Le site CoolTechZone vient de publier un article expliquant les méandres de la technologie NCQ (Native Command Queuing) que commence à intégrer certains disques durs :
" Native Command Queuing (NCQ) orders each target logical block address (LBA), or bit of data, in a queue, in order to maximize efficiency and minimize latencies. You can think of these logical block addresses as addresses for houses in a neighborhood. It would be pointless to deliver newspapers to a house right next door, go to a house two miles away, back to another house near the first delivery, and finally deliver the last newspaper to another house in the same vicinity. You have just wasted an enormous amount of time. "
