I have had a lot of comments, mostly constructive, on some of posts about performance and the EDL 4000 3D. (The translation of that product name, by the way, is the EMC Disk Library 4000 with deduplication.) W. Curtis Preston has been one of the most vocal critics, and while I think he is dead wrong--nothing personal, Curtis, that is just my opinion of your opinion--I don't think his comments are so trivial that I am going to dismiss them out of hand. I also suspect that they are roughly congruent with the initial reaction some users might have to the device.
So I wanted to take the opportunity to address some of these comments in a more structured fashion than just the back-and-forth in the comments section. Giving Mr. Preston his due, I will quote him directly and then respond to the objections.
