Advantages and Disadvantages of Hard Disk Drives

Hard disc drives, or simply hard drives are an essential component in any personal computer. Basically, it is a non-volatile hardware device that is used to permanently store and retrieve information. Hard disk drives (HDD) have been the medium of choice for secondary storage in computers; however there are now many alternatives due to improvements in technology. For instance, flash solid state drives (SSD) come in a variety of capacities and sizes that cover the needs of most individuals. Nevertheless, hard disk drives are still very popular among consumers and manufacturers for the reason that they are more affordable compared to SSD. Read on to learn about hard disk drive advantages and disadvantages.


Storage Capacity

These days, there are lots of hard disk drives that provide several terabytes storage capacity. In contrast, solid state drives do not hold quite as much because they become prohibitively costly over 2TB. With the large storage capacity offered by hard disk drives, PC users do not have to bother about their storage spaces running out too quickly. Also, the magnetic storage method of HDDs means that they have almost endless read/write capabilities. Very cool.


One of the main advantages offered by HDDs is that they are more affordable compared to SDDs with regard to dollar per gigabit. A solid state drive with the same storage capacity as a hard disk drive can be two times as costly. This implies that laptop or desktop computers with HDDs are a lot cheaper compared to their counterparts that are fitted with SSD storage devices. Extremely useful.

Life Span

Longevity with regard to read/write cycle is another benefit offered by HDDs. The flash memories contained in Solid state drives can be utilized only for a limited number of writes, unlike their HDD counterparts.



Hard disk drives are generally available in 2 sizes – 3.5 inch and 2.5 inch. The 2.5 inch drive is typically utilized in laptops while the 3.5 inch drive is often utilized in desktop computers. Even though size is not a problem with regard to internal hard disk drives, it is an issue for external hard drives as their convenience and portability is reduced. Memory cards, optical disks, and small USB thumb drives occupy less space and are a lot more portable compared to HDDs.


One big disadvantage of hard disk drives is that they are more vulnerable to data loss or integrity failure. The movable mechanical components of hard drives make them physically prone to mechanical damages as a result of drops and shudder.


Hard disk drives are available with various read/write speeds – depending on the device’s rotation per minute (RPM) specification. It should be noted that SSDs are faster compared to HDDs. For this reason, a PC that is fitted with a hard disk drive will boot slower compared to a PC fitted with a solid state drive. Make sense?
