This is not the first time the President has been criticized for taking a vacation during an urgent situation. During Obama's first term in 2009, Obama addressed the Underwear Bomber situation on television from Hawaii. On the other hand, in 2012 Obama flew back to the mainland midway through his vacation in order to deal with the fiscal cliff negotiations. This year critics cited the recent Sony hack attack as a reason for the president to delay his trip.

Unlike a hard drives, an SSD has no moving parts, which gives it advantages such as accessing stored information faster, no noise, often more reliable, and consume less power. The picture shows a Crucial SSD and is an example of an SSD. The first SSD was implemented in IBM supercomputers in the 1970s and 1980s. They have since been drastically improved upon and offer storage capacities of 128GB and 256GB for home computers.
