Hard drives come in multiple formats to allow users to store data in the most convenient way. It’s essential to keep important data such as documents, photos and videos protected and easy to access for your needs. The three main types of hard drives used currently are USB “thumb” drives, traditional Hard Disk Drives (HDD) that have been around for decades, and the newest form—Solid State Drive or SSD.
The Original – HDD
The first, and most common, type of hard drive is a standard HDD that goes inside of your desktop or laptop computer. It is the cheapest option and easy to locate at computer stores. The cost per gigabyte narrows down to from 20 to 30 cents per gigabyte, making it the most cost-effective storage solution. It is faster to access than a USB drive, but slower than the SSD.
Since the Hard Disk Drive uses mechanical parts to access data via moving heads and rotating platters, it is also subjected to failure with excess usage. When the drive first gets powered up after being turned off for any period of time, it needs to spin up. This also delays accessing the information which can result in a 5 to 10 millisecond wait before retrieving data. Additionally, data on a HDD has the tendency to become fragmented due to where it gets stored on the drive. This requires the drive to be defragmented occasionally to keep performance optimal. If you eventually get bad sectors it may take the use of a data recovery cable to recover this data.
