YMMV, obviously. I've used WD for years, with minimal problems. Of
course not *zero* problems, because drives die.

I've had Seagate drives go bad at about the same rate as WD. Seagate
used to have a basically unusable RMA system (this was many years ago),
which is why I leaned toward WD. Now that Seagate has fixed their RMA
system they're more or less equal when I'm ordering drives.

The main problems I have seen are the ones customers purchase
from Best Buy: low bid, cheapie.

Keith,

You missed part of what I said. I too will not sell
the regular Seagate drives. They are not much better
than the WD ones. I sell the "Enterprise" level drives.
They are specifically designed to run 24/7 in data centers.
In other words, I recommend the drives build for servers
not workstations.

Here is a link to them:
http://www.seagate.com/www/en-us/products/servers/barracuda_es/
I have them spread over two counties: zero defects

And in prior years, I would not sell Seagates at all. They
use to be such trash. And, WD use to be so good too, but
they pissed that away. The main problem I see is the
cheapie (low bid) drives purchased at Best Buy.

Hope I cleared that up.
-T

p.s. WD now sells an "enterprise" drive too. I do
believe it is called the "Raptor", but I am not sure.
I am still too chicken to use WD with all the troubles
I see coming in from customers. (They are cheap
for a reason!)

Okay, but WD sells ''enterprise'' drives too. I've been using this
model with few problems:

http://www.wdc.com/en/products/products.asp?driveid=610

They make SAS enterprise drives as well. But I've also used their
''desktop'' drives, also without major problems. But then again, I've
always used these drives in a redundant RAID, so if a drive happens to
fail I don't lose data. But it would still be a PITA to RMA drives
regularly, and I would not use drives that I had bad experience with.

I have some of these as well, but not with zero defects. Zero
defects is an unreasonable expectation, especially if you have a large
data center (I do not, but I do have a fair number of drives).

How often does that happen?

A few years ago, I got one of those every month or three. IIRC,
after a later distro release, they quit happening with _NO_
change in disks or disk-related hardware. Actually, there might
have been a power supply replacement in there, too. If they're
more than a week apart, my bet would be on a kernel bug. If
they're more often than every day, my bet would be on hardware.
