The drives I'm using are 7 x WDC WD20EARS-00M (3 are AB50, 4 are AB51) and 1 x WD20EARX-00P AB51. The WD20EARX-00P AB51 is a SATA 3 (6 Gbps) drive but the others are all SATA 2 (3 Gbps). I know the driver doesn't like mixed speeds in IR mode but I'm flashed with IT firmware as ZFS is doing my RAID (raidz2). I was having problems with the WD20EARX-00P AB51 drive being faulted by ZFS until I updated the firmware to 11 and now ZFS is happy (I've also done a full extended drive SMART test and the drive is fine). So what do people suggest (before reversion to r230921) ?
