What about something like this CF card with a microSD slot?

You can use whatever CF>IDE adapter is convenient for you, with the flexibility of using microSD cards. They are also on Amazon of course, but they're twice as expensive for exactly the same thing.

There is this thing:
https://bignoiseradio.com/product/akai-mpc-20 … ard-reader-kit/

Pricey and limited to 1gb, but it does “hot swap” and comes with a metal face place and mount. I have never used one. Looks like it is intended for a synth, but says “ide atapi”

That's really hard to bite on when these are even cheaper directly from China: https://www.amazon.com/SDHC-40Pin-Adapter-Mem … e/dp/B08SK28S2Y

They are just missing a bracket with a small notch for the card, and two screw mounts. But I've only ever seen CF adapters with them. It makes no sense the SD ones never have them. https://www.amazon.com/Syba-Connects-3-5-Inch … R/dp/B001JTO782

It's just another sintechi SD-IDE bridge, but with a 50pin instead of 40 pin IDE port.

They can be tricky because many require 3.3v, and not many CF adapters provide clean 3.3v.

The poster wanted something with a metal mounting bracket.

I stumbled across this thing, but it's PCIE, not mSata : http://ableconn.com/products_2.php?gid=125

Sort of like this but in a different shape:

Interesting. So one of those would probably work in a camera or something that can properly supply 3.3v or 5v, but not in basic IDE CF adapters that lack a suitable 3.3v supply.

I have a bunch of these:
https://www.aliexpress.us/item/3256801622107339.html

And you're right, there isn't any kind of 3.3v supply on this thing.

By chance have you tried combining the SD>CF adapters with a basic IDE>CF adapter like the one above? That's a real shame if the SD>IDE bridge would cause the device to not be compatible with 5v supplies at all... but I see that the specs do say that it is 3.3v. Still, if there are any additional components inside that allow 5v operation this wouldn't be the first time that an aliexpress listing left out such a detail. Though, for as cheap as it is, you're likely correct and it will only operate at 3.3v.

EDIT: Ah, I see this has all been covered hear several years ago!
SD->CF (Secure Digital to Compact Flash) Adapter for use with CF->IDE adapter.

Hard to believe that THESE adapters and THESE 3D printable brackets have been available for 5+ years, and yet no one is selling one of those adapters with a metal bracket attached already.

Yes, pretty much that bracket, but full size rather than low profile, with the slot and mounts in the right position.

There are several variations that are 3D printable. But as I said they flex which a metal one wouldn't. https://www.printables.com/model/793159-micro … de-slot-bracket

Take everything with a grain of salt because a different driver or different controller might produce very different results if it negotiates a different ATA protocol.

Here are the devices:

The Transcend CF220i puts up some impressive numbers that rival Bridged Sata SSD's.
The Western Digital SiliconDrive looks like it is stuck in PIO. PIO be why it has the lower latency

I got ahold of a 1GB Transcend 220i CF. Same solid response time as the 4GB, but 2/3's the buffered read, 1/2 the linear read, and 1/3 the write speed.
