SOLID STATE DRIVES. By: Vaibhav Talwar UE84071 EEE(5th Sem ). INTRODUCTION. A solid-state drive (SSD) - It is a data storage device that uses solid-state memory to store persistent data.
A solid-state drive (SSD)-
It is a data storage device that uses solid-state memory to store persistent data.
SSDs, use microchips, and contain no moving parts. 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.
1950- core memory and Card Capacitor Read Only Store (CCROS).
1980s- SSDs were implemented in semiconductor memory for early supercomputers of IBM, Amdahl and Cray.
1978- Texas Memory Systems introduced a 16 kilobyte (KB) RAM solid-state drive to be used by oil companies for seismic data acquisition.
1995- M-Systems introduced flash-based solid-state drives.
2003 - Terabyte SSDs become commercially available In February 2003 Competitors Texas Memory Systems and Imperial Technology announced the world's first terabyte class SSD
May 2006 - Samsung launched the world's first high volume Windows XP notebook using SSDs.
