That power consumption seems shockingly low, so who knows how accurate it really is, but one would *think* that Intel knows how to measure it properly.

Thanks, it is only available in 2TB, 1TB, and 512GB.

Here is more information about the WD Blue SN500 which has a different edge-connector:

Here is more information about the WD Black SN750 NVMe SSD:

It looks like most manufacturers are using this https://bapco.com/products/mobilemark-2014/ or this https://bapco.com/products/mobilemark-2018/ which only runs on Windows.  If there is a similar testing application that runs under Linux on the PBP, that might help early SSD adopters share useful information.

Ill keep my eye on the price for Intel® SSD 660p @ $36 USD for 128 and $54 USD for 256 not bad for a give it a shot hardware.

I was thinking something similar.  In order to have better comparisons, the drives should be the same size.  I propose 256GB.  That is two times the size of the eMMC in this first batch, and four times the size of the eMMC in later batches.  256GB should be enough space for most purposes.  Also, smaller drives use less power than larger drives.  (Participants who need to carry around massive files could take advantage of USB Type-C and use a portable external drive such as the Samsung T5.)

I'm still looking to see if there is a Linux application similar to MobileMark.  If anyone knows, please post about it here.

Also, still waiting to get better physical specifications, such as maximum height.  I am not a mechanical engineer.  Although I'm thinking that the PBP doesn't have a fan and air is an insulator, so the SSD would use something such as a silicone pad to heatsink it.  Then again, I could be wrong about that.

The 512GB version is currently selling for $49 USD.

This is the Supported Power States shown with smartctl:

No need to put a thermocouple on this one. nvme smart-log provides the sensor temperature of the drive.

If anyone knows of a source of that information it would be greatly appreciated.  Considering how many people put them in portable devices that have limited power and battery life, I'm surprised that such information is not readily available.
