Understanding the advantages and disadvantages of different storage devices

• What is another term for secondary storage?

  Non-volatile storage
• Secondary storage is non-volatile
• What are examples of secondary storage devices?

  HDD, SSD, USB drive
• Arrange the secondary storage devices from slowest to fastest in terms of data access speed:

  1️⃣ Hard Disk Drive (HDD)

  2️⃣ Optical Discs

  3️⃣ USB Flash Drive

  4️⃣ Solid State Drive (SSD)
• Primary storage is slower than secondary storage.

  False
• What is a major disadvantage of Hard Disk Drives (HDDs)?

  Slower access times
• HDDs have slower access times compared to SSDs due to their moving parts.

  True
• Why do SSDs have faster access times than HDDs?

  No moving parts
• Secondary storage retains data even when the computer is turned off.


  True
• What type of storage loses data without power?

  Primary storage
• Secondary storage is generally slower than primary storage.


  True
• Order the secondary storage devices by data access speed from fastest to slowest:

  1️⃣ SSD

  2️⃣ USB Flash Drive

  3️⃣ Optical Disc

  4️⃣ HDD
• HDDs are more susceptible to physical damage than SSDs due to their moving parts.


  True
• Which type of secondary storage device is more vulnerable to physical shocks and vibrations?

  Hard Disk Drives
• HDDs offer very high storage capacities, often in the range of hundreds of gigabytes to terabytes.


  True
• HDDs have slower access times due to their moving parts
• What is the typical storage capacity range of USB flash drives?

  8GB to 256GB
• USB flash drives offer a lower cost per gigabyte of storage compared to HDDs.

  False
• Order the following storage devices from highest to lowest cost per GB:

  1️⃣ SSDs

  2️⃣ USB Flash Drives

  3️⃣ HDDs

  4️⃣ Optical Discs
• Data stored in RAM is retained after the computer is restarted.

  False
• What does HDD stand for?

  Hard Disk Drive
• SSDs use flash memory chips and have no moving parts
• Match the secondary storage device with its description:

  Hard Disk Drive (HDD) ↔️ Magnetic disk-based storage

  Solid State Drive (SSD) ↔️ Uses flash memory chips

  USB Flash Drive ↔️ Portable and removable storage

  Optical Discs ↔️ Uses laser technology
• Compared to primary storage, secondary storage has higher access times
• Why are Hard Disk Drives (HDDs) susceptible to physical damage?

  They have moving parts
• What is the typical storage capacity range of HDDs?

  Hundreds of GB to TB
• HDDs have a lower cost per gigabyte
• What is a major disadvantage of HDDs regarding physical durability?

  Susceptibility to shocks
• HDDs consume more power than SSDs, affecting battery life in portable devices.


  True
• Current SSDs typically offer lower maximum storage capacities
• What are examples of secondary storage devices?

  HDD, SSD, USB drive
• HDDs have slower data retrieval speeds due to mechanical read/write heads
• What is the main reason SSDs have faster access times compared to HDDs?

  No moving parts
• SSDs generally have a higher cost per gigabyte of storage compared to HDDs.


  True
• Cloud storage requires a stable internet
• What is the maximum storage capacity of a Blu-ray disc?

  50GB
• Optical discs are a good low-cost option for moderate storage needs.
