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.
SSD (solid-state drive) A solid-state drive (SSD) is a nonvolatile storage device that stores persistent data on solid-state flash memory. Solid-state drives actually aren't hard drives in the traditional sense of the term, as there are no moving parts involved.
Solid state drives (SSDs) are starting to replace hard drives in more laptops, especially the new ultrathin laptops. These types of hard drives use a set of flash memory chips rather than a magnetic platter to store the data. They provide faster data access, lower power consumption, and higher reliability. The downside is that SSDs don't come in such large capacities as traditional hard drives. Plus, they usually cost a lot more.
