An internal hard drive is the primary storage device located inside a computer. It usually contains pre-installed software applications, the operating system and other important files. Some desktop computers have several internal hard drives, allowing them to provide greater data storage.
SSD stands for "Solid State Drive."Like a memory stick, there are no moving parts to an SSD. Rather, information is stored in microchips. Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD so much faster.
Up to 20x faster than a typical hard disk drive Faster boot-up and shutdown application load and response 240 GB read/write speeds of up to 530 MB/s/430 MBs Shock resistant for proven durability - even if you drop your computer
