Brian, I'll agree with this to some extent if all you want to do is write a file, read and update it a few times, and then delete it.
However when it comes to Business Continuance, Interoperability, Virtualization, and other not so traditional features I don't agree that one can just go out and by 'NO-NAME' generic mainframe DASD, plug it in and expect it to automatically meet all your needs. This where each vendor has strengths and weaknesses that may or may not be relevant to you companies not-so-traditional DASD requirements. Old Sharks are very fast? I have some difficulty with that one. A USP-V doing nearly 400,000 SSCH/sec with 0.7ms response time is what I call fast, and that's without zHPF.
