Las dos seagate a 7200RPM, 16MB de cache, estaba tentado a comprar un Western Digital que se supone tiene 32MB de cache por el mismo precio, pero el tama\u00f1o y seg\u00fan temperatura del seagate me convencieron por mucho, ahora seg\u00fan hdparm la diferencia no es tanta (en el cached reading en el buffered si se nota), sin embargo en un escenario real el uso de PATA requiere de interrupci\u00f3n NMI y de tiempo del CPU vs SATA que es transparente y del cual se encarga el chipset directamente supongo con otro tipo de interrupci\u00f3n de menor costo al sistema, lo cual a\u00fan cuando en tiempos son muy similares redunda en mayor desempe\u00f1o para el SATA… claro que tengo que investigar un poco mas puesto que esto tan solo es lo que se de un par de le\u00eddas muy superficiales, \u00bfsugerencias? todav\u00eda estoy probando sda aunque empece con ext3, tengo ganas de probar ext4 o alguno de los nuevos sistemas de archivos, se que es una unidad relativamente peque\u00f1a, 500GB pero estoy pensando m\u00e1s en tener 3 de 500GB + 1 de 1.5TB a tener 3 de 1.5TB, primero por costo, segundo por la probabilidad de tener m\u00e1s de una de un solo lote y la mortandad infantil, bueno por ah\u00ed vi una prueba interesante que debo buscar, para desempe\u00f1o de FS :D<\/p>\n","protected":false},"excerpt":{"rendered":"
