HDD vs. SSD

The two main types of computer storage.

Hard Disk Drive (HDD)

HDDs are traditional storage devices that use spinning platters and a read/write head to store and retrieve data. They are a reliable, cost-effective, and high-capacity storage solution.

  • Capacity: Available in very large sizes (terabytes).
  • Cost: Much cheaper per gigabyte than SSDs.
  • Speed: Slower due to mechanical parts.
  • Durability: Susceptible to damage from drops.

Solid-State Drive (SSD)

SSDs use integrated circuits and flash memory to store data, with no moving parts. This makes them significantly faster and more durable than HDDs, becoming the standard for modern computing.

  • Capacity: Smaller capacities than HDDs for a comparable price.
  • Cost: More expensive per gigabyte.
  • Speed: Dramatically faster boot times and program loading.
  • Durability: Highly durable, as there are no moving parts.
