Well, I'm not a complete guru so maybe I'm wrong, but in a stripe the point is that you are pressing more platters into simultaneous service. There's a certain amount of synchronization because the things your computer needs at higher levels are spread across multiple disks, so it wants them at about the same time. If the first two disks provide the data quickly and the third doesn't, the system probably will have to wait for that third one before it can move on. Thats my suspicion anyways. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
