Hi Tejun, I have made the following experimental observation on the SIL-3132 <-> SIL-4726 writing speed. I have 5 Seagate 750GB disks, each running at 3.0 Gbps All have write-cache enabled. I can write to 1 disk at 74MB/s Writing to 2 disks simultaneously, the speed drops down to 37MB/s per disk (sum is still 74MB/s) Writing to 3 disks simultaneously, the speed drops down to 25MB/s per disk, etc. Any idea why each disk gets only a fraction of the bandwidth when accessed simultaneously? The port multiplier ought to sustain 300MB/s Thanks, Igor - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
