If this drive doesn't support tagged-queueing, is the write cache disabled? I get that sort of performance from a (PATA) disk with the cache disabled (hw.ata.wc="0" in loader.conf) >According to smartctl, the drive runs at 56C during the copying.

If the drive really is running at 56°C, it won't last very long. -- Peter Jeremy _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
