RE: [CentOS] SAS/SATA DAS

I assume you're talking about the MSA60?

Yup

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.

Good to know! I think I am actually going to get an MSA50 and go SAS. The cheaper enclosure affords me the chance to get good drives and if the need to expand comes I will just get another, it can be cascaded 1+1 and there are two ports on a P800 so I can hook up 4 of the things.
