Power Consumption: Idle And PCMark 7
Idle Power Consumption
Because SSDs are so fast, they sit idle most of the time. In almost our almost 30-minute virus scan, the SSD is only busy for 281 seconds. As a result, idle power consumption is the most important figure to consider in a desktop environment.
We've already seen Samsung's architecture fare particularly well in idle power measurements, despite its beefy triple-core ARM-based controller. In comparison, the Vector doesn't do quite as well, suggesting it might not be as suitable in a mobile environment. Even though it delivers performance that comes close to Samsung's 512 GB 840 Pro, OCZ's Vector requires 2.6x as much power at idle.
PCMark 7 Power Consumption
Again, even as the Vector serves up performance that approaches Samsung's flagship, it requires ~28% more power under load to do so. Both drives dip in under the 1 W mark, so the absolute difference is still small compared to a CPU or discrete graphics processor. However, it's still clear that Samsung has an advantage in efficiency, especially if you're looking for an enthusiast-oriented SSD for your notebook.
If you shift the comparison to SandForce-based SSDs, the Vector is on par with OCZ's older Agility 3 drives, edging out the slightly more power-hungry Vertex 3 and SSD 520.
