I am wondering what SSDs are recommended for laptop use.
Power consumption in idle would be a big factor an addition to performance.

On desktops, idle power consumption makes little difference.
Phison E12 based drivers or SM2262EN are top performers and decently priced, but seems than Phison E12 is more hungry.
The higher power consumption would surely make a difference in battery life in a laptop.

Recommendations?
Maybe WD SN550 or SN750?

Any.

'Power consumption in idle'

SSDs have idle states and the largest consumer of power most of your usage will be your display brightness. If you are interested in better battery life, keep the battery in good condition and if it's old, just buy a new battery if you can.

Intel/Micron/Samsung drives are usually at the top. With Samsung, don't install the Samsung drivers if you want the best battery life.

@razel If the SSDs don't go properly into their lower power states(or prevent rest from doing so), it can impact battery life significantly. The difference between the Samsung driver and the default driver is 30%(nearly 3.5W!), and that's using a power hungry 6700HQ CPU with 17.3-inch display and a discrete GPU. Imagine that on a ultrabook!

In our retired test using a Lenovo W530 mobile workstation, the best result we achieved was 676 minutes; our worst result was 345 minutes. The variable: simply changing the storage media!

Don't go with no-name brand Chinese SSDs because it'll have shoddy firmware which is fine on a desktop but will either prevent the SSD from reaching lower power idle using few W of power by itself or prevent the other part of the system such as the CPU from reaching the lower state.

Testing on WD SN750: https://www.tweaktown.com/reviews/8874/western-digital-black-sn750-ssd-review/index3.html

The SN750 is near the top in power testing, but bottom of the charts in battery life.

When looking for reviews, try to find those that measure battery life, not power consumption. They are not the same.

Thank you very much!
I had a hard time finding reviews that highlighted battery life. The article by tweaktown is perfect!

Appreciate it
