Understanding Solid State Drive

Oct

1 tweet

A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. SSDs are distinguished from traditional hard disk drives (HDDs), which are electromechanical devices containing spinning disks and movable read/write heads. SSDs, in contrast, use microchips and data is retained in non-volatile memory chips[1]and contain no moving parts.[1] Compared to traditional HDDs, SSDs are typically less susceptible to physical shock, quieter, and have lower access time and latency. SSDs use the same interface as hard disk drives, thus easily replacing them in most applications.

Today, you can buy 60GB SSD for $100. For $100, you can buy 1.5TB of hard disk drive.
