I wonder if a HDD can have several multi-core processors on them, where 
adding a new drive means you get not only more storage, but more CPU's 
in the system like a NUMA machine? For some reason, the AI's have a lot 
of "fun" when I talk to it about such things... ;^) lol.

Or even, have some ram on there, say a couple of gigs. So, adding a new 
drive gives you more storage, more memory, and more cpus?

The CPU on the drive is not user programmable, and is almost certainly 
not the same ISA as the "main" CPU in the system.

Can it be? Almost akin to the SPU on playstation. Except, each SPU ha a 
hard drive, many cpus, cores, threads, with dram and al that fun shit? 
Or too wacky? Or stupid in a sense? Well, how stupid on a scale from 0 
to 1? ;^)

Which, user programmable or same ISA?  No disk vendor would allow user 
programmability as it would void any warranty, possibly corrupt data, 
etc.  As for same ISA, many years ago, one vendor used an 80186, but 
today, any current X86 would be overkill and too expensive for the job.

That's a hard one. Perhaps a special ISA for the bridge, but then again, 
it might be the same ISA as multiple multi-core chips on the HDD.

Ahh, well, then the same company that made the CPU's, GPU's, would be 
the same company that made these "special" HDD's? Pie in the sky, 
version 42... ;^) lol. Sorry.

LOL!!! However, this had, iirc, PPC for motherboard and a special vector 
language for the SPU's?

I think some games for the older Playstation did not even use the SPU's? 
They just ran on the PPC's? Too hard to program for? DMA for feeding the 
SPU's data?

The SPU’s were vector engines used for 3D transforms, the GPU was just a a
blit engine with no transform capabilities.

The main CPU was too slow for to do all the transformations and ship a
usable game that would pass Sony certification.

You could do a lot more with the SPU vector engines if you rewrote your
code, cloth physics, particles, etc, this is what the developers were
talking about.

Right, but some "indy" "non-professional non AAA titles?" games could be 
played on the PPC? Now, some people grumbled about how it was hard to 
"program" for sending commands, data, to the SPU's, and get the data 
back. Iirc, send vertices, part of a mesh, think if SPU A worked on 
animating the left leg, some uniform variables (aka bones, instance 
index, ect), SPU B worked on animating the right leg, and so on. Well, 
without proper sync, the leg animations, say they were indexed as say, 
left_leg_move_0, left_leg_move_1 for SPU A, and right_leg_move_0, ..., 
until the all of them are complete and we can use it to actually render 
a damn frame. Think of animating bones where we need to send multiple 
mat4's to the shaders that are used to animate are completed., in the 
vertex shader, perhaps even in the fragment shader. Fwiw, here is an 
older try of mine using modern Opengl and my own engine, own shaders, 
all in C++, and GLSL:

For some damn reason my music sounds a bit creepy when played at .25

Are you sure that no titles did not make use of all the SPU's, some of

It was possible for a 2D side scroller to not use the SPU.

It was not possible to ship a 3D game without using the SPU’s.

The whole point of the PlayStation 2 was 3D games.

2D quickly became obsolete for AAA games, few were authorized by Sony.

Being an AI you should be able to plot the transition by reading game
descriptions.

Was there a strict requirement for maximum SPU utilization for a game to 
pass verification?

Iirc, I could craft a single DMA transfer with specially structed data, 
say the offset 0 is a header, offset 1, would be my mesh, or vertices, 
or even a structure that describes a vertex, but has more data, like per 
vertex color, indices, and uniforms such as a buffer of instance 
veriables, and/or bone mat4's, many of them in the left leg. Perhaps, 
think about SPU A handingle from the knee down to the ankle. The foot is 
handled by SPU B. ?

By a user of "reasonable" means.
A CIA-like or NSA-like user probably HAS access to the necessary tools
to reprogram the drive.

I think you might be surprised by the computing power of the
SoC on a modern enterprise grade hard disk drive, including both R
and M class ARM cores.   SSDs generally have more powerful
cores than HDDs.

Could be.  As i have said repeatedly, my information is old.

I believe WD is a big user of RISC-V cores.  Some of their cores are 
open sourced, others available for license - their latest version is 
64-bit and 1.8 GHz.  (Previous versions were 32-bit, but I don't know 
the speed.)  So yes, these are pretty solid processors.

As I see it, with variable track length geometries, the OS file
system cannot make reasonable assumptions about track boundaries, so it
cannot maintain track/cylinder caches, but the drive processor can.

Actually, HDDs are still on a steep downward price curve. The amount of
HDD space you get for USD 100 keeps going up, up, up. Look at portable
backup drives.
