Hi, does anyone have any concrete performance benchmark numbers for disks attached to SATA port multipliers? I'm wondering if there is any overhead incurred by the switching/multiplexing of the SATA protocols. If I have a SATA 6 Gbit/s controller with a port multiplier and I attach 5 disks which are each capable of 120 MByte/s sustained read, and I read from them all simultaneously, will my controller be able to see 600 MByte/s, or will there be a performance hit at the multiplier?
Thanks.
Thanks.
