Hi,
i have quickly skimmed through this thread (quite long). I have a mid 2015 macbook pro 15". I wanted to upgrade my ssd to 1Tb or 2Tb. I had my eyes on the samsung evo 960 and 970 models. The think that strikes me the most is that i have read in this tread that these ssd are power hungry and the overall battery life can go from 9 hours to 6 hours (30% less).
Is this true in the case of my mid 2015 macbook ? Can anyone confirm this ? If this is true is there any other ssd that does not affect the battery life significantly ?
I often work while travelling and I would like to keep doing so.
Thank you

Hello, finally I just installed 970 evo 2TB on my macbook pro mid 2015:
- upgraded to 10.13.6
- cloned system on external ssd with ccc
- open mbp, unplug battery
- replaced ssd with sintech green adapter and new drive (I did no magician upgrade)
- reassembled
- booted from external ssd
- formatted new drive
- cloned back my system to new drive
- booted from new drive and set it as new boot volume
No issues at all, ssd recognized and formatted apfs without problems.
I did a "normal use test" before and noted temperatures (ssd, cpu), battery % and battery lasting time. I need to do the test with the new drive but because I used Hardware Monitor 5.55 it don't recognize the new ssd sensors*.
Speed: before r1956/w1080, now r2240/w2520**.
I have 2 questions:
* I'm searching a ssd thermal sensor app who work with the new ssd. I found maybe iStat menu but I will not install an app so rich of features only for the ssd temperature (I try to keep my system "cleaner" as possible). Someone can suggest a light app only for monitor ssd temperature? Then I will post the comparison.
** Yes, it is what Black Magic Speed test show: write speed is bigger. Is this normal? In system profile I see x4 and 8.0 GT/s for the connection. Maybe a software bug...
