I was using bcache at one point at World Gaming, with a borrowed flash card, 
but luckily stopped doing so just before a (possibly different) corruption 
problem.

I just saw a report of corruption problems with bcache in conjunction with GCC

https://en.wikipedia.org/wiki/Bcache
- a layer in the kernel for using fast storage (e.g. - NAND, SSD) as a cache 
for spinning rust

That's pretty cool; I don't have enough lurking SSD/NAND to have that be of 
*too* much interest.  But wait, they kept working on it, so there's a 
filesystem...

https://en.wikipedia.org/wiki/Bcachefs
- a COW (Copy On Write) filesystem running atop BCache that has the modern 
stuff people seem to like such as snapshotting, encryption, checksums, 
compression (ala ZFS, Btrfs)

Here's the corruption reference: 
https://bugzilla.kernel.org/show_bug.cgi?id=203573
And some more diagnosis here: 
https://bugzilla.redhat.com/show_bug.cgi?id=1708315

Sounds like it may be the wrong moment in time to be adopting BCache-related 
stuff ;-)

Has anyone been poking at this sort of stuff?  A *loooong* time ago, I used to 
follow ReiserFS pretty closely, back when that project was a technical matter, 
as opposed to being (rather properly!) overshadowed by a murder investigation 
:-(

When confronted by a difficult problem, solve it by reducing it to the
question, "How would the Lone Ranger handle this?"
