Comments on: My Amazon EC2 server specs http://jasonmar.com/2009/11/my-server-specs/ Official Blog of Jason Mar Wed, 21 Jul 2010 22:51:30 +0000 hourly 1 By: JMar http://jasonmar.com/2009/11/my-server-specs/comment-page-1/#comment-487 JMar Wed, 21 Apr 2010 05:37:02 +0000 http://www.jasonmar.com/?p=2475#comment-487 Thanks John. This seems to be a problem with my understanding of Amazon's EBS system. If they are indeed allocating me logical drives on one physical drive instead of on a random physical drive chosen from among the thousands that make up the EBS system, which is what I was hoping for, then I guess I might as well have just left everything on one partition then to make the setup a whole lot easier. I never did get around to doing the benchmarking... comparing partitioned vs non-partitioned postgreSQL performance would have answered this question with solid evidence. Thanks John.

The small logical drives are likely to be on the same physical drive or disk channel, and therefore not able to simultaneously operate the drives.
