  1. SPEED: SSD has lower latency and faster read/writes
  2. HEAT, ELECTRICITY, NOISE: Since no such rotation is needed in solid state drives, they use less power and do not generate heat or noise
  3. COMPONENTS: SSD has no moving parts; it is essentially a memory chip. It is interconnected, integrated circuits (ICs) with an interface connector. There are three basic components – controller, cache and capacitor
  4. WEIGHT: SSD drives are lighter than HDD because they do not have the rotating disks, spindle and motor
  5. DEALING WITH VIBRATION: SSD drives very resistant to shock and can withstand vibration up to 2000Hz
  6. COST: It is more expensive than HDD,which is RM1.80/GB

  1. SPEED: HDD has higher latency, and longer read/write times
  2. HEAT, ELECTRICITY, NOISE: Hard disk drives use more electricity to rotate the platters, generating heat and noise
  3. COMPONENTS: HDD contains moving parts – a motor-driven spindle that holds one or more flat circular disks (called platters) coated with a thin layer of magnetic material. Read-and-write heads are positioned on top of the disks; all this is encased in a metal cas
  4. WEIGHT: HDDs are heavier than SSD
  5. DEALING WITH VIBRATION: The moving parts of HDDs make them susceptible to crashes and damage due to vibration
  6. COST: It is much cheaper than SSD

             Overall, HDDs win on price, capacity, and availability. SSDs work best if speed, ruggedness, form factor, noise, or fragmentation (technically part of speed) are important factors to you. If it weren’t for the price and capacity issues, SSDs would be the winner hands down.
