I have an old 700 MB WD IDE drive that still works fine and has about 6 
years 24/7 survived. And I also had a 2000$ 73G SCSI IBM drive that lasted 
for about 5 monthas and was that damadged that Convar sent it back without 
one byte recovered! And I don't want to remember the 80GB WD drive that 
lasted for 2 months......
Please, don't discuss about SCSI/ATA reliability, there are bad 
designed/produced drives and there are good ones. You can't tell before, 
only experience counts.
I can say only good things about Seagates Barracuda 7200.8 drives for 
example. Some dozends are running for two years without _any_ single drive 
failed. Also the Samsung (p)ATA drives are still running without any 
single failure. And WDs once were perfect drices, but they also produced 
crap. So you can't even be sure by vendor!


P.S.: I'm planning to bring up a FreeBSD site which reflects hardware 
compatibility experiences as well as long term experiences. I'll be back 
if I have more...
