After reading http://www.postgresql.org/docs/current/static/wal-reliability.html, I tried the recommended diskchecker.pl <http://brad.livejournal.com/2116715.html> but I am not satisfied: I always get: Total errors: 0 even if I tested with with a HGST HTS721010A9E630 that the vendor's datasheet (http://www.hgst.com/sites/default/files/resources/TS7K1000_ds.pdf) advertise as " Designed for low duty cycle, non mission-critical applications in PC,nearline and consumer electronics environments, which vary application to application " Since it is not, a high end disk, I expect some errors.
Why? Just because a disk isn't enterprise-grade doesn't mean it has to lie about fsync, which is the only thing diskchecker.pl tests for.
