Un fujitsu SATA de 5400RPM... muchisimo mejor rendimiento... aun no he probado que tanto consume de batería extra, pero en cuanto a desempeño, es tremendo comparado con lo que cuesta un SDD.

Curiosamente aunque las velocidades que marca hdparm son cercanas el desempeño trabajando si es bastante notorio... a seguir probando... 120GB vs 4GB.
