Well, I got a replacement drive today, so if this one fails, I have
another one standing by.  I'll need to see more clear indications that
the drive is actually in trouble before swapping them, however (I have
backups and only /var and /tmp are on the drive, so I can afford to wait
and see).

The self-tests I run with smartctl show no errors, but the UDMA CRC
error count for /dev/ad10 is non-zero, as is the soft error count.  I
don't know how much I can trust these numbers.

I could buy a dozen of these drives for the cost of one equivalent SCSI
drive.  SCSI is nice, but it's awfully pricey, for no good reason that I
can see, and unless one is running a very heavily loaded server, I'm not
sure that I see the advantage to it.

I was thinking a few days ago that extremely fast static RAM might be
the single best way to boost system performance, but that was just
daydreaming.  (From what I understand, most modern processors spend most
of their time in wait states waiting for memory to reply.)
