I can't see a benchmark coming out that everybody is happy with. No matter what benchmark it is some people will feel it favours small writes/reads more than "real" use, and some people will feel it doesn't favour them enough. Some people will feel the drive should be asked to do several things at once, other people may feel this doesn't represent real use.

A drives performance will vary greatly depending on what it's asked to do, and since nobody has really come up with an accepted formula of what the drives will actually be doing in real usage then it's very difficult for a benchmark to come out which will show actual real performance.

OS boot times for example mean nothing to me. I boot my PC up once a week. But other people may boot up twice a day and use the device for half an hour. Some people might be concerned about how long a virus scan takes. Other people might have it scheduled to run at 5am and aren't bothered.
