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.
But the reality is that you'll still pay a significant premium for SSD-equipped laptops compared to old-fashioned platters. For example, a typical 256GB SSD drive costs between $180-$250 today. If it could physically fit in a laptop, you'd be able to pack 4TB (that's 4 terabytes) for the same amount of money.
