despite the "SATA II" moniker, the WD2500KS does not implement SATA Native Command Queuing (NCQ). Though competitors such as Seagate and Maxtor have commenced with NCQ inclusion even on desktop-oriented drives, WD claims that NCQ does not help and can even hurt single-user performance.

JP-- Escreveu:SATA II n está relacionado com o NCQ. O 1º é a velocidade máxima do método de transferência e o 2º é um método de busca de dados no disco.
The term SATA II has grown in popularity as the moniker for the SATA 3Gb/s data transfer rate, causing great confusion with customers because, quite simply, it’s a misnomer.
The first step toward a better understanding of SATA is to know that SATA II is not the brand name for SATA’s 3Gb/s data transfer rate, but the name of the organization formed to author the SATA specifications. The group has since changed names, to the Serial ATA International Organization, or SATA-IO.
The 3Gb/s capability is just one of many defined by the former SATA II committee, but because it is among the most prominent features, 3Gb/s has become synonymous with SATA II. Hence, the source of the confusion.
