I just got mine last week and have been playing it non stop. I had so many games that I wanted to play, but hate playing on a desktop since it’s more enjoyable to play when I’m with my wife and her switch or as she watches tv.
Such a big backlog.
I got the 64gb version and plan to upgrade the ssd at some point.
As someone who ordered the 64GB version, they never should have sold that thing. The entire thing gets filled with shader cache so fast. Not to mention any software you actually want to run on the device like EmuDeck, Chryoutils, Heroic Launcher, etc. etc.
How easy are we talking? I have literally 0 experience doing anything like that. I do have basic tech knowledge, but I haven't customized any sort of computer since the early 2000's (and even then we're talking simply installing a new graphics card).
I want a steam deck, but I want more, and faster storage.
It's very easy if you've done anything like this before. I would definitely follow a full guide, but the basic process is that you have to remove the microSD, take a few tiny screws out, pop the back open, unplug the battery, take a few more screws out, remove the heat shield, swap the SSD, and then put it back together.
After that you need to reinstall steamOS on the new drive, so you need a way to plug a USB drive into the deck (a dock, type-c adapter, or a type c USB drive). You can install the steamOS recovery software to it following the online instructions, boot the deck into bios with the USB drive plugged in, pick to boot off the USB drive, and then hit reinstall steamOS once the recovery desktop loads up.
Only part where I've seen people have problems is by stripping out the screws on the back of the deck. You have to make sure you are using an appropriately sized screw driver and that you have it fully inserted into the screw before turning. This usually isn't hard to do, but if you strip a screw it can be hard to remove it.
On my desktop, I was installing almost everything to a mechanical drive. At one point, I was using my NAS as a place to play games. So the SD card is perfectly fast.
I upgraded mine before I ever even turned it on. Now I just wish I'd gone with the 1tb instead of 512gb. I did get a hub, that allows me to connect external drive enclosures. A recent update just enabled auto-mounting external drives, which is nice.
