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. > Modern drives with the exception of high end SCSI ones, are as a > friend of mine put it once: "slapped together a million miles a second > on the assembly line" 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.) -- Anthony
