  • Calculations are based on SSD SATA 5000 2.5" and HDD 7200rpm SATA 2.5"
  • Mean time to failure (MTTF) rate [hours] 1: SSD 2,000,000; HDD 300,000. MTTF of a SSD is 6 times better than MTTF of a HDD.
  • According to industry analysts, the price of a 64GB SSD is expected to be $250 during 2009. This price is based on iSuppli report2.
  • The average annual IT employee salary in the US is $75,000.
  • The average annual laptop user salary in the US is $100,000.
  • Productivity when users are without their laptops falls on the average to 30%.
  • An average SSD will save 10% battery life compared to a HDD, depending on the laptop configuration3.
  • 1MTTF calculation is based on the Parts Stress Method, Telecordia SR-332.
