nvme drive disappears after about an hour of uptime

Yep, even fully powering off, this drive retains those values.

Good to know! The main reason I'm using USB-C over barrel power is that I don't have a USB-A 15W adapter; the 15W adapter I have is a USB-C to USB-C, and the outlet provides only 2.4A max on the USB-A port, so right now USB-C is going to give me more power. Good to know I should invest in a new adapter, though. Do you know what the specification for the barrel port is? I was under the assumption that both were rated for 5V 3A max.

I did have some issues today while plugged into USB-C, similar to what is described in this thread, where my screen appeared unresponsive, and subsequent attempts to boot resulted in the same power LED symptoms as the video. After leaving it to cool for an hour, same symptoms. I then charged it for an hour or two, and all was well. I'm guessing I either overheated it and the battery drained too quickly; was fine an hour beforehand, but had it in a less cooling-friendly spot.

Until the above happened, I again ran a restic restore overnight, this time with 5500 max exlat set. The result was still no disappearing NVMe, so I think for this drive, it's just APST with the PS 4 that's the issue; PS 3 seems to work.

Going to try leaving my PBP on overnight with Gen 1 and no I/O this time, to see if the drive disappears if it goes down to idle PS 3 without heavy load. If that works fine, I'll give Gen 2 speeds a shot.
