Another weekend, another set of ZFS scrubs of work's multiple terabytes of data sitting on a collection of consumer 4 TB SSDs (mirrored, we aren't crazy, and also we have backups). As usual there is not a checksum error to be seen. I think it's been years since any came up.

I accept that SSDs decay (we've had some die, of course) and random read errors happen, but our ZFS-based experience across both HDDs and SSDs has been that the rate is really low for us. Probably we're not big enough.
