I just got a new laptop today and when I saw the ssd it blew my mind. Most of my old drives are like the second from left and it's what I think of as a normal drive, buying a standard ssd still feels small to me. But look at that tiny thing to the right! It's the size of a postage stamp!
Assuming I managed to find the right specs (it is a Microscience hh-1050): The monster on the far left is from 1990, holds 40mb, read/write of 0.625mb/s, and weighs almost exactly 2kg. The baby on the far right I got in the mail today, holds 1tb, read/write of 5150mb/s, and weighs about 2.85 grams.
So we're looking at 25,000 times more storage, 8,240 times faster, and 1/700th the weight! And the one on the right is just 1tb, they make one that same model but 2tb. I can barely believe it exists even though I'm literally holding it in my hands.
It really is amazing, and just popping an m.2 into a motherboard directly is just so... easy. And I think Gen5s are what, 2.5x faster than what you're showing here?
The screw situation is finicky. It's a weird mix between you're supposed to have screws from your case/motherboard or sometimes the drive comes with one. But if you move stuff and drop the tiny tiny screw it's a hassle. Every motherboard should just have the little tab you just turn to keep it in place.
Plus the newer gen fast drives get hot so they need a heatsink. The fastest maybe need heatsink plus airflow. So then you need an extra fan if you don't have enough airflow which is easy because it's flush against the motherboard and sometimes blocked by the GPU.
