Somewhere around 1.5GB/s. I went into a bit more detail as to why over here, if you're curious.
Thats good to know.

A claimed 25mW power consumption actually turns out to be 225mW with testing equipment and that is high compared with other NVMe drives. The idle power consumption is an important stat but peak power draw is unknown  - no information is provided about the state 0, 1 or 2 power consumption unless someone has one to hand?

I have one on my desk waiting for the Pinebook Pro to arrive. I'm in the first batch AFAIK, so I'll have details (hopefully) soon. If you know of a way to test power consumption in advance, I'm happy to give it a shot (even with a small risk of burning the drive); I've got your usual hobby electronics lab available, along with zero fear soldering surface mount.

Massdrop conveniently put up an SX8200 Pro, so I got the 256G version.  I figure that will be plenty fast enough.  I know it's going to be throttled by the board ad such, but should still be speedy.  I don't have the equipment to measure power draw from the drive itself, but after using it for a bit I can at least provide "gut feelings" regarding how it affects battery life, heat etc.

It's $50 on Amazon.  Oddly, it's less expensive than the SX6000 Lite.

Almost all of these drives will be faster than the 1.5GB/s of the PBP, but that  limit also reduces heat and power consumption.

Hm? According to that Tomshardware review, the following power consumption was measured:
Idle: 0.01 W
Active Idle: 0.552 W
Load: 1.93 W

Still that is strictly better than the Intel 660p.

HAHAHAHAHA so it is.  WELP.  Guess I overpaid.  Oh well.  That's what I deserve for not shopping around.

In any case, I agree.  Since it will be throttled, the heat and power consumption should be less of an issue as well.  And, if I eventually decide I want to use the drive for something else...I still have a bangin' good drive.

- up to 2,200/2,000MB/s
- 180,000/200,000 IOPS

I haven't found better information about its power consumption.  Although, since the 250GB sells for only around $40, I'm strongly considering it.

The Kingston 250GB NVME M.2 Internal SSD SA2000M8 250G is listed as 2GB/s read and 1.1GB/s write.

There is now a Kingston A2000 review on Dutch website Hardware Info, including power consumption figures: https://nl.hardware.info/artikel/9529/ki...rijsbreker

The Kingston A2000 performs quite admirably for the price, beating the Intel 660p in the majority of tests.
Power consumption during 4K random write is 2.38 W vs. 660p 2.5 W.
During 1 MB sequential write it is 4.89 W vs. 660p 4.43 W.
Unfortunately no figures about idle power draw.

That looks really good, thank you. 100 dollars at Amazon for 1TB.

Spec list in english can be found here:
https://www.guru3d.com/news-story/kingst...e-ssd.html

FTA:
  • Power Consumption: .0032W Idle / .08W Avg / 1.7W (MAX) Read / 4.5W (MAX) Write
I wasn't seriously considering 1TB, but I am now. I can justify it at that cost.
