Any benefit to changing sector size on Intel DC S3710 SLOG?

[xyzzy]

I just learned that the Intel DC S3710 firmware can be set to use 512e sector size (the default) or 4K.

Intel calls the setting the "physical sector size" but it seems to me that you're really changing the logical sector size.

Terminology aside, is there any benefit to doing this on a SLOG device?

512e, perhaps if your pool has ashift 9. Otherwise, it seems like it could be a better idea to go 4K, as that might stress the SSD's page allocation a little less, but best guess is that there's been some substantial work put into optimizing for this kind of use. You'd probably have to try it both ways to see.
