There are several issues with this page. A few examples:
- DELETE unsupported w/o PK -- this is NOT TRUE, though there may be performance impacts
- DDL statements are problematic -- is this really the case? We have a variety of methods to handle DDL
- I'm not convinced it's wise to recommend 10Gb network and SSDs in all cases. The general statement is true, but it doesn't mean 10Gbps will solve it.
Maybe others... Should probably get Codership's take on these as well.
