Thanks for the review. We should see more reviews comparing SSD and HDD battery life, but reviewers just ASSUME SSDs will be better at it.

Implementation details matter, and you can only see that by testing it.

Though I'm not a fan of using the Y700 for the test. The HQ chips do not have anywhere near the power management capability of the U chips. To be clear, its just about U series having lower TDP, but much lower idle as a platform.

I'm not sure whether such tests can be done reliably on a U platform as there may be drive specific optimizations done, and make the numbers irrelevant for actual products. But if its possible, U platforms would show greater differences in battery life between drives.

You have to remember that we still have to meet deadlines (NDAs) with the reviews. I would need even more systems if testing on a U series processor or other system that gives users 10+ hours of battery life. It's still difficult to find systems that can use both M.2 NVMe and 2.5" SATA. At the end of the year I'll see what's available and most likely move away from a gaming platform. I expect these systems to stay in use until early 2019.

I've been approached by a lot of folks regarding whether or not the addition of an SSD storage can and will improve battery life or the opposite. This article does bring some things into light! Thanks!

I must also point out though that there are some among the community who are working with both a mechanical HDD and an SSD both in the 2.5" form factor so it'd be a nice write up to see if both drives running in the same laptop/mobile computing device takes a bigger hit in battery backup/performance.

To clear up, folks use an SSD caddy that does into a 9.5mm/12.7mm ODD slot on a laptop to re-purpose the SATA port for use with either an HDD or an SSD.

Or maybe, like my MSI laptop, shipped with an NVMe SDD and 2.5" HDD.
I switched the HDD with the pretty-good scoring MX300 (thanks for confirming my good choice).
I also tried to replace the Toshiba NVMe with a M.2 SATA SM951 as the Toshiba would make a noticeable hotspot on the case. But it seems there are some mechanical issue with m.2 sata as flexing the case nearby would freeze the drive and touchpad until reboot.
