SSD Solid State Drive
  • Less power draw, averages 2 – 3 watts, resulting in 30+ minute battery boost
  • Expensive, roughly $0.10 per gigabyte (based on buying a 1TB drive)
  • Typically not larger than 1TB for notebook size drives; 1TB max for desktops
  • Around 10-13 seconds average bootup time
  • There are no moving parts and as such no sound
  • No vibration as there are no moving parts
  • Lower power draw and no moving parts so little heat is produced
     
  • Mean time between failure rate of 2.0 million hours
  • Generally above 200 MB/s and up to 550 MB/s for cutting edge drives
  • Full Disk Encryption (FDE) Supported on some models
  • Up to 30% faster than HDD
  • An SSD is safe from any effects of magnetism
HDD Hard Disk Drive
  • More power draw, averages 6 – 7 watts and therefore uses more battery
     
  • Only around $0.06 per gigabyte, very cheap (buying a 4TB model)
  • Typically around 500GB and 2TB maximum for notebook size drives; 6TB max for desktops
  • Around 30-40 seconds average bootup time
  • Audible clicks and spinning can be heard
  • The spinning of the platters can sometimes result in vibration
  • HDD doesn’t produce much heat, but it will have a measurable amount more heat than an SSD due to moving parts and higher power draw
  • Mean time between failure rate of 1.5 million hours
  • The range can be anywhere from 50 – 120MB / s
  • Full Disk Encryption (FDE) Supported on some models
  • Slower than SSD
  • Magnets can erase data
