"EAMR offers similar density gains to HAMR and MAMR, with less exotic tech."
Wow, that reminds of the good old Prime mini days with the $250,000
twelve platter twelve inch hard drives.
SSD is definitely coming on strong. I keep on wondering if the
holographic media is ever going to be useful.

I can't tell if you're serious. I mean, obviously not, but no smiley anywhere, so I'm not sure.
Tape has never been a viable random access medium and never will be.
If you're a glutton for punishment, I suppose you could use it for archival purposes, but even that's a stretch these days. Check with your local
museum to see if they have a tape system they're willing to part with. There's a reason why all of the big data storage organizations use hard drives exclusively.

I've had a very similar experience, on more than one occasion. The tape recorder looks like it's doing its thing and the folks say they're doing
what they're supposed to do, like putting on a fresh tape each night at midnight and doing the periodic routine maintenance, but when you get a
call asking you to load yesterday's tape and it's empty, your heart sinks.

That's exactly the point! Modern HDD designs are taking away their
random access features and replacing them with serial-access features.
If you're going to be using serial-access devices, then it might as well
be tapes. All of the random access is beginning to be done (and done
better) through SSD's, so with tape capacity being higher than HDD's,
and random-access features being better on SSD's, HDD's are going to be >squeezed out.

arrays?
No, and I'm not likely to at this point. Those systems were obsolete at
least 20 years ago, although I'm sure there are a few holdouts here and there. The few that might still be in operation are just waiting to be replaced with modern technology.

Since when? I don't think you know how important these are to enterprise >backup solutions.
Millions of dollars are spent every year on installing
new arrays, and hundreds of thousands are spent on tape media. They're

This is not something that is legacy, and going down, the
expenditures are going up, because it's the best way to backup data.

What do you think SMR is? SMR requires a serial write pattern to
optimize its writing performance. If you try to write to an SMR drive in
a completely random way then performance drops 10x. HDD's are thus
becoming more serialized devices.
