0 fill is a worthless benchmark statistic unless you happen to be in marketing and would like to completely misrepresent the performance of your product.

The only benefit of running a 0 fill benchmark is that it enables an end user to mimic how marketing people came up with misleading performance statistics.

SNIA is the only benchmark that properly tests a SSD’s performance.

With SNIA, a random data stream is a mandatory part of the test, which makes a lot of sense. SNIA also allows additional tests with non-random data streams (which must be reported by the tester), but the random stream is still mandatory.

Clearly, random data streams should be the default for any test. If someone is testing an SSD that has the ability to do compression, they may want to add some non-random data streams (and report in detail what they used), but they should ALWAYS include a random data stream.

SNIA got this exactly right with their SSS enterprise AND consumer ("client") tests -- a random data stream is mandatory for both enterprise AND consumer tests.
