Unlike in past tests, this time around we decided to go with the h2bench2 from c’t magazine, since the results do not vary as widely. For that reason, the results of this test cannot be compared with those in previous articles without qualification.
We tweaked the test parameters for the temperature measurements as well in order to more accurately simulate real-life conditions. In concrete terms, that means the I/O meter ran for about two hours, subjecting the drive to a fair amount of strain. Only then did we read the temperature using an infrared measuring device ; the highest recorded value is reflected in our diagram.
