Why is the SN750/SN850 the default SSD, given it has relatively high power consumption[1] and separately is there any reason to believe that building a DIY version with a different SSD wouldn't work?
We see folks in the community using a range of different SSDs, but SN750/SN770/SN850 are what we have done the most validation on. We see good perf/watt on the WDC drives. It's unclear why Tom's Hardware was seeing poor idle power with power saving modes on.
