

Which of the following is NOT a reason why optical storage has declined in everyday use?

• It has limited storage capacity

• It requires a separate disc reader

• It costs more per gigabyte than SSDs

• It reads/writes more slowly

What makes solid-state storage faster than traditional magnetic storage?

• It spins faster than magnetic disks

• It uses lasers instead of mechanical heads

• It transmits binary signals via fibre

• It has no moving parts and uses flash memory

Which is the best reason magnetic storage is still used for school server backups?

• It’s more secure than optical discs

• It can store large amounts of data cheaply

• It is the fastest storage for large files

• It reads files using lasers

How does a disc drive detect data from an optical disc?

• It senses magnetic pulses

• It detects how pits and lands reflect laser light

• It uses transistors to read voltage

• It interprets mechanical rotations into binary

Which physical property of SSDs increases their durability?

• They are built into plastic cases

• They reflect light well

• They have no moving components

• They magnetise electrons

A student wants to archive a media collection in a low-cost, portable format. Which storage is most suitable?

• SSD

• HDD

• Optical disc

• NVMe drive

Which factor is a disadvantage of solid-state storage for large archival projects?

• Data loss from magnetic fields

• High price per gigabyte

• Need for spinning disks

• Need for special laser readers
