Hi, I assume you're talking about the MSA60? We have several of those installed and haven't seen any bottle necks there. Even the fastest SATA drives fall short of the 150MB/sec max SATA I throughput. And if you could push the 1.5Gb/sec on the SATA side, then the SAS side with a 4x port (4x3Gb/sec) would become your bottleneck. Peter. On Tuesday 02 September 2008 11:23:00 am Joseph L.
