Dispositivos de almacenamiento de Datos

**__ Medidas de almacenamiento de la información __**

** Byte ** ** : ** unidad de información que consta de 8 bits; en procesamiento informático y almacenamiento, el equivalente a un único carácter, como puede ser una letra, un número o un signo de puntuación.

** Kilobyte ** ** (Kb) ** : Equivale a 1.024 bytes.

** Megabyte ** ** (Mb): ** Un millón de bytes o 1.048.576 bytes.

** Gigabyte ** ** (Gb) ** : Equivale a mil millones de bytes.

En informática, cada letra, número o signo de puntuación ocupa un **//byte//** (8 bits). Por ejemplo, cuando se dice que un archivo de texto ocupa 5.000 bytes estamos afirmando que éste equivale a 5.000 letras o caracteres. Ya que el byte es una unidad de información muy pequeña, se suelen utilizar sus múltiplos: kilobyte (Kb), megabyte (MB), gigabyte (GB)... Como en informática se utilizan potencias de 2 en vez de potencias de 10, se da la circunstancia de que cada uno de estos múltiplos no es 1.000 veces mayor que el anterior, sino 1.024 (210 = 1.024). Por lo que 1 GB = 1.024 MB = 1.048.576 Kb = más de 1.073 millones de bytes.

** Disco Duro ** ||
 * disco duro

**La estructura física del disco es:**

Se forma por platos (Platters), y en la superficie de cada uno de sus dos caras existen pistas (Tracks) concéntricas, que a la vez se dividen en sectores (Sectors). El disco tiene un cabezal (Head) a cada lado de cada plato que es movido por un motor servo cuando busca los datos almacenados en una pista y sector concreto. El concepto de cilindro (Cylinder) es un parámetro de organización: está formado por las pistas concéntricas de cada cara de cada plato, que están situadas unas sobre las otros, de manera que el cabezal no tiene que moverse para acceder a las diferentes pistas de un mismo cilindro.  Al referirnos a la organización lógica, lo que hacemos es agrupar los sectores en unidades de asignación (Clusters) que es dónde se almacenan los datos de manera organizada. Cada cluster sólo puede ser ocupado por un archivo (nunca dos diferentes), pero un archivo puede ocupar más de un cluster.  Al igual que la memoria, los discos duros también se pueden clasificar siguiendo unas características:

· **Velocidad de Rotación (RPM):** La velocidad a la cual giran los platos del disco, que es donde hay los datos. A más velocidad, más alta será la transferencia de datos (en Mbits/s), pero también será más ruidoso, y más cantidad de calor será disipada. · **Tiempo de Acceso (ms):** El tiempo mediano necesario, que tarda el cabezal por acceder a los datos solicitados. Aunque en realidad es una suma de tiempo: >> 1. El tiempo que tarde el disco al cambiar de un cabezal al otro al buscar los datos. >> 2. El tiempo que tarde el cabezal lector a buscar la pista con los datos, saltando de una al otro. >> 3. El tiempo que tarde el cabezal a buscar el sector correcto dentro la pista anteriormente encontrada. · **Tamaño de la caché/buffer (Kb/Mb):** El tamaño de la memoria internmedia, dónde se guardan temporalmente los datos que posteriormente serán enviadas hacia otro dispositivo. · **Tipo de conexión con el equipo (IDE, SCSI, USB):** Se diferencian en la velocidad, forma de transportar los datos, y los conectores.

El disco duro, también conocido como Hard Disk o HD, es el dispositivo magnético interno de la computadora en el que se almacena gran cantidad de información (programas, archivos, aplicaciones en general) y que es la parte principal de lo que se conoce como memoria secundaria. Está compuesto por dos tipos de estructuras: una física y una lógica. La primera se refiere a las piezas físicas que la integran, entre las que se encuentran los discos o platos (donde se graban los datos), los cabezales de lectura/escritura (que leen o escriben los datos de los discos y son dos por disco), e impulsor de cabezales (motor que mueve los cabezales), las pistas (sendas concéntricas donde se almacenan los datos) y los cilindros (pistas de todos los discos internos que coinciden en forma vertical). En cuanto a la estructura lógica, está formada por el sector de arranque (primer sector del disco donde se almacenan las tablas de particiones), espacio particionado y sin particionar, la tabla de asignación de ficheros o FAT (que informa al DOS los espacios libres), el directorio raíz y la zona de datos para archivos y subdirectorios. Una de sus características básicas es su tamaño o alta capacidad de almacenamiento, la que se mide en Megabytes (MB) o Gigabytes (GB) y también su desempeño, que se mide justamente por su capacidad de almacenamiento, el tiempo de búsqueda, el tiempo de acceso y la tasa de transferencia de datos.
