Santa was good to me this year and gifted me with a Asus ROG Ally Extreme. It comes with a 512GB 2230 M.2 mini SSD.
Upgrading to a 2280 M.2 without modifying the case and internals will not void the warranty.
I will be adding the following:
Rog Ally Handheld Conversion 2230 to 2280 SSD Hard Drive Expansion Board
WD_BLACK 4TB SN850X NVMe Internal Gaming SSD Solid State Drive - Gen4 PCIe, M.2 2280, Up to 7,300 MB/s - WDS400T2X0E
M.2 Heatsink Copper, m2 pcie NVMe Laptop PS5 Heatsink Copper,with Silicone Thermal Pad, for M.2 2280 SSD Laptop
There are many videos and Reddits available detailing this process with as many recommendations, and, of course, opinions regarding power draw and temperature concerns.
Current idle temps are running at 43C average. I have not stressed it with games via Turbo mode as I did not want to install anything only to have to do so again. I have chosen to go the route of system restore via BIOS rather than cloning the drive.
More to follow...
