Hmmm, I must not have tested both disks at once before on the 3132: One at a time: dd if=/dev/ad18 bs=1m count=1000 of=/dev/null 1048576000 bytes transferred in 8.807009 secs (119061534 bytes/sec) dd if=/dev/ad20 bs=1m count=1000 of=/dev/null 1048576000 bytes transferred in 8.800526 secs (119149243 bytes/sec) Two at once: dd if=/dev/ad18 bs=1m count=1000 of=/dev/null & dd if=/dev/ad20 bs=1m count=1000 of=/dev/null 1048576000 bytes transferred in 13.766050 secs (76171160 bytes/sec) 1048576000 bytes transferred in 13.799268 secs (75987799 bytes/sec) so 152 MB/s total rather than the expected ~238. PCIe x1 slot is supposed to be good for 250 MB/s, so it ought to be able to max out both disks at once, or at least get close. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "[email protected]"
