All feedback / answers have to be "taken with a grain of salt".
I've had to develop very thick skin because I post a lot of questions on StackOverflow and most of the time they are down-voted, answer incorrectly etc.
Check out this one which the person answered completely wrong and tried to say I was wrong[^].
In the end, I discovered the answer myself and wrote it up for myself.
I actually once posted a question to electronics.stackexchange.com (where the "engineers" tolerate nothing outside of their understanding) about why electrolytic capacitors are rated for higher voltage as the capacitance (measured in farads (uF, pF, etc) goes down.
Not only did they not answer it, they deleted my question entirely and it had taken me a long while to write up the question and I wish I still had that question because it was interesting.
I know that it must also be infinitely more difficult when there is a language difference involved also. Hope you get things worked out.
If you get a chance, check this one out where I answered the question correctly but got down-voted and then the person tried to tell me why my working code was wrong. it was ridiculous.

I will say to your defense:
Most IT people (or you could make it more general, if you like: Most people with a university degree) are very poor at explaining a problem within their field of expertise to someone outside the field. Their advanced knowledge stands in the way.
Even when I ask my co-workers to explain something (I have a Master in Comp.Sci), I may have to guide them through their explanation, telling them 'First, explain how this part works, we'll take the rest afterwards', rather than everything messed up. They use terms that are specific to the stuff they are trying to explain, without explaining the term, and I have to stop them and demand an explanation. When they introduce some 'concept', I ask questions about how this concept differs from this and that older and well known concept. And so on. A good teacher/lecturer would structure his presentation, explain terms, refer to related, known stuff, and adapt the presentation to whatever background the audience has.
Most IT people just opens the sluice gates to let their immense flood of advance knowledge drown you. When the audience doesn't understand a word, the IT expert usually blames the audience  Unfortunately, publishing books is so cheap nowadays that you see the same in a lot of IT books: You senses that the author is really knowledgeable, but the explanations are outright terrible. Sometimes, the better you know the subject area yourself, the more you see how bad the presentation is, how bad the examples are.
Wikipedia is certainly no exception (in many articles, not all): When I try to make sense of them, I often ask myself: Is there a single person in the world who will understand this - and also will look it up in Wikipedia? If it takes a Master to understand the article, then you probably learned enough in your studies that you know all the stuff in the article!
Some textbook authors are excellent. Some academics, even IT people, have an impressing ability to make even complex issues look easy and obvious to a lesser qualified audience. I wish we had a lot more of those. As long as that is not the case, we will have to cope with explanations that requires a lot of work to be deciphered. Sometimes you ask supplementary questions; sometimes the answer gives you the proper keywords for a google search for more understandable explanations. We won't run into those great pedagogics all the time, and have to live with it.

A personal story from way back when:
In my third Uni third year, we had an Electronics course and everyone said if you pass it, it's almost like having the diploma in your pocket. The amazing part was that after every course I would come out convinced I understood everything but when I would read the course again I would realize I don't have a clue. Took me a while to figure out the trick the teacher was using. He would insist on simple things until you realized how obvious they were and just gloss over complicated stuff. Almost like saying "you see 2 plus 2 equals 4 because if you take 2 fingers and 2 fingers that makes 4 fingers... and, by the way, the Laplacian of the electric field in the junction is given by this differential equation...".
He had an impressing ability of masking the the complicated things in deceptive simplicity. Although I passed the course, cannot say I enjoyed it.

I fully believe you story. Maybe that lecturer did not belong in the class of 'excellent' lecturers. Glossing over complexity can be very counter-productive, as you indicate.
However: Grasping the main idea, maybe in a somewhat simplistic way, can be an essential stepping stone. There are exception situations, corner cases, that require special consideration. They can come later. Grasp the main ideas first, even if they do not cover everything.
A good lecturer will make it clear where you might encounter exceptions to the main rules, and those cases will be looked at later. A bad lecturer will use his immense knowledge by rushing on to all the corner cases and exceptions long before the students have had an opportunity to digest the normal case.
Regarding calculus concepts: Lots of students have merely learned 'That's the way we do it!' and have really never truly understood why that's the way to do it. That nature is that way - it is obvious and natural! A good lecturer makes it obvious to you why it simply has to be that way, why the calculus is the way it is.
I remember from my high school years when I got hold of some good books in relativity, and one night realized that the twin paradox simply had to be that way! Anything else would have been completely illogical! Later, I tried to find other textbooks that would explain more advanced topics in relativity in a manner that made it equally obvious. I never found any. But when I was 16-17 yo, I was at the stage where special relativity was an obvious thing to me, even though I was certainly not a calculus wiz kid - not then, and never since.
To me, as a teenager, the twin paradox was self-evident even without advanced differential math. A relativity wiz would probably say that my accept for the twin paradox as something obvious is little worth, it doesn't reflect all the complexity of the calculus. That may be right, but if I can fully accept and and appreciate the twin paradox without all that calculus, I have come a long way compared to a lot of the people around me!
When I ask someone to explain a solution to me, I always ask them to first present an 'intuitive' solution. Your mainline thoughts, void of mathematical details, data types, lambdas, locking mechanisms ... Which principles do you follow in this solution? I consider calculus to be at the coding level. You can say a lot about a system without referring to implementation code. You can say a lot about relativity without going into calculus. And about electrical fields. Just like good system documentation should lead you up to and prepare you for the implementation code, a good lecture on electrical fields or the twin paradox should lead you up to the calculus to take it further. A good one, that is. Not all lectures are good ones.

I think we are going on a tangent here, but hey, it's the Lounge so who cares!

