I've had the same arguments, even when vendors come in and use their own tools to gather performance stats. Managers argue that the vendors skew their results to sell more disk. That's why I have worked hard on understanding who, what, where, when and how to capture and analyze performance statistics on my own (and write about it here). It's hard to argue with the raw data.... 15k disks are not always the answer, but don't go buying a solution without asking questions and preparing with some good data!

I argued with my now ex-boss about why 20 7200 speed disks were worse then 20 15k or even 10k disks.. and he still said ahh they wont see any issues.. some people are just dumb.. Now had the SAN solution been for file storage I would have said no problem with using 7200K speed disks.. But this was for VMs, which included Exchange, Sql and oracle! Still my boss insisted it wouldn't matter..
