Linux Essentials (010-160) — Question 41

What are the differences between hard disk drives and solid state disks? (Choose two.)

Answer options

• A. Hard disks have a motor and moving parts, solid state disks do not.
• B. Hard disks can fail due to physical damage, while solid state disks cannot fail.
• C. Solid state disks can store many times as much data as hard disk drives.
• D. /dev/sda is a hard disk device while /dev/ssda is a solid state disk.
• E. Solid state disks provide faster access to stored data than hard disks.

Correct answer: A, E

Explanation

Option A is correct because hard disks have mechanical parts that can fail, while solid state disks are devoid of moving components. Option E is also correct since solid state disks typically have faster read/write speeds compared to hard disks. Options B and C are incorrect because solid state disks can fail, albeit differently than hard disks, and while solid state disks generally have higher capacities, this is not universally true. Option D is incorrect because /dev/ssda is not a standard device name for a solid state disk.
