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.
HDDs predominantly use SATA interface. The most common size for laptop hard drives is the 2.5â form factor while a larger 3.5â form factor is used in desktop computers. The larger size allows for more platters inside and thus more storage capacity. Some desktop hard drives can store up to 6TB of data!
