Benchmark day 1: Seagate Barracuda 500GB (ST500DM002-1BD142)
En una charla con un viejo amigo sobre discos rígidos actuales puse de ejemplo algunos a los que he tenido acceso habitualmente. A partir de eso se me ocurrió tratar de determinar qué diferencia de rendimiento hay entre los discos de mi equipo hogareño y mi estación de trabajo, por lo que recurrí a las tradicionales herramientas de prueba en Linux.
La primera prueba va contra el disco de la estación de trabajo, siguen las especificaciones y más abajo los resultados por si a alguno le interesa. He remarcado los datos más relevantes.
