Solid State or Hard Drive?

The most widely used secondary storage method that’s been used for decades has been the Hard Disk Drive (HDD). A HDD is a data storage device uses which consists of platters coated in magnetic material and magnetic heads arranged on a moving actuator arm which reads and writes data to the platter surfaces. Up until recently,  the HDD was left unchallenged. It’s rival has become popular over the past five years, the Solid State Drive (SSD).

     A solid-state-drive is built like a very large memory stick, or flash drive. Unlike the HDD, a solid state drive doesn’t have have moving mechanical parts. Due to the architectural nature of SDD’s, the seek time is drastically reduced compared to a HDD. One of the main issues of HDD’s is the mechanical parts break down, making the content on the HDD unreachable. A SDD also doesn’t generate as much heat, and compared to it’s counterpart, it’s completely silent. By not having any moving parts, the SSD is also much more durable, if dropped or shaked, it is less likely to be damaged.
