Note: In this test, we use the Lenovo W530 Mobile Workstation and a SuperSpeed S301 SLC 128GB SSD to move a 15GB block of data to and from the target drive. This is part of our real-world test regiment. Roughly 45GB of data resides on the target drive before the '15GB Block' is transferred. The 15GB Block is the same data we built for the Data on Disk Testing and is a mix of compressible and incompressible data.




On the Disk Busy Time chart on the previous page we observed the 850 Pro taking longer to complete tasks than the Extreme PRO 960GB. We didn't talk about it on that page for a reason, we wanted to tie disk busy time into notebook battery life.


The faster a drive completes the read and write operation, the faster it can fall back into a lower sleep state. While Windows has sleep state, drives have onboard sleep states as well .The Samsung 850 Pro uses less power than the Extreme PRO while in use, it takes longer to compete IO tasks and this means the time at a lower sleep state is reduced. That's why the Extreme PRO delivers longer battery life in this test.


That isn't the end of the power story though because the notebook used for the test uses an Ivy Bridge processor and chipset. That means we can't test DEVSLP, an area that the 850 Pro does very well in. We're working on securing a new platform now that takes advantage of the lowest sleep state capabilities.
