Can you do a speed test of your zpool?

dd if=/dev/null of=<mount-point>/test.file bs=1G count=10 status=progress

I use Standard Notes

I upgraded. The new screen was worth it to me. But I’m amazed about how quiet it is. With the old one I routinely reduced the wattage to silence the fans but I didn’t feel the need to do it with new one. The battery life increase is nice but was rarely a problem for me.

I sold my old one to offset the cost.

My consideration was that the Steam Deck is my only gaming rig and I use it daily. It was worth the upgrade. If I would use it less like my Nintendo Switch I wouldn’t. My Switch is still the old LCD model.

Did you try S3 sleep?
