ultra dma/133 y ultradma/100 hola mi pregunta es la siguiente si conecto dos discos duros unos de dma 133mb/s y otro de 100mb/s a traves del mismo cable el cual lleva yo calvijas para conectar dos discos, a la hora de transferir los datos me funcionaran ambos a la velocidad del mas lento? es decir a 100mb/s o no tiene nada que ver? |

Pon atención especialmente al segundo parrafo: Cita: El artículo completo aqui:It is a common misconception that, if two devices of different speed capabilities are on the same cable, both will necessarily transfer data at the speed of the slower device. This is true only with very old chipsets or add-in adapters. All modern ATA interfaces (since, at least, the late Pentium III and AMD K7 era) support independent timing, which allows each device on the cable to transfer data at its own best speed. However, due to the omission of both overlapped and queued feature sets from most real-world parallel ATA products, the preceding paragraph must be clarified. It applies to the data transfer phase, but this is usually the shortest part of a complete read or write operation. Devices do differ markedly in the total time required to perform an I/O (irrespective of the burst data transfer rate), and since only one device on a cable can have an operation in progress at one time, they do affect each others' performance. http://en.wikipedia.org/wiki/Advance...ogy_Attachment

entonces siempre funcionan a la velocidad del mas lento¿ eso me han dicho a mi que al conectarlos los dos por el mismo canal funcionan a la velocidad del mas lento es como si conectaras a un disco duro un lector del cd cuando estes leyendo un cd el disco duro te va a funcionar a la misma velocidad del cd es verdad? |
