SATA? Make/model? HBA? SATA. Currently Intel SSDSC2BB24 but like I said, we've tried several. HBA is a Supermicro AOC-S3008L-L8I (reports itself as a LSI3008-IT). Firmware has been updated to latest on all controllers. We've purchased an LSI 9300-8i and scheduled downtime to install it, to see if we can rule out a bad controller. > Are you mixing SAS and SATA on the same bus? No, the pool is on separate HBAs.

We've tried various numbers and configurations of log devices, anywhere from 4 to 8 devices, both mirrored and unmirrored. -- M.
