โซลิดสเตตไดรฟ์ (Solid state drive : SSD) คือ อุปกรณ์จัดเก็บข้อมูลชนิดหนึ่ง ที่ใช้ solid-state memory เพื่อจัดเก็บข้อมูลแบบถาวรเหมือนฮาร์ดดิสก์
SSD ทำตัวเสมือนอุปกรณ์ฮาร์ดไดรฟ์ โดยอาจใช้ SRAM หรือ DRAM หรือหน่วยความจำแฟลช มักเรียกว่า RAM-drive

A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive interface, thus easily replacing it in most applications. An SSD using SRAM or DRAM (instead of flash memory) is often called a RAM-drive, not to be confused with a RAM disk.
The original usage of the term solid-state (from solid-state physics) refers to the use of semiconductor devices rather than electron tubes, but in this context, has been adopted to distinguish solid-state electronics from electromechanical devices as well. With no moving parts, solid-state drives are less fragile than hard disks and are also silent (unless a cooling fan is used); as there are no mechanical delays, they usually employ low access time and latency.
Well , next entry about ssd will be it's history .
