Solid-state drive

Solid-state drive definition

Solid-state drive refers to a type of non-volatile storage device that stores persistent data on solid-state flash memory. Unlike traditional hard disk drives (HDDs), which use spinning disks and moving read/write heads, SSDs have no moving parts, which offers a range of advantages such as speed and durability. While SSDs are the dominant technology now for high-speed storage, new technologies such as MRAM (Magnetoresistive Random Access Memory) capable of replacing SSDs are being developed.

Solid-state drive benefits over HDDs

  1. Speed. They have faster read and write speeds compared to HDDs, offering significant improvements in toot times, file transfer speeds, and application loading times.
  2. Durability. Without moving parts, SSDs are generally more resistant to physical shocks, making them suitable for various mobile devices.
  3. Noise. They don’t produce the noise associated with the spinning disks and moving heads.
  4. Power consumption. They consume less power than HDDs, leading to longer battery life.
  5. Heat production. SSDs produce less heat compared to HDDs.
  6. Form factors. They can be found in various form factors, including 2.5-inch, M.2, and U.2, which allows for innovative designs in computer and device manufacturing.
  7. Latency. They generally have lower latency than HDDs, which means they can deliver data more quickly.
