SSDs vs. HDDs

 

Buying a new computer or laptop can be confusing. One of the most important features to look for is how the device will access internal information, including your files and programs. The most common types of hard drives available today are SSDs (solid state drives) and HDDs (hard disc drives).

SSDs store information in microchips, and are a newer storage option when compared to hard disc drives. This type of storage is also sometimes called flash memory. HDDs access information with a moving read/write arm, and information is physically stored on spinning storage platters in your laptop, computer or external hard drive. Before you make a decision, check out to learn more about each storage type.

SSDs

 

Advantages of SSDs

  • Faster storage - An SSD has no moving parts, so information can be accessed much faster than HDDs. This also means that they can be physically smaller, which is great for ultra-thin laptops and other portable devices.
  • More durable - SSDs are better suited for users who can be rough with equipment, since the moving read/write arm and platters are more prone to damage from dropping or shaking.
Solid state drive
  • Physically smaller - SSDs may have the same form factor as HDDs, but this is for compatibility. Microchip storage can fit into smaller devices, such as paper-thin laptops and tablets.
  • Quiet - SSDs do not make noise, so you can get right to work and only hear the tapping of your fingertips against the keyboard.


Limitations of SSDs

  • More expensive - Because of the newer technology, SSDs can also be more expensive.
  • Smaller capacity - You also might have fewer options if you need a large amount of storage.
  • Less available - For high-capacity applications like servers or performance desktop computers, you might not be able to find as many SSDs due to the higher price and newer technology.

HDDs

 

Hard disc drive

Advantages of HDDs

  • Cost-effective storage - This technology has been around for quite a while, so data storage in this medium is more affordable.
  • High capacity - HDDs typically have more storage volume than SSDs, so this type could be right for you if you need a large hard drive to store a lot of media.
  • Easily available - From economy to high-speed models, an incredible variety of HDDs are available in laptops, desktops and other storage media on the market today.

Limitations of HDDs

  • Slower - HDDs move the mechanical arm to access or store data, so this method is slower than its nonmoving counterpart.
  • More fragile - If a laptop is broken or jostled, the hard drive can more easily become damaged because of the various internal parts.
  • Larger - Due to the physical space needed for this type of storage, thinner laptops are less likely to use HDDs. An HDD can potentially place limitations on how small a device can be manufactured.
  • Louder - You'll likely hear soft clicks, vibration and spinning while the computer is retrieving information.
