> have killed off high-RPM hard drives
Depends, 15k RPM are indeed gone. 10k RPM drives are sold and used.

As far as I can tell, WD's 10k RPM drives are discontinued and no longer listed on their site. Seagate lists 10k RPM drives up to 2.4TB and 266MB/s, with a 16GB flash cache. Looking on CDW, it's more expensive than a 3.84TB QLC drive. It uses more power at idle than a QLC SATA SSD under load. I can only imagine a few workloads where the 10k RPM drive would be preferable to the QLC SSD, and I'm not sure the 10k RPM drive would have better TCO than 7200 RPM drives for such uses.
Are there any situations that you think still call for 10k RPM drives to be selected, rather than merely kept around due to inertia?
1) A high-throughput MX/message broker server that is set up and works next 10 years without a need of drive replacement.
2) ZFS SLOG (or any similar scratchpas/transaction log) for 24/7 intensive writes.
In both cases similarly reliable SSD (enterprise ssds) would cost more and require more frequent replacements.
