Hi, I own an Acer Aspire 5 2019 with a Ryzen 5 3500U and an Intel 660p 1TB NVMe SSD.
I noticed a while back, that the SSD performs worse when the laptop is running on battery namely that the sequential reads and writes are capped at ~400MB/s instead of the usual ~1600MB/s. (I obviously tested the drive while plugged in and got the higher numbers. Programs used are CrystalDiskMark and AS SSD Benchmark)
I tried Balanced power mode with the slider on Best performance, High performance mode, disabled power saving modes like ASPM in the advanced power settings...etc no dice.
The BIOS on these cheap Acer laptops is useless, there's nothing useful I can tweak.
I also have a (secondary) 860 EVO installed and the performance cap is not present with SATA SSDs it seems, only the main NVMe (Windows) drive is affected. The 860 EVO performs exactly the same regardless if the lappy is plugged in or not. Funny thing is that the SATA SSD is actually faster on battery than the NVMe one with 550+ MB/s seq.
If anyone has an idea on how to fix this, your help is greatly appreciated.
TL;DR: Intel 660p 1TB NVMe drive on a laptop capped at ~400MB/s seq. speeds. Power saving options disabled and everything.
