Tech 101: Traditional Hard Drives Vs. Solid State Drives

Most people are familiar with hard drives, but we often get questions about the differences between solid-state drives and hard disk drives - SSDs and HDDs. While both accomplish the basic task of storing data, solid-state drives are the future of everything from office work to gaming at home because of their stunning load times and enhanced reliability.

Learn about 5 ways technology is transforming businesses in 2020.

According to Computer Hope, a traditional hard drive, also known as a hard disk drive (HDD), is a nonvolatile memory hardware device that permanently stores and retrieves information. They can be found in desktop computers, mobile devices, consumer electronics and enterprise storage arrays in data centers. Basic hard drives consist of one or more platters to which data is written using a magnetic head, that are positioned around a spindle inside of an air-sealed casing. Think of it as an old record player. The motor is used to spin the platters (record), which hold the data (songs), up to 15,000 rotations per minute. As the platters spin, a second motor controls the position of the read-and-write heads (stylist or needle) that records information to and from tracks on each platter. The biggest advantage to a traditional hard drive is that you can store lots of data cheaply.

Due to the spinning plates, the hard drives can generate noise, produce heat, become power hungry, and they don’t work nearly as fast as SSDs. Overall, these hard drives will wear out wear out more quickly over time compared to solid state drives.

Unlike traditional state drives, solid state drives (SSD), do not have any moving parts. SSD stores information through a microchip rather than a read and write head. That’s the key difference between the two because rather than using disks, motors, and read/write heads, SSDs uses flash memory instead, which retains the information even when the power is turned off.

SSD performance is considered much faster, quieter, and more durable than HDDs. Due to their lack of moving parts, SSDs are less likely to break down, but they do have a set life expectancy, meaning there is a limit to how many times they can be written to and read form before they stop working.

SeedSpark's recommendation is almost always a solid-state drive, especially for laptops and on-the-go storage solutions. The absence of moving parts makes the SSD a better option because of its ability to handle the bumps and dings of everyday life with no risk of damaging fragile internal components. In addition to being great for mobility, the advanced read write times - the speed of your hard drive - goes a long way in keeping your system running full-steam ahead, even with multiple applications open at once. As technology has improved, the price of SSDs has dropped significantly, making them a more viable option even for those on a tight budget.
