grab a usb enclosure off of amazon like from sabrent or something so you can plug it via usb.

your pc tower looks old and does not have any m.2 connectors where you can plug this ssd in.
I checked the service manual for the Latitude e6530 and the motherboard does not have the necessary slot to accommodate an M.2 drive, which isn't surprising given the computer's age.
You won't be able to install the M.2 into the e6530 directly, but you should be able to run the drive in an external M.2 enclosure attaching through a USB port.
If you do try to run the drive in an external enclosure, be careful to use the USB 3 port on the left side rather than the USB 2 port on the right side. USB 2 won't provide sufficient throughput.
If you want to replace your existing hard drive, you'll need to use a 2.5" SATA SSD.
There are two sets of things to consider: 1) the general "can it work"/sort of round peg into round hole. 2) the AW complications, aka round peg into irregular enneatriacontagon hole.
Faster RAM is going to be all sorts of tricky in general. The most common "just drop it in and 99% of the time it just works" is 6000cl30. That is with Zen4 CPUs. The 6800H? is Zen3+, so older design. that is going struggle to run faster memory, etc. Also the question of actual SODIMM kits: laptops tend to use low spec memory. Also general issues with DDR5, its still new, it still has some bugs getting worked out, etc. DDR4 is 7-8+ years old, DDR5 is maybe 2.
The AW complication: AW is really, really picky when it comes to memory. You have some reports of "if its no Dell RAM, its not working" to "just toss in whatever" with the common advice of "consult the sacred texts/bones before installing". And that is for desktops, laptops are worse.
So faster is probably not an option. Bigger should be just fine. Its more going to be a case of hoping one of the 4 options works.
For the SSD, bigger is worth it faster is not. Short version, outside of proper high end builds gen3 will be less than half a second slower than gen4 in the best case. If the gen4 drive is cheaper, sure get that. But a good gen3 drive will be just as good. What sort of capacity are you looking at? This is a rock solid 2TB drive. There has been a lot of shady stuff going on with SSDs and component swapping so if you want more than 2TB ummm... WD seems to be
on the good side of things and Crucial has there own fabs for at least some parts the issue should be at least mitigated.
It looks like you only have a single internal drive. A minor, but very solvable issue. You are going to need an m.2 to USB enclosure, something like this will work. Probably worth spending a little more on a good one, the performance to USB is going to stink so in theory a better drive will have a better controller to help keep the speeds from crashing too hard. You may also need a USB drive to run a second OS off of just in case.
Put your new drive in the enclosure (it will end up being a portable drive in the end), plug that in and make sure it shows up. Next your going to need some cloning software. Macrium Reflect is often mentioned, Clonezilla is no where as flashy but its sort of hard to beat open source, at least in price.
Jumping ahead, you should have the current drive cloned onto the new drive, swap the new drive in to make sure it works and assuming it works, your done. Take the old drive, put it in the enclosure and you have either a backup or you can wipe the drive and have portable storage.
Turned out the SSK drive was the issue, only with the steam deck.
I bought a [Sabrent](https://www.amazon.com/gp/product/B08RVC6F9Y/ref=ppx\_yo\_dt\_b\_asin\_title\_o00\_s00?ie=UTF8&psc=1) one, and it works fine.

Thanks, the link you gave appears to be RTL 9210 instead of the RTL 9210b.
I found this one https://smile.amazon.com/gp/product/B08DCLPYGK/
and this one https://smile.amazon.com/gp/product/B08RVC6F9Y/
The bigger issue is adapter. I've used the wd blue NVME with this adapter and have had no problems. Anything with the same controller should be fine.
A quality NVMe enclosure and your own drive.

Or spend half as much on spinning rust that's 50X slower and guaranteed to fail immediately if you drop it or naturally in three years.
Crucial P3 4TB NVMe ssd is available on amazon US for $199.99 & is fine as a secondary NVMe/storage drive. Crucial 4TB MX500 sata ssd is available for $216. You can use these NVMe drives in enclosures like these:

Similarly for sata ssd:

Only minor issue with these enclosures is lack of ventilation so not so good heat dissipation but if using in a cold environment or just using it while taking the cover off then these work fine.
You can use any software to take backup but if you want to take "drive image" backup which incl entire partition/OS drive then imaging software are required else if you just want backup of folders & files then any copy/sync software will do the job but keep in mind that by default many copy softwares/windows default copy doesn't preserve time stamps of files & folders while copying across drives so use a software that allow preserving time stamps of files & folders.
There's an M2 SATA SSD (256GB) in the M2 slot. I don't see any 2.5" SATA HDD in there. Also an occupied M2 slot for a second SSD.
You want to take out the SATA SSD (remove the one screw, then it pulls right out) It's the size of a stick of gum, and has the white sticker on it that says 256GB.
