Como testear la velocidad de lectura/escritura de un disco rigido

on Mar 06, 2016

Para probar la velocidad de lectura abrimos una terminal y ejecutamos el siguiente comando

for i in 1 2 3; do sudo hdparm -tT /dev/sda; done

Para que los resultados de lectura sean significativos es necesario repetir el proceso 2 o 3 veces y obtenemos el siguiente resultado

/dev/sda:
Timing cached reads: 8124 MB in 2.00 seconds = 4065.28 MB/sec
Timing buffered disk reads: 810 MB in 3.00 seconds = 269.71 MB/sec

/dev/sda:
Timing cached reads: 8202 MB in 2.00 seconds = 4103.81 MB/sec
Timing buffered disk reads: 826 MB in 3.00 seconds = 275.17 MB/sec

/dev/sda:
Timing cached reads: 8232 MB in 2.00 seconds = 4119.05 MB/sec
Timing buffered disk reads: 828 MB in 3.00 seconds = 275.79 MB/sec

Timing Cached reads: Es la velocidad de lectura de la información almacenada en la cache de disco