For me the fuse was George Gamow's One, Two, Three ... Infinity. Facts & Speculations of Science[^] when I was 12. Got my mind started on concepts like transcendental numbers, atomic structure, relativity - a smorgasbord of delicious intellectual concepts for a nerdy kid

Funny how our brains can work differently. For some people concepts like music, colors, or relativity for that matter, are absolutely natural. For me they are all learned concepts that I can perceive and understand but I cannot call them natural. With calculus meanwhile, I'm a fish in the water In the end all these differences make the world an interesting place to live. With nerds like me it would be such a boring place.

Firstly, this post comes across very arrogant and I personally think that you are limiting your future assistance from most members that have been supporting you loyally in the past in your numerous questions for help.
You might not think that a post from a person/member is related or is a solution to your question but I can almost ensure you that the person/member that took the time, their own free time at that, to answer your question that you found unsolvable saw it as a solution. For you to then question that free time given to your cause is totally unacceptable and I really think you should re-think your post here and offer some kind of apology.
I for one will ignore your future questions and will rather spend my free time helping someone that will appreciate the effort. I also welcome your down vote on this as it will prove my point.

Just to repeat what others are saying, I also know that if I don't see much effort put into the question... like did the poster try A or B or at least Google something first... I'm less inclined to help. Not trying to saying all replies are perfect, and I do agree I've seen some bad ones. But, it's safe to say certainly not all posters are perfect either.
I find if a poster respects the time of the peeps who answer, enough to do just a little work - even if that means writing more than "where codez?" - it does tend to go better. I think... I hope... maybe?

Well, my honest feelings about this inelegant fellow is that until he "'fesses" up and gives us the true location of his "unseenedness" (by editing his particulars to out his use of the mercan flag) he's just being colorful for the sake of color.

OK folks, you obviously looking for

Why would you need CPU memory to read the disk drive?
From looking at their web page, their drives are all SSDs. Open the device, look at the SSD model, and then google the SSD model to see the interface type. Get an SSD enclosure that matches the SSD interface (SATA/M.2-SATA/M.2-NVMe to USB), and connect that to another PC.

Are you sure that your files are saved in processor memory? I would expect them to be on a rotating or solid state disk.

Your memory module is a Dynamic random-access memory[^] (the second 'D' in DD4). This type of memory doesn't retain anything the moment power goes down.
As others have said, look for somewhere else where your data is stored.

I have a BeeLink also and yeah they are throw aways.
Open the case up and in the bottom is an SSD.
If you can't put it in your computer you can get one of these SSD-to-USB adapters[^] to retrieve the data.

I had my first real encounter with an M.2 disk a number of years ago, when a (non-computer-guy) friend asked med for help with some problems with his disk. I opened the case to see the model of the disk, intending to move it to another computer for testing. There was no disk there! At least none that I could see. I was extremely bewildered. Fortunately, the PC was so new that my friend still had the documentation that came with it, and I could read not only that the disk is an M.2, but also where I could find it on the mainboard. Oh, so that's what an M.2 looks like! I had heard mention of M.2, but had never looked up a picture of one, and would not have recognized it without the documentation.
At that time, I obviously didn't have an alternate M.2 reader, but we fixed the problem anyway - it turned out to not be related to the disk.
If you open the case in search of a SATA flash disk, you may not find it. I am not familiar with the machine referred to, and do not know whether to expect SATA or M.2 disk. From Amazon.com it looks as if some BeeLink models have SATA, others have M.2.
Note to OP: M.2 and SATA type flash disks are completely different animals; they need different kinds of adapters. If you buy an M.2 adapter: Some of them have USB-C connectors only. If you want to read the disk on an old PC lacking C sockets, you should make sure that the adapter has that option. Usually, you can expect significantly higher speed on the C socket.

You open it up it either has an SSD or not. Never heard of the M.2 disks, I'll have to check it. Thanks for the heads up!

Do!
The performance is significantly higher than for SATA disks, especially if your mainboard provides PCIe 4.0 or even better, 5.0 - and the M.2 disk you buy match your PCIe version. But your mainboard must be prepared for it - running an external M.2 through a USB interface is like pearls before swine
Don't be surprised if you motherboard has an M.2 socket! After I discovered that M.2 in my friend's computer, I went home to read the documentation for my old, 2015 vintage PC (i-5820K CPU). Lo and behold, it did have an M.2 socket as well, that I never noticed before! If Wikipedia tells the truth, M.2 was 10 years old last November. So you might be in luck. Having an M.2 system disk, I never notice neither boot up times or application startup times. (Of course it isn't immediate, but it no longer is of any concern.)

As others have pointed out, your link is to standard RAM. Your data's on either an SSD, or an NVME drive. Depending on your specific Beelink model, you could have one or the other (and typically if they ship with an NVME drive, there's also an (empty) slot for an SSD.
Unrelated: I have around half a dozen of these Beelinks; one of them has been upgraded to 64GB of RAM and I use it to lighten the VM hosting load I have on my primary VM host (a traditional full tower). I'm tempted to get another one and also upgrade it to 64GB and retire my full-size tower.
And I agree, their cheapest ones are practically throwaway. I had one die on me (a low-end one) and just moved its drive to another one, and I was immediately back in business.
Prior to that, I went through two Intel NUCs. Both of those are dead - one never turned back on after a major, multi-day power failure, and the other ran way too hot and (I suspect) the CPU just burned out. Both NUCs tended to run hot, and IMO have poor thermal management. That's when I switched over to the Beelinks--I'd never go back to Intel. But then they exited that business, I suspect my experience with them was not unique...
