Power Measuring Kingston A400 480 and Samsung MZ7LN128

In this session I measured a Kingston A400 480 which is much better than the smaller sizes. It's as great as the Patriot Burst 480: Very fast and very low power consumption. Additionally an old (used) Samsung 128 was measured.

Method

Measuring environment is explained in power measuring ADATA SU800. The speed as logged and calculated in latest measurements was simply done by taking the time for reading and writing the whole SSD in relation to its size.
