[j-nsp] High failure rates for M7i/M10i hard disks?

[Scott Morris]

I dunno, I have laptops that have been on 24x7 for well over a year now, and
they haven't crashed.  *shrug*

I'm not going to defend Juniper here - I think we have suffered quite enough
of these disk problems (got woken by a phone call from our NOC this morning
- *another* M7i had stopped working during the night, from the same
problem).

However, I *think* what they're saying is that writes every 10 seconds for a
while is not a problem, but writes every 10 seconds 24x7 may be a problem.
Remember what the disk manufacturers have been trying to tell us - there are
differences between disks made for heavy-duty server use (typically SCSI)
and disks made for PC/home use (typically ATA). The M7i/M10i disks are 2.5"
ATA disks (laptop type disks) and are probably not made for continuous use.
