SCSI(Small Computer System Interface)小型电脑系统接口的规范,以往大多使用在小型电脑、服务器或是工作站上。所以在大部分个人电脑用户的印象之中,简直就是昂贵的代表,尤其是现今,当各种IDE接口、RS-232接口以及USB接口的设备大量充斥市场,价格也日益下滑之际,更显出SCSI设备的高贵。不过近年来SCSI用户越来越多,以往高如天价的设备也由于应用的层面越来越广而趋于平民化。SOSI的规范从发展至今经历了不少的变革,从早期的SCSI-1、SCSI-2…,一直到现在的Ultra 2 Wide SCSI的传输速率已达80MB/sec.甚至Ultra 160(传输速率达160/MB),也即将有发烧产品上市了,远远将UDMA/66的传输速率抛在脑后。且由于SCSI本身是采用总线结构的传输方式,也远比IDE接口节省系统资源,能更有效的发挥电脑的作用。对SCSI卡不太认识的读者,正可借此一窥SCSI卡之奥秘。
SCSI (Small Computer System Interface) small computer system interface specification, mostly used in small computers, servers or workstations. Therefore, the impression of most PC users, is simply an expensive representative, especially today, when a variety of IDE interface, RS-232 interface and USB interface devices flooding the market, the price is declining, the more obvious A noble SCSI device. However, more and more SCSI users in recent years, in the past as high as the price of the device is also due to the increasingly wide range of applications tend to be civilians. The SOSI specification has undergone many changes so far, from the early SCSI-1, SCSI-2 ... and up until now the Ultra 2 Wide SCSI transfer rate has reached 80MB / sec. Even the Ultra 160 (transfer rate up to 160 / MB), also about fever products on the market, far away from the UDMA / 66 transfer rate behind. And because SCSI itself is the bus structure of the transmission, but also save system resources than the IDE interface, can more effectively play the role of the computer. Readers who are not familiar with SCSI cards can take a peek at the mysteries of SCSI cards.
