Disproportionation is a specific type of redox reaction in which a species is simultaneously reduced and oxidised to form two different products.he oxidation state of oxygen is -1/2 in the superoxide free radical anion, -1 in hydrogen peroxide and 0 in dioxygen. 1  In the Cannizzaro reaction, an aldehyde is converted into an alcohol and a carboxylic acid. 2  In the related Tishchenko reaction, the organic redox reaction product is the corresponding ester.
A solid-state drive (SSD, also known as a solid-state disk) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently.
Flash RAM: Silicon chips that, unlike other types of RAM, can hold data without an electric current--a feature that makes them useful for storage. (RAM stands for Random Access Memory.) SSD: Solid state drive. Flash memory packaged in an HDD-like form factor, to be used in place of a hard drive. SSDs are generally faster than HDDs, use less power, and are less likely to be damaged by a fall or shock.
