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.

An SSD serves the same purpose as a (hard drive|hard drive), but uses flash memory rather than spindle of magnetic disks. It is called a solid state drive because it has no moving parts. Since SSDs do not need to move a physical drive head to read data, they can access data faster than hard drives.
