Thats funny. The first thing that popped into my mind is something a former coworker used to say, "the beatings will continue until morale improves."
Seriously, though, and without turning this into a hard drive flame war, because I know we all have our war stories, but is there a particular brand that seems to fare worse than the others?
I know that for me, in the far distant past, I managed a couple of dozen Sun servers. Even though Sun supposedly "only got the top 10% of all Segate drives produced," I had 6 Seagate SCSI drives fail in less than 6 months. It got to thte point where my reseller knew that if I called, to order up a replacement Western Digital.
I'm just curious if others have seen similar (albeit more recent) experiences like this.
Sorry if this is pushing the limits of off topic.

Interesting....what tests in bonnie++ did you run?
DB access to a single file?
Create/write/delete small files?
Others?
Just curious, so you beat the disk senseless with bonnie++ for a day, and if the drive does not fail, when put into service, how long does it last (based on your experience)?
How was this one day duration arrived?
(The implication is that if the drive survived the test for one day, you can rule out infant mortality, and expect the disk to last to meet the mfg MTTF?)
I have read several anecdotal articles that concluded USB and FW disks in their own enclosure have a higher probability of infant mortality....unfortunately they weren't tested in a scientific manner....
thanks

I had a period of time where I bought a bunch of external USB/Firewire
drives, of all different brands; and I found that fully half of them would
die after having bonnie++ run on them for a day or less. this included a
really expensive shock-mounted ultra-high-speed drive.
