The latest USB standard (3.2 Gen 2) goes as high as 10 Gb/second. The actual data rate is lower because of the protocol overhead. I doubt that the flash memory used in flash drives can keep up with that. It should be able to keep up with USB 2.0 (480 Mb/second).
OTOH, even SATA SSD drives can reach speeds of 4.5 Gb/second of data. This is close to the SATA III speed (6 Gb/second), if you allow for the overhead. A PCIe or NVMe drive is even faster.

You've thrown me by saying "(RAM?)". While at an electronic level, RAM and Flash might use the same or similar technology (I don't enough to say yes or no) SSD is definitely not "RAM" which is very specifically RANDOM ACCESS memory. As such RAM is directly accessible at a much more granular level than an SSD is (normally) accessed at. RAM doesn't have a "file system" mapped onto it, and yet (with some exceptions such as when formatting or writing boot blocks - perhaps) an SSD is normally accessed via a filing system, reading/writing "blocks" of data within a specific file. Clearly within the SSD itself, each byte is directly accessible but from an external viewpoint, it's not.
I'm probably not quite right on some of the implementation details but in general, the term "SSD" is used to refer to a solid-state device giving access to data via a file system of some sort, whilst RAM is directly addressible. I think that's an important enough distinction to warrant removing any reference to RAM from the SSD / Flash discussion...

Presumably you are asking for a technical answer.
I would surprise me if the answer is in fact technical versus nothing more than marketing.

Stanford Lecture: Dr. Don Knuth - Dancing Cells (2023) - YouTube
I haven't watched it yet, so I can't comment. Apparently, Stanford has made many of the Christmas lectures available, so there's plenty of watching, for those so inclined.

I really wanted to watch it but age has crept up on him and he's so hard to follow, I couldn't watch but a few minutes.
I have two of his books and they are incredible.
What a brilliant human being.

Thanks!  I've heard much about Donald Knuth through the years, but somehow just never got one of his books. Seeing the examples, and learning of the dancing links/cells, I will be getting one of his books in the near future.

If you are interested in algorithms, treat yourself to The Art of Computer Programming, 3rd Edition. To date, there are 5 volumes and Knuth plans to add more as long as he holds out. They aren't cheap, but they will tell you more than you ever wanted to know about algorithms.

A gentler and more student-friendly book on Algorithms is written by his doctoral student and also a noted Professor himself, Robert Sedgewick. This is one of my favourites.

I have both, but I prefer Knuth for its comprehensiveness. Also, my lecturer in Data Structures and Algorithms (many moons ago) used Knuth's style when describing algorithms, so I'm used to it.

If the Muppets were still being produced, they could have a Cats in Space to go with their Pigs in Space sketches.

They're Americans, who have a rather puritan view of such matters (at least in public...)

Unfortunately for Americans, that's a totally fair assessment.
And yet, do you really want our first successful contact with an alien species to be humans mid-coitus? We look ridiculous. 
Also I want to try to explain underpants to aliens. "Small secret pants we wear under our regular pants"

In Britain we only wear a single pair of pants, and they go under our trousers.

Unless you wear a kilt of course.

With the exceptions of the dress uniforms of certain Scottish regiments, and certain formal occasions, I doubt that kilts are as popular, even in Scotland, as they used to be.

Be that as it may, perhaps a man named MacCutchan is more likely to than you and I.

That's because they have more muscles than brains.

Well ... I think he masturbates
No, seriously. If I have a furry blanket, he gets on my lap and stands with all four paws together and his back seriously arched, and "puddles" away like crazy with his ears back and a very ... focussed ... look on his face. This lasts a while and he's clearly enjoying it. He then hops off and licks his gentlemans vegetables.
Yes, he's been neutered. Still does it every chance he gets.

I didn't realize there was a cat on the Psyche probe. That explains why it's so big.

If they can fit one, surely they can stuff more in there.
