12 Facts About SSD

Key components of an SSD are the controller and the memory to store the data.

The primary memory component in an SSD was traditionally DRAM volatile memory, but since 2009, it is more commonly NAND flash non-volatile memory.

Every SSD includes a controller that incorporates the electronics that bridge the NAND memory components to the host computer.

Flash-based SSD typically uses a small amount of DRAM as a volatile cache, similar to the buffers in hard disk drives.

Since an SSD is made up of various interconnected integrated circuits and an interface connector, its shape is no longer limited to the shape of rotating media drives.

An SSD can be completely integrated in the other circuitry of the device, as in the Apple MacBook Air .

The SSD was designed to be installed permanently inside a computer.

Endurance of an SSD should be provided on its datasheet in one of two forms:.

In 2011, Intel introduced a caching mechanism for their Z68 chipset called Smart Response Technology, which allows a SATA SSD to be used as a cache for a conventional, magnetic hard disk drive.

Scalable block layer for high-performance SSD storage, known as blk-multiqueue or blk-mq and developed primarily by Fusion-io engineers, was merged into the Linux kernel mainline in kernel version 3.

One of the first mainstream releases of SSD was the XO Laptop, built as part of the One Laptop Per Child project.

In November 2010, Fusion-io released its highest performing SSD drive named ioDrive Octal utilising PCI-Express x16 Gen 2.
