Toshiba XG6 review: The first SSD with 96-layer 3D-NAND!

Is Toshiba now competitive with Samsung and WD?


Power consumption

We test the power consumption of PCI-Express SSDs on our desktop test system, where we can measure the power consumption using a riser card. We do this with both a 4k random write and a 1MB sequential write workload - for a good idle test our riser card is unfortunately not accurate enough.

The consumption of 2 watts in the random write-test is very low, which makes it one of the most economical NVMe SSDs. This was also a strength of the WD Black; other low-consumption SSDs are often much slower. Sequential writing increases consumption to 4.8 watts, but that's still enough to stay in the upper half of the chart and to stay well ahead of the Samsung SSD.
