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.
Solid State Drive (SSD). A SSD comes in traditional HDD form factors such as 5.25-inch, 3.5-inch, 2.5-inch or 1.8-inch.The largest size, 5.25-inch, is not widely used, except for special-purpose appliances, such as backup devices. 1.8-inch SSDs are used in removable and ultramobile applications..5-inch and 2.5-inch are the most common HDD form factors, and the same holds true for SSDs, as they will fit into the same slots as the identical size HDDs. 3.5-inch SSD. 2.5-inch SSD. 1.8-inch SSD.
