Concepts inMigrating server storage to SSDs: analysis of tradeoffs

Solid-state drive

A solid-state drive (SSD), sometimes called a solid-state disk or electronic disk, is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block I/O hard disk drives.  more from Wikipedia

Server (computing)

In the context of client-server architecture, a server is a computer program running to serve the requests of other programs, the "clients". Thus, the "server" performs some computational task on behalf of "clients". The clients either run on the same computer or connect through the network. In most common use, server is a physical computer dedicated to running one or more such services, to serve the needs of users of the other computers on the network.  more from Wikipedia

Serial ATA

Serial ATA (SATA or Serial AT Attachment) is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives.  more from Wikipedia

Laptop

A laptop computer is a personal computer for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad or pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. Laptops are also sometimes called notebook computers or notebooks.  more from Wikipedia

Desktop computer

A desktop computer is a personal computer (PC) in a form intended for regular use at a single location, as opposed to a mobile laptop or portable computer. Early desktop computers are designed to lay flat on the desk, while modern towers stand upright. Most modern desktop computers have separate screens and keyboards. Prior to the widespread use of microprocessors, a computer that could fit on a desk was considered remarkably small.  more from Wikipedia

Dynamic random-access memory

Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically.  more from Wikipedia

Flash memory

Flash memory is a non-volatile computer storage chip that can be electrically erased and reprogrammed. It was developed from EEPROM (electrically erasable programmable read-only memory) and must be erased in fairly large blocks before these can be rewritten with new data. The high density NAND type must also be programmed and read in (smaller) blocks, or pages, while the NOR type allows a single machine word (byte) to be written or read independently.  more from Wikipedia

Data center

A data center or data centre or computer centre (also datacenter or datacentre) is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g. , air conditioning, fire suppression) and security devices.  more from Wikipedia
