I'm happy to answer any questions around this! We've been working on this since update since we launched the product last year, so we're excited to be able to share it today.
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.
