You completely misinterpreted (and misquoted) me on that one. I wasn't implying that they should hire a consultant for this kind of thing, but they should at least have bothered to read anything about the methodology used by SSD reviewers or the industry standard storage testing methodology freely published by organizations like SNIA. It's clear the BBC guys didn't even spend an afternoon trying to read up on how to evaluate SSD performance; they just jumped in and started re-inventing the wheel, hitting all the foreseeable problems along the way. It looks like they now have a clue and have learned a lot from the process, but this is not how you should handle this kind of upgrade.
