SATA II, limitação por jumper (padrão de fábrica)

Posted by Felipe Olivaes in Hardware

em alguns HD´s da SeaGate HD Sata II, ele já vem jumpeado de fábrica limitando a sua velocidade em SATA I para manter compatibilidade com todas mother boards.

A diferença de velocidade é absurda, simplismente o dobro. Se você não retirar o jumper, seu HD irá funcionar somente com a metade da velocidade.

Velocidades:
HD SATA (1.5 Gb/s)
HD SATA II (3.0 Gb/s)

então fique ligado, verifique o jumper do hd para não perder performace…
