Top and bottom sides of a 100GB Intel DC S3700 SATA SSD and a 120GB Intel 535 mSATA SSD. Flash memory, a key component in modern SSDs, was invented in 1980 by Fujio Masuoka at Toshiba. [ 132 ] [ 133 ] Flash-based SSDs were patented in 1989 by the founders of SanDisk , [ 134 ] which released its first product in 1991: a 20 MB SSD for IBM laptops ...
An SSD, in form of a 2.5-inch bay device that uses Serial ATA (SATA) interface Internals of an SD card , showing the flash memory and controller integrated circuits A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers , embedded systems , portable devices , large servers and network ...
The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...
In computer storage, a disk buffer (often ambiguously called a disk cache or a cache buffer) is the embedded memory in a hard disk drive (HDD) or solid-state drive (SSD) acting as a buffer between the rest of the computer and the physical hard disk platter or flash memory that is used for storage.

The Enterprise and Data Center Standard Form Factor (EDSFF), previously known as the Enterprise and Data Center SSD Form Factor, is a family of solid-state drive ...
With Open Channel SSDs the L2P table is stored in host memory and the host CPU maintains that table. While the Open Channel SSD approach is more flexible, a significant amount of host memory and host CPU cycles is required for L2P management. With an average write size of 4 KB, almost 3 GB RAM is required for an SSD with a size of 1 TB. [9]
1 GiB of SDRAM mounted in a computer.An example of primary storage. 15 GB PATA hard disk drive (HDD) from 1999. When connected to a computer it serves as secondary storage. 160 GB SDLT tape cartridge, an example of off-line storage.
The board solid-state drive, commonly referred to as the BSSD, is an implementation of a regular SSD, but in a different form factor and packaging, which is perhaps optimized for certain aspects of the storage device, such as cost or density. [1] The term board in BSSD refers to the printed circuit board (PCB), [2] from references to on-board ...
