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.
Cache Drives Give Your PC a Cheap SSD Boost. Many new PCs come with solid state drives because SSDs make booting up your PC and accessing data faster. But adding an SSD to an existing computer can be a problem. Most of us can't afford an SSD big enough to carry all our data. And combining an SSD with a traditional hard drive means lots of futzing to get all your most frequently accessed data onto the SSD drive. New solid state cache drives due from Corsair later this month should give upgraders a significant SSD speed boost without draining their wallets. The drives are relatively small and inexpensive: 30GB for $69, 45GB for $84 and 60GB for $99. But they come with software that analyzes what you use most frequently.
